PREFACE of‘‘AMS SPECIAL-ISSUE‘‘ 

DEAR READERS, 

This issue, which is dedicated to the upcoming BAUMA 2010 

that will be held in April in Munich, will consist of a one-time 

special edition of our scientific journal „ADVANCED MINING 

SOLUTIONS“. 

The BAUMA 2010 Trade Fair in Munich 

Presents Itself in a Sensational 

Dimension! 

Once again this time in April in Munich, the international 

trade fair for Construction Machinery, Building Material 

Machines, Construction Vehicles and Equipment presents 

itself as the world’s largest fair in terms of area. The 

record area of 555,000 square meters already reveals the 

dimensions of this fully booked event. In order to meet the 

booking demand, new temporary halls have been set up 

prior to BAUMA. Thus, the BAUMA of this year achieves 

dimensions, which have not been achieved before. 

Based on the current state of knowledge, over 30,000 

exhibitors are expected to attend BAUMA 2010, with a 

record share of 50% international exhibitors. Compared to 

2007, this constitutes a further enhancement of BAUMA’s 

international character. 

The scope of this huge event, as well as the support of 

the numerous exhibitors in times of the general economic 

crisis reveal that in most of the industrial and threshold 

countries, the construction sector has grown more that 

the entire economic activity, thanks to public economic 

stimulus packages. The great interest in this exhibition 

evokes hope that in most countries, rising growth rates 

for the construction sector can be expected for the year 

2010, and even more for the year 2011. The BAUMA 2010 

sets the stage for the time after the crisis. The long-term 

outlook for the building industry, for the construction 

materials industry, for mining and for engineering can be 

positively assessed globally, due to the rapidly growing 

markets of Asia and other regions, like for example Brazil. 

Although the high growth rates of the years 2003 to 2008 

are a thing of the past, for the year 2011 onwards, growing 

markets in the construction industry are predicted for 

India and China in particular, and in a smaller scope for 

the US, Russia and Europe. 

Issue 01 | 2010 www.advanced-mining.com 

6

Since the year 1954, in which BAUMA was held for 

the first time, the exhibition has undergone a constant 

development and has evolved into a globally leading 

exhibition for the entire construction machine industry. 

Thanks to its ever new record numbers it has grown into 

the biggest trade fair of the world. The internationally 

announced BAUMA innovation award, which is being 

awarded at the beginning of the exhibition, shows that 

BAUMA has also developed into a market place of 

innovative technologies and innovations in this sector. 

The subject of environment 

and sustainability is also part of 

the comprehensive spectrum 

of this year’s BAUMA 2010. One 

main focus of the near future 

is for example the reduction of 

emissions, due to the fact that new exhaust guidelines 

are coming into effect. Since the Guideline 97/68/EG and 

the US-exhaust law „Tier 4 interim“ have been tightened, 

new threshold values for emission of non-road vehicles 

like dredgers, road rollers and milling machines will 

come into effect soon. The regulation of lower exhaust 

values challenges the construction machine sector into 

developing new, alternative technology solutions. As 

an example it is required to reduce threshold values for 

particles by 94 percent, compared to the current stage 

III A. Previous engine modifications like mechanical and 

electronic control, common-rail systems, charging and 


exhaust gas recirculation alone will not be sufficient 

any more. In order to meet the regulated reduction of 

emissions with new technological lines of sight it will be 

necessary to rethink and further develop in the area of 

exhaust after-treatment. It will be interesting to discover 

the answers that manufacturers have found. 

It is for the above-mentioned reasons that, prior to 

BAUMA, we have decided to use the new dimensions 

of BAUMA as an occasion to issue a special edition in 

which we are aiming to inform on selected innovations, 

new technologies and product novelties, which can be 

discovered and experienced on the exhibition from the 

19th to the 25th April 2010. In this issue we will slightly 

deviate from the usual form of our magazine, in order to 

adjust ourselves to the innovative character of BAUMA. 

Instead of the section on “Further Training”, which is 

being continued in the next issue of AMS, we will report 

on the BAUMA innovation award. The nominations 

of this award are differentiated and assessed in the 

five categories of machinery, machinery component, 

construction process / construction work, research and 

design. 


7

In judging the nominated innovations, the jury of experts 

has paid particular attention to the following criteria: 

• Forward-looking development 

• Practical use 

• Contribution to environment and humanization of 

work 

• Improvement of efficiency and productivity while 

reducing energy and costs at the same time 

• Image value for the construction equipment, building 

material machinery industry or the construction and 

building material sector 

There are three nominations in each category, and the 

award is being given to one of each at the onset of the 

exhibition. Within the framework of this special edition 

we will introduce to you a selection of the innovations 

that we believe are the most spectacular ones. 


This is followed by our “Transfer of Technology” 

section, in which we present some new technological 

developments, as well as first experiences in the 

application of new technologies. Subsequently, in our 

“News and Reports” section you will find a selection 

of current product novelties, which on the occasion 

of BAUMA are being presented to the expert public by 

manufactures for the first time. 

We thank you for your trust and hope that we manage 

to please you with this extraordinary special edition.

New product! New vertical 

drilling machine TERRA-DRILL 

for geothermal power 


With 35 years of experience in horizontal trenchless pipe and cable laying the Swiss manufacturer TERRA AG has 

joined the vertical drilling market with the development of its TERRA-DRILL. The design of this new vertical drill for 

geothermal power has taken 2 years. The aim of this intensive devolvement was to develop a compact geothermal drill 

that would be as powerful as conventional large drilling machines, but small enough to be employed in residential 

gardens for the heating of existing old buildings. 

New Design 

Most often, large vertical drilling rigs cannot be used in 

gardens, as their massive weight and steel crawler tracks 

ruin the existing garden. If they are to be used, 

they are often lifted into the garden, which is 

difficult and expensive. This is why the TERRA- 

DRILL has a modular design. Drill rig and power 

pack are separated. In the transportation mode 

the TERRA-DRILL is only 0.95 m (37.4”) wide. It 

can drive through 1.00 m (3.3 ft) wide entrance 

doors. Its low weight of 2.1 tons (4’620 lbs) and 

it is rubber crawlers prevent damage to the 

garden and pathways. 

Machine technology 

The TERRA-DRILL 4407 V can drill vertical 

bores up to a depth of 120 m (400 ft) in most 

ground conditions. It has a torque of 4’400 Nm 

(3’300 ft.lbs) and a pull back force of 70 KN 

(7 tons). Casing pipes up to 178 mm (7”) OD 

can be drilled down to the upper rock edge. 

These casings protect the bore channel from 

collapsing. Smaller casing pipes with 133 mm 

(5.2”) OD and 152 mm (6”) OD can also be used. 

The 5“down-the-hole hammer is equipped 

with a drill bit of 150 mm (6”). It drills through 

most rock and mixed ground. This large 5 inch 

bore channel allows the geothermal sonde to 

be lowered the final drilling depths. 

The 5“ down-the-hole hammer is powered 

by an air compressor supplying 19 m3 /min @ 

21 bar (630 cfm @ 3’000 psi) to reach optimum 

productivity. If smaller compressors are to be 

used, a 4” down-the-hole hammer is offered. 

The drill rods are 1.5 m (5 ft) long and have a 

diameter of 89 mm (3.5”). 

Pic. 1:

V for geothermal bores. 


10

The TERRA-DRILL is equipped with a small power 

pack allowing it to be self propelled. The separate main 

hydraulic power pack is driven by a 24 kW (33 HP) Diesel 

engine, which is “clean” and fulfils the world wide 

environmental emission requirements for the foreseeable 

future. 

The duplex piston pump in the power pack hydrates 

the compressed air to ensure a continuous discharge of 

the drilling mud. 

The new patented duplex connector 

(mud spill preventer) 

The TERRA-DRILL operates with only one driving 

head. Thus TERRA has designed a new patented 

duplex connector (mud spill preventer) which allows 

simultaneous insertion of the casing pipe, the down-thehole 

hammer and the drill rods. The duplex connector 

conducts the drill mud cleanly into the mud containers 

ensuring that the job site is always clean. As soon as the 

casings have reached the upper rock edge, the bayonet 

connection of the duplex connector is released. From 

that moment on only the drill rods with the down-the-hole 

hammer proceeds to drill further down. 


Triplex clamping and break-apart 

system 

The TERRA-DRILL is equipped with a triplex clamping 

and break-apart system. The assembly and disassembly of 

the casings and the drill rod is undertaken hydraulically. 

Cable winch with handling device 

The electric cable winch and the specially developed 

rod handling device enables the lifting and loading of a 

single casing and a single drill rod simultaneously into the 

drill rig whereby they are assembled hydraulically. The 

handling device is also used for the disassembly of the 

heavy casing pipes. 

Air drilling and fluid drilling 

In rocky ground it is recommended to use the air drill 

method with the down-the-hole hammer as it is faster. If 

the geology consists of loose ground, even at great depths, 

the TERRA-DRILL can be equipped with an optional drilling 

fluid pump to allow drilling using the “fluid method”. Here 

up to 600 ltr/min (160 gpm) of bentonite drilling fluid is 

pumped into the bore channel with a pressure of 4-6 bar 

Pic. 2: 

The TERRA-DRILL can be manoeuvred through 1.00 

m (3.3 ft) wide entrance doors to drill in confined 

gardens. 


11

(60-90 psi). This drilling fluid is pumped through the drill 

rods and tricone chisel at the drill face and forces the 

bentonite back to the top of the bore to stabilise the bore 

channel and remove the spoil. At the top the Bentonite is 

conducted via the duplex connector (mud spill preventer) 

into both mud containers. 

Supported by the BFE 

Pic. 3: 

The newly designed and patented duplex connector 

(preventer) allows a simultaneous drilling of casings 

and drill rods. It conducts the drill mud cleanly into 

the mud containers without spillage.. 

The Swiss association “Gütesiegel Erdwärme“ 

(Association for Geothermal Drilling Companies) has 

published, that 1.400.000 meters (4.600.000 ft) of geothermal 

earth drilling had been completed in Switzerland in 

the year 2007 using large drilling rigs. At present there 

are approximately 300 large drilling rigs operating in 

Switzerland. The Swiss Federal Office for Energy (BFE) 

supports the design of the completely new geothermal 

drill rig TERRA-DRILL with the aim of utilizing geothermal 

power even in small residential properties.

Innovative drilling 

procedure for below-surface geothermal energy 

With the use of the electro-impulse procedure (EIV) decisive savings in drilling costs 

can be reached for below-surface geothermal energy. In the earth‘s crust (lithosphere) 

there are nearly inexhaustible reserves of thermal energy stored. In order to produce 

electricity from this, the hot dry rock technology is used. For this, at least two drillings 

are sunk into the hard bedrock. Hereby. one drilling serves as injection drilling, the 

other is an extraction drilling for the heat transfer medium. The rock functions as heat 

exchange. 

Pic. 1: 

Destruction of rocks by electro-impulse procedure in different kinds of rock 

(Granite, Basalt, Limestone, Sandstone). 

Above ground, the extracted heat is conducted to 

a steam cycle by which a turbine can be moved. This 

technology offers the opportunity of building a base load 

power plant independent of the wind and the sun. The 

required temperature level in the rock for an economical 

power plant stands at 130°C and is reached only at depths 

of 3000 m. Conventional drilling equipment is suitable 

for the sediment rock of oil - and gas deposits. In rock 

such as granite it drills only very slowly (1 – 2 m/h) and 

wears out quickly (a lifespan of 50 – 60 h). Changing the 

equipment due to the wearing out, so-called roundtrips, 

is very time-consuming as the entire drill string has to be 

dismantled and then reinstalled. At a drilling plant‘s daily 

cost of € 18,000, these standstill times run up enormous 

costs. Depending on the case, the total costs come to € 

8 – 13 Mi for 5,000 m of drilling. The economic success of 

a below-surface geothermal energy project is connected 

to the availability of an economical drilling technology. 

EIV offers a technical alternative to the conventional 

drilling procedure. It uses the destructive effect of the 

high energy electrical charges which are produced 

inside the to be loosened material. The loosening process 

is, then, fundamentally changed. Instead of the ultimate 

compressive strength of the rock, its tensile adhesive 

strength must now be overcome. This means a reduction 

of the loosening resistance of 90% in the mean. 

The electrical voltage used consists of 300,000 V and 

discharges itself within 1/10,000,000 s. The pressure 

and the temperature in the resulting breakdown canal 

increases abruptly, which causes the rock structure to 

fail. Hereby,the electrodes between which the breakdown 

is produced are lying on the rock only loosely. 

In the framework of a project supported by the Federal 

Ministry of Environment, Nature Conservation and Nuclear 


13

Safety, a machine concept was developed by which this 

innovative loosening procedure can be integrated into 

the drilling technology. Thereby, a down-hole-tool was 

created that can be integrated into the drilling process 

like a conventional drilling tool. Changes to the drilling 

plant or additional equipment is not needed. 

Supplying the energy takes place via a flush-driven 

drilling engine which runs an electric generator. Its voltage 

at the start is reshaped over a rectifier and conducted to 

the surge voltage source (Marx principle) which generates 

the surge voltage for the output process. The output 

electrodes are arranged in such a way that the drilling 

hole floor level is reduced full-surface without the EIV 

drilling system having to rotate in the hole. The discharge 

of the drilling cuttings takes place in the conventional 

mode via flush – drilling. A flushing-medium that satisfies 

electric drilling and electrical requirements has already 


been tested successfully. The technical challenge for 

the practical implementation of the EIV drilling system 

consists foremost of the adaptation of the electrical and 

electronical components to the high temperatures of up 

to 200°C in the drilling hole. Additionally, there are the high 

pressures of 100 bar and the small drilling hole diameter 

of 12 1/4“ (311 mm). Concepts on the basis of already 

existing technical solutions show that the realization of a 

prototype is possible despite these high requirements. 

The main advantage of the EIV drilling system is 

that wearing out does not occur due to the absence of 

mechanical forces to the mining equipment. A burn-off of 

the electrodes due to the charges is not to be expected. 

The lifespan is presently estimated at 500 h. The number 

of equipment changes due to wearing out is minimized. 

The aim is to completely avoid them. In addition, there is 

the to be expected drilling speed in the granite of 4m/h.

Picture of the innovation 


14

The savings potential in respect to 

the drilling costs is calculated at 30% on 

the basis of the average return method 

with drilling data from practice. The 

result of this development shows that 

the utilization of the EIV technology 

makes it possible to lower the drilling 

costs and, hence, the energy accrual 

costs for below-surface geothermal 

energy to that of the water-and wind 

power level.

Die BAUER Maschinen GmbH - 

nominated for the BAUMA Innovation Award 2010 

A new development of Bauer Maschinen GmbH was nominated for the BAUMA Innovation Award 2010 in the category 

„Machinery Component“. What is simply called „Down-The-Hole flushing head for dry drilling rods“ represents a 

breakthrough: This Bauer innovation enables to significantly increase the performance of Kelly drilling rigs for drilling 

in rocks. Additionally, this innovation results in an ecological benefit: The „Down-The-Hole flushing head“ supersedes 

the cost-intensive set-up of a slurry drilling system with slurry tank and slurry treatment plant. This new method has 

been successfully used several times: In May 2009 in Finland, since then also in Russia – in Vladivostok, and for the 

building projects of the Olympic arena in Sotchi–, in Singapore and in Australia. 

The Bauer Down-The-Hole flushing 

head 

The Kelly drilling system is the most efficient method 

for the production of bored piles as the intermittent soil 

extraction from the borehole is not energy efficient and 

the drilling tool can be selected for each soil layer without 

any loss of time. Furthermore, the required space for the 

equipment and the boreholes are reduced to a minimum. 

Upon drilling in very strong rock – as often 

required - passive drilling tools, also with the 

use of roller bits, can only achieve a very slow 

drilling progress as the loosened rock chippings 

are not instantly removed and therefore strongly 

interfere the further loosening process of the 

rock by the roller bit. Due to the telescoping of 

the Kelly bar and the permanent rotation of the 

drilling tool, the supply of flushing energy to the 

drilling tool was not possible until now. Longtime 

efforts to seal the Kelly bar and to turn it into 

a „flushing Kelly“ or to direct a simultaneously 

rotating hose downwards were never successful 

or suitable for jobsites. 

Previously, an improvement was only achieved 

by an extensive refurbishment of the drilling rig 

towards a flush drilling system with multiple drill 

pipe sections and the respective method for the 

slurry circulation (flushing head, slurry tank, etc.); 

there was a high demand of energy for the fluidic 

extraction of the rock chippings throughout the 

complete length of the borehole. 

Pic. 1: 

Practical use of 

Down-the-hole-flushing head 

Upon reaching the rock layer, the newly developed 

Down-The-Hole flushing head can be used together with 

the subjacent roller bit full section drilling head or a roller 

bit core barrel – as any other Kelly drilling tool – coupled 

to the Kelly bar. An air supply hose which is coiled outside 

the borehole is connected to the Down-The-Hole flushing 

head. 


16

If the drilling tool touches the drilling horizon and is 

pushed downwards by the feeding system of the drilling 

rig, the stator of the Down-The-Hole flushing head is seized 

with the lever system at the borehole wall. This avoids the 

connector of the air supply hose to simultaneously rotate 

with the rotor, which transfers the rotation of the Kelly bar 

to the drilling tool. 

The air flushing is conducted to the rotor via the 

pneumatic multiport swivel and drives the flushing by 

risers in the drilling tool using the air-lift method. The rock 

chippings are permanently transported to a tank in the 

upper part of the drilling tool. The transport of the loosened 

material to the surface is intermittently carried out in the 

same way as upon Kelly drilling by retracting the Kelly bar 

and emptying the tank outside the borehole. 

Pic. 2: 

Schematic illustration of 

Down-the-hole flushing 

head 


With the same method, besides air also water, hydraulic 

oil or electric current can be lead downwards, which for 

example also enables the driving of a Down-The-Hole 

hammer.

Norton-Clipper 

- Foam Drilling System 

The patent-pending Foam Drilling System from Norton-Clipper 

is an innovative solution for diamond drilling in reinforced 

concrete. It replaces water as a coolant with foam. 

The Foam Drilling System 

Using foam as a coolant allows a much easier 

collection of the coolant and slurries which means ability 

to work on job-site that need to remain very clean and 

exempt of water contamination; this can be for instance 

drilling holes for pipes in a inhabited house, where it is 

very difficult to perfectly protect the surrounding; this can 

also be very regarding job sites like nuclear plants where 

water contamination is forbidden. An obvious benefit is 

time saving : instead of spending hours to protect the 

surroundings against water spraying, or to clean the job 

site after drilling, the contractor can install his equipment 

very quickly and leave the job-site without spending time 

to clean it. This brings great benefits for instance on small 

renovation job sites. Another benefit is saving of water : 

to generate the foam, water is mixed with a environment 

friendly foaming agent, however while drilling, the 

consumption of water is reduced by 2/3 thanks to the 

effect of the foam! 

This system can be used jointly with all standard wet 

drilling rigs and motors existing on the market, so the 

contractor does not have to invest in additional equipments. 

However it cannot be used with standard diamond 

corebits : it requires special type of corebits, adapted to 

foam drilling, and developed by Norton-Clipper. 

The Foam Drilling system is made of a compact and 

easy to move foam-drilling-unit (including a compressor 

and a tank, which is transforming water into a foam having 

the right consistency), a transformer tank and a vacuum. 

Foam drilling will soon become the preferred solution for 

professional drilling contractors.

Glass beads instead of gravel or sand 

as a supporting material in bore wells 

AN INNOVATION FROM OCHS THAT GUARANTEES THAT WATER CATCHMENT 

WELLS HAVE A LONGER, BETTER AND MORE ECONOMIC SERVICE LIFE. 

Glass beads as a supporting material in 

bore wells 

Pure and clean water is the most important raw 

material for human life. Bore wells are required to extract 

ground water. These wells consist of three essential 

components. 

• The bore hole, the depth and diameter of which are 

determined by the position and thickness of the waterbearing 

soil layers to be opened up. 

• The well filter pipe to be fitted inside the bore hole, through 

whose slots water can flow from the well pipe. 

• The supporting material in the annular space between the 

fixed bore hole wall and the well filter pipe. 

The selection of this material is of 

crucial importance when constructing 

wells. Its purpose is to support the 

layers of soil particles at the wall of the 

bore hole in such a way that clear and 

sand-free water is able to pass through 

the free pore spaces to the well filter 

pipe with as little resistance as possible. 

Selecting the right particle size and 

material is of crucial importance for the 

strength and problem-free operation of 

the well over many years. If the material 

is too fine, an unwanted filter effect will 

be created and block the pore spaces 

with the consequence that the well 

will run dry. If the supporting material 

selected is too coarse, the well will 

permanently transport sand particles 

and cloudy material with the water from 

the bedrock. 


Gravel or sand has been used as supporting material 

until now. In Germany, these are recorded in DIN 4924 for 

well construction that describes the minimum required 

material properties. Naturally occurring gravels and sands 

impose limits on the requirements in terms of roundness, 

dimensional accuracy, surface quality and, in particular, 

the strength of the individual particles needed by modern 

well construction. 

The innovations from OCHS GmbH consist in using glass 

beads as a supporting material between the bore hole 

wall and the well filter pipe. This pipe has the following 

decisive benefits for well construction: 

Pic. 1: 

Comparison of conventional gravel and glass beads 


20

• Between four and ten times greater strength than 

comparable sand and gravel material 

• Optimal roundness for virtually the same particle size. This 

results in a greatest possible free pore space, regardless of 

the size, through which water can flow unimpeded. 

• A surface that is virtually perfectly smooth 

• Optimal size adjustment to the water-bearing soil layers 

is possible, as the glass beads can be produced between 

0.4 mm and 16 mm diameter at 0.1 mm intervals. 

• Hygienically safe material combined with high chemical 

resistance, e.g. to disinfectants 

The smooth surface, in particular, with the virtually 

perfect roundness of the glass beads guarantees that 

the water catchment wells can be operated more 

economically. Water can flow through the glass beads 

unimpeded with as little resistance as possible. This can 

result in high potential savings in the electrical energy 

required to transport water from a great depth, as the 

overall fall in the water table in operating the well is 

reduced. 

As glass beads can be supplied without undersized and 

undersized particles, these can be optimally adjusted and 

fitted to the native soil. The slot width of the filter pipes 

can, in turn, be adjusted to the size of glass bead selected 

and therefore enables water to flow as far as possible 

unimpeded from the soil layers to the pump. 

A great deal of ground water has considerable 

quantities of dissolved lime, iron and manganese. Abrupt 

changes in pressure and, in some cases, temperature 

conditions in the area in the immediate vicinity of the well, 

coupled with the supply of atmospheric oxygen as a result 


Pic. 2: 

By undersized particle 

blocked filter-slots 

of reducing the water table and microbial activities mean 

that magnesium deposits in the supporting material are 

a well-known problem. This can lead to regular costly 

well cleaning and regeneration measures. If these are 

not carried out or are carried out too late, this can cause 

irreparable damage to the well. As laboratory experiments 

have proven, using glass bead with a smooth surface can 

make it far more difficult for deposits to build up and to 

settle in the annular space. Extending cleaning intervals 

results in a lower financial outlay in maintaining and 

operating the well. 

The additional costs for a well using glass bead instead 

of gravel or sand represents between 5 and 10% of the 

total building costs. If you offset these additional costs of 

building against the anticipated savings to operate and 

maintain the well, the profitability of using glass bead is 

guaranteed, particularly in view of an expected service 

life for a modern well of 30 years.

The acoustic Geo-Scanner: 

an innovative development 

for the industry of 

construction and mining 

machinery 

The successful implementation of construction projects 

and energy-efficient and quality-oriented extraction of mineral 

resources in unconsolidated soft soil depends on a precise 

knowledge about the shape and properties of soil layers. 

Foundation of constructions as well as mineral deposits, e.g. of 

fossil energy resources, industrial and construction minerals, 

are mostly found in the younger sediments of the upper earth 

crust, which consists of layers of cohesive (clay, silt, coal) 

and non cohesive (sands, gravels) materials. Both the stress 

deformation behavior and the hydraulic properties of these 

sediments are significantly different. In particular, the cohesive 

sediments, such as clays, influence the technical feasibility, 

economic viability and overall success of a construction or 

mining project considerably. 

In mining operations one of these layers is the goal of 

extraction while surrounding layers are considered as 

overburden or waste rock. These so called hanging wall and 

intermediate layers are non unproductive and therefore have 

a highly negative effect on the economics of the mining project 

.Usually exploration work has to be executed to get information 

about the underground conditions. The conventional 

technologies provide only selective or spot information and 

do not supply values of quality distribution within the deposit 

or the effectiveness of compliance with a given horizon in the 

underground. The exploration is always a crucial factor in the 

trade-off between efficiency and safety of the project. 

In many construction and mining sites a project accompanying 

inspection of the real subsoil conditions is not or insufficiently 

possible. The use of large open pit mining equipment such as 

bucket wheel excavators, any kind of dredging equipment as 

well as pile foundations in civil engineering are examples. To 

address these issues the Department for Surface Mining and 

International Mining at the Clausthal University of Technology 


22


has developed a system based on an 

acoustic principle - Geo-Scanner - for online 

exploration of soil. The integration of this 

acoustic device at construction and mining 

machinery shall optimize machine design. 

This leads to an increase in economic 

and energy efficiency and environmental 

protection at construction and mining 

projects.

Example for practical use 


23

Function 


The Geo-Scanner is an acoustic scanning device for the 

determination of geogen materials. The acoustic material scanner 

is based on a simple physical principle, the structural borne sound 

behavior of the materials. During the penetration of soil, a typical 

fingerprint of the geological formation is formed as a result of the 

body sound vibration generated by friction. This technology enables 

the online detection of different soil types.

Operating principle from 

idea to implementation

Product innovation 

The product innovation is a development of a simple and robust 

sensor that will deal with the complex requirements and demands 

of the industrial usage and will substitute inadequate visual material 

evaluations. 

The characteristics of the Geo-Scanner are: 

• High mechanical load capacity 

• Weather independency

DETECTINO - 

The Glassy Ground 


Every year, digging causes millions of Euros worth of damage to buried supply lines because in many cases no site 

plans are available. To avoid these costs, the multi-sensor detection system DETECTINO was designed by the Clausthaler 

Umwelttechnik-Institut GmbH, the University of Frankfurt Institute of Geoscience, the machine building company ProKasro 

and the Detectino GmbH. Since 2007 the consortium is working on this versatile, cost-effective mobile device which is 

able to identify buried supply lines in the ground using a DIN-based object-type-key. In addition using differentiated GPS, 

the location and depth of the lines will be determined and plotted into existing cadastral maps with accuracy in the range 

of centimeters. 

Detectino 

The requirements (ground radar 

antennas, metal detectors and 

electromagnetic probes) are installed 

on a mobile platform that is small 

enough for supply line detection 

on footpaths. The sensor system is 

connected to a standard PC which 

transmits the measured data to a data 

base where they are processed by 

new computer intelligence technology 

and mapped into a virtual image of the 

area‘s underground down to a depth 

of 4 meters. Because of the fact that 

this system operates differently from 

conventional systems in an online 

mode, the operator can see the results 

live in a user-friendly 3-dimensional 

visualization and navigate with mouse 

clicks through the underground. So on 

the one hand it leads to the possibility 

to perform earthwork without damage, 

on the other hand it leads to a quality 

control for laying supply lines according 

to regulations and respectively to 

complete cadastral plans. 

The described requirements 

were particularly challenging in this 

project: non-contact sensing, location 

accuracy in the range of centimeters 

using differentiated GPS and provision 

of position and depth information which 

can be used to update existing mapping 

and support 2D or 3D display in online 

mode.

Prototype of the mobile platform with GPR 

antennas - the laptop-screen in detail 


29

Possible target groups for this type of system are: 

• companies that install supply lines, 

• electricity, water, sewage, gas and communications network 

operators, 

• the insurance industry, 

• companies that are responsible for digging up, repairing or 

installing new lines, 

• local government and other agencies 

with a main interest in: 

• more efficient resource planning (personnel and equipment) 

based on knowledge of the situation in the underground, 

• a mechanism to disable digging equipment when it comes 

too close to lines that have been detected, 

• efficient (fast), cost-effective survey of critical or unknown 

areas to assess risks (leaks, flaws, etc.), 


Pic. 3: 

Radargram analysis with computer intelligence technology 

• verification or completion of existing maps, 

• ability to narrow down hazard zones to eliminate or minimise 

damage to existing underground structures during digging, 

• availability of a database which contains topographical 

information and existing supply line networks. 

The development phase and initial field trials show that 

the Detectino system, which uses the latest mechatronics 

technology, IT and geophysical sensors, meets the 

requirements profile, and the use of the device will soon 

be offered as a service. Excavation damage and its costs 

can thus be significantly reduced and implementation of 

effective planing on-site will lead to a huge increase of 

efficiency by using the system Detectino.

LIEBHERR- 

LH 120 C MATERIAL HANDLER 


Specially designed for the movement of bulk materials, the Liebherr LH 120 C material handler makes its first public 

appearance at the 2010 “Bauma” trade fair. Within Liebherr’s extensive material-handling range, this is an entirely new 

purpose-built design. 

LH 120 C MATERIAL HANDLER 

In response to the continual increase in bulk material 

handling worldwide, Liebherr has adopted a new 

approach for the LH 120 C, based on an innovative concept. 

The new machine, weighing approximately 135 metric 

tons, is the result of a development process that takes 

practical material handling requirements into account. 

To emphasise the new development principles that it 

incorporates, a new LH designation has been adopted for 

machines in this series. 

A new design, the high-performance LH 120 C is a 

versatile, cost-effective material handler and therefore an 

interesting alternative for dockside work as well, where 

cranes with a low level of mobility are still being operated 

in many cases. 

The Liebherr LH 120 C material handler 

is powered by a 400 kW (543 hp) Liebherr 

diesel engine. The square layout of the 

crawler-track undercarriage gives the 

machine, which weighs 135 metric tons, 

its high level of stability. 

As on the current generation of 

Liebherr crawler excavators, the LH 

120 C is equipped with Positive Control 

multi-circuit hydraulics, an efficient, 

high-performance system for maximum 

reliability and rapid load handling 

cycles. 

A high proportion of inhouse 

production is a 

guarantee of reliability 

Liebherr components, including the 

engine and the hydraulic pumps, are 

specially designed and rated for material 

handling work, and ensure extended 

operating life and maximum economy. 

The LH 120 C’s multi-circuit hydraulics and its Liebherr 

diesel engine have been matched together for optimum 

results. Lower engine speeds together with hydraulic 

components and hoses of generous cross-section keep 

fuel consumption to a minimum. 

By the systematic use of modular assemblies, both the 

basic LH 120 C and its attachments can be ideally matched 

to operating requirements in specific situations. As a 

result, material handling capacities are high, but costs per 

ton remain low. 

Pic. 1: 

The new designed LH 120 C 


32

Functional machine design, wellplanned 

ergonomics 

Special attention has been devoted to the machine’s 

design in order to optimise its functions while retaining 

well-defined, brand-specific styling features. The LH 120 

C represents a new standard in the user-oriented design 

of large machines, and with its strong brand attributes 

sets itself apart effectively from competitors. 

Equally close attention was paid to ergonomics during 

development of the LH 120 C. All parts of the machine can 

be reached easily and safely by the steps provided. The LH 

120 C also has an entirely new cab that sets even higher 

standards in interior space and operator convenience. 

Windows of generous size provide the best possible view 

of the work and surrounding areas. The cab is so spacious 

that two persons can be accommodated in comfort. 

All the controls are conveniently located within 

the operator’s immediate action radius. A new 

touch screen using an intuitive control principle 

provides a rapid display of all relevant operating 

data. Another feature of this new control concept 

is that the pedals have been kept clear of the 

driver’s field of view. 

Among the notable features contributing to 

Liebherr’s high safety standard are the strongly 

built, convenient access platforms and ladders. 

The cubic body panel outlines make the engine 

compartment easy to reach in safety, and provide a 

roof under which maintenance work can be carried 

out even in poor weather. Large maintenance flaps 

with an electro-hydraulic opening mechanism 

make servicing work even easier on the LH 120 C. 


Pic. 2: 

The new design of the LH 120 C 

Servicing points such as the central lubricating system, 

hydraulic fluid level, engine oil etc. are neatly laid out and 

easy to reach. The fuel tank on the right is exceptionally 

large, so that lengthy work sessions can be undertaken 

before refuelling is necessary. The fuel tank has its 

own integral access steps for easy access without any 

unnecessary increase in the width of the superstructure.

INNOVATIVE SL 750 EICONTROL PLUS 

SHEARER LOADER 


TECHNOLOGY WITH HUMAN TRAITS 

The developed innovative Eickhoff shearer loader is the global solution to safe and highly efficient mining of the 

worldwide most essential energy raw material, the coal, in landscape-saving underground longwalling. A completely 

newly developed automation package targets the power of three Formula 1 racing cars to the coalface while avoiding 

collisions with the surroundings. 

Eickhoff SL 750 EiControl Plus 

Shearer Loader 

NOWADAYS, A MACHINE OF THIS RATING IS CAPABLE 

OF MINING UP TO OVER 1 MILLION TONS OF COAL A 

MONTH! 

Given the harsh mining environment, such production 

rates impose significant challenges on the‚ pilot‘ of the 

mining machine. Up to recently, the machine operator 

being only equipped with a radio control, had to operate 

the machine with all its functions and, like the pilot of an 

aircraft, navigate the mining system three-dimensionally 

through the deposit to be extracted. Dust, rockfall, 

humidity, noise and constraints to the operator‘s vision 

are all grounds for the users‘ demands for far-reaching 

automation of the mining process. Hence the machine is 

expected to automatically orient itself as far as possible to 

the boundaries of the coal layer and to execute production 

autonomously. 

With the automated Eickhoff SL 750 EiControlPlus 

shearer loader it is possible for the first time to realize the 

idea of an automatic longwall operation where men can 

focus on monitoring functions in secure and unencumbered 

surroundings. This leading-edge machine is equipped 

with capabilities of ‚seeing‘, ‚hearing‘ and ‚feeling‘ which, 

all in all combined, are skills only human beings used to 

be capable of, and thus represents a genuine revolution. 

The newly developed Eickhoff SL 750 shearer loader is 

currentily considered as the smartest mining machine 

worldwide. 

The machine state information, the monitoring 

information on the surroundings and the collision hazards 

of the mobile machine, and the information on the position 

of the mining system relative to the deposit boundaries is 

detected by completely newly developed, linked sensors. 

Algorithms evaluate the sensor data and generate control 

information therefrom. The navigation system imparts the 

machine a sense of orientation in the naturally formed coal 

seam. The shearer thus reacts by itself to the continual 

changes of the underground plant requiring adaptation 

of far over 1000 hinges and articulations on every single 

machine pass. 


34

Pic. 1: 

Schematic overview 

Eickhoff EiControlPlus is subdivided into logical partial 

systems which are the haulage automation for the motion 

sequence of the machine and the extraction automation for 

controlling the extraction height and the three-dimensional 

direction of the mining motion. The haulage automation 

automates all motion sequences along the face during the 

extraction pass and includes haulage direction and speed, 

changes in direction, conveyor load protection, collision 

warning and avoidance. The extraction automation controls 

the position of the cutter drums such that the mining 

system autonomously follows the deposit boundaries, thus 

avoiding unnecessary extraction of undesired surrounding 

rock. 

One essential feature of the system is the powerful 

and transparent communication structure between the 

machine and the mine control centre via which all relevant 

information is transferred online through redundant and 

compatible communication paths. 

This unique holistic approach to shearer loader 

automation brings about considerable advantages in terms 

of sustainable extraction of raw material, and of hard coal 

in particular. The Eickhoff SL 750 EiControlPlus shearer 

loader is therefore at the forefront of a machine generation 

which will enable fully autonomous mining systems in the 

future. The operators will then be relieved from the active 


control tasks in the highly stressful surroundings of the 

machine and can focus, from the mine control centre, on 

monitoring and optimization tasks for the system. 

This obviously goes hand in hand with environmental 

and resource protection: Selective mining saves over 1 

million tons of CO2 a year since less surrounding waste 

rock needs to be conveyed to the surface over several 

kilometers on belt conveyors and through shafts. Thin 

seams which are nowadays often unrecoverably left 

behind in a given deposit und thus lost forever, can now be 

mined again in fully automated operations. This concerns 

the majority of the global hard coal deposits. 

This ground-breaking innovation is the result of a 

fruitful cooperation between research and industry. Young 

innovative engineers and highly specialized seniors bring 

in their skills to achieve a long dreamt-of goal. 

Cooperation partners are the machine builder, 

Eickhoff Bergbautechnik GmbH in Bochum, the mining 

company, RAG - Deutsche Steinkohle, and the Institut für 

Maschinentechnik der Rohstoffindustrie (IMR) of RWTH 

Aachen with its spin-off for industrial radar technology, the 

INDURAD GmbH.

OPERATIONS IN SWITZERLAND – 

FROM DRILLING SEDRUN 2 SHAFT 

TO OPERATE WITH TIMDRILLING 

T 

he development of the Thyssen Schachtbau GmbH (TS) Sedrun branch (TS-ZNL 

Sedrun), which led directly to the setting-up of the Swiss-based TIMDRILLING Joint 

Venture, has once again demonstrated that full commitment and dedication at individual 

and team level can drive a successful marketing venture in a new country. 

From drilling Sedrun 2 shaft to operate 

with TIMDRILLING 

Thyssen Schachtbau’s activities in Switzerland 

commenced in 2002 and since then the company has 

been successfully involved in raise-boring and preventersupported 

core drilling work and other specialist mining 

projects. There is no doubt that the high point of these 

operations was the sinking of the 800 m-deep Sedrun 2 

shaft, which was completed within 12 months using a 

shaft boring machine. Some of the planning, transport and 

installation work required for the permanent shaft winding 

system was undertaken in parallel with the shaft sinking 

and was then completed after the shaft touched bottom. 

In order to provide real hands-on support for the 

tunnelling operations and to carry out specialist civil 

engineering and shaft construction work in the Alpine 

regions, most notably in Switzerland and its neighbouring 

countries, three project partners – namely Implenia BAU 

AG (created by the merger of the two Swiss construction 

companies Zschokke and Batigroup), Thyssen Schachtbau 

GmbH and ICOS of Italy – got together to set up the 

TIMDRILLING project group on 06.12.2006. 

The common strategic objective is to develop the TIM- 

DRILLING Joint Venture into a stand-alone company by 

2010.

Market entry with the sinking of the Sedrun 2 shaft and 

installation of the permanent heavy-duty winder 

Issue 01 | 2010 


After lengthy preparations and negotiations the contract to sink the 800 m-deep 

Sedrun 2 shaft was awarded to the Sedrun II Shaft Boring Consortium in March 2002. 

This contracting group comprised RUC (South Africa), TS (Germany) and OESTU- 

STETTIN (Austria). A pilot hole first had to be drilled with an HG 330 raise-boring machine 

before the VSB VI shaft borer could be brought in to excavate the shaft to a diameter 

of 7.0 m. The sinking broke through to the level of the new Gotthard tunnel in June 

2003, an achievement that was due in no small measure to the excellent support and 

cooperation provided by the client, namely the TRANSCO tunnelling consortium, which 

was responsible for the dust extraction, drainage, debris clearance and materials 

supply services.

then taken out to 1.8 m by an HG 330 boring machine. (Photo: Employees TS Group) 

The VS8 VI grits its teeth to 

open the shaft out to 7.0 m.

TS had already supplied and installed 

the heavy-duty winder that was to be 

used for the sinking operation. The work 

subsequently needed to fit out this system 

as a heavy-duty shaft winding installation, 

and the first follow-on contract for 

the servicing and commissioning of this 

machine, provided the basis for long-term 

operations in Switzerland. 

Commercial conditions 

for contracting companies 

working in Switzerland 

Companies wishing to engage in 

business activities in Switzerland first 

have to meet the following conditions: 

• Set up a branch office 

• Arrange for entry in the commercial 

register 

• Register with the taxation authorities 

(for capital gains tax and VAT) 

• Apply for residence and work permits 

for company workers 

The branch office, which was first 

based in Zollikon, was entered in the 

commercial register of Zurich Canton in 

April 2004. The office subsequently moved 

to Sedrun (Graubünden Canton). 

Another requirement for commencing 

operations in Switzerland is that all 

deployed workers must be paid in 

accordance with the collective bargaining 

agreement for the Swiss construction 


39

industry (LMV). While employees’ wages 

and salaries are taxed locally from the 

moment they start working in Switzerland, 

existing social security arrangements 

between Switzerland and the Federal 

Republic of Germany allow any pension 

insurance established in Germany to be 

retained for a period of six years. 

Once the first of the Thyssen Schachtbau 

employees had exceeded this time limit at 

the end of 2008 those concerned switched 

over to the Swiss pension insurance 

scheme on 01.01.2009. This also ended 

all BBG responsibility (German Mining 

Employers’ Industrial Liability Association) 

for these workers, this role then being 

taken over by the SUVA (Swiss Accident 

Insurance Fund), a company under public 

law that is responsible for statutory 

accident insurance in Switzerland. These 

changes, which were a legal requirement, 

also indicate that the TS branch office in 

Switzerland is gradually developing into 

‘real’ Swiss company. 

The conversion to an independent subsidiary is planned 

for the end of 2010. 

Mining expertise in big demand in the 

‘land of the tunnel builders‘ 

A large number of tunneling and specialist civil 

engineering projects, most of which involved work for 

Alptransit Gotthard AG, have been carried out since 

operations commenced in Switzerland in 2002. The initiative 

first developed by TS has in turn been taken over by the 

Sedrun office and TIM-DRILLING. In addition to exploration 

drilling in the Faido and Sedrun sections of the Gotthard 

base tunnels the current scope of operations includes: 

• Preventer-supported rotary percussive and core drilling 

work for preliminary exploration of the tunnel drivage 

• Rotary percussive and core drilling without a pressure 

closing system 

• Conventional and mechanised shaft sinkings, mainly for 

tunnel and hydro electric works 

• Materials and heavy- load transport tasks, installation and 

operation of vertical and inclined conveying installations 

Issue 01 | 2010 


The success of the Sedrun II project was followedup 

by a number of drilling contracts for the tunnel and 

hydropower-plant construction sectors. 


• Installation of infrastructure and supply systems for 

tunnel construction projects 

• Injection work for strata sealing and reinforcement 

In addition to the above activities the permanent Joint 

Venture TIMDRILLING will be providing the following 

specialist civil-engineering services as part of its longterm 

remit: 

• Raise-boring 

• Micro-tunneling 

• Ground freezing 

The TIMDRILLING head office is at Sedrun in 

Switzerland. 

TIMDRILLING project portfolio and future 

prospects 

TIMDRILLING is able to draw on TS‘ expertise in 

shaft-sinking and drilling along with the specialist civilengineering 

knowhow of Implenia Bau AG, with the Italianbased 

ICOS company bringing valuable experience in 

micro-tunnelling and ground-freezing to the overall group 

portfolio. 


40

TIMDRILLNG‘s current activities are mainly 

focused on core drilling and percussive drilling 

work for the excavation of the Gotthard base 

tunnel. The geology, hydrology and geological 

make-up of these sections of tunnel are 

extremely complex and heterogeneous in 

nature. Sophisticated tunneling techniques 

were needed to drive through the fault zones, 

steep and inclined stratification and extreme 

strata overlap encountered along the tunnel 

route, an operation that posed a real challenge 

for the tunnel construction engineers. 

Preliminary drilling was carried out during 

the drivage phase for better geological 

reconnaissance and in order to verify, confirm 

and/or modify the existing prognoses. Thanks to 

recent advances in drilling and strata-injection 

technologies tunnelling engineers now have 

access to preliminary exploration and strata 

reinforcement tools that can be employed 

effectively as the drivage advances. 

TIMDRILLING‘s future not only lies in drilling 

and injection work in the challenging environment 

of the Gotthard base tunnel but will also focus 

on raise-boring and shaft construction projects 

for the Alpine hydro electric industry.

NEW SANDVIK UNIVERSAL BUTTON-BITS 

FOR DRILLING BIG BLAST-HOLES WITH 

TOPHAMMERS 

GREAT VERSATILITy, SIMPLE CHOICES, RATIONAL INVENTORIES, HIGHER PENETRATION RATES, STRAIGHTER 

HOLES, LONGER BIT LIFE AND LOWER ENERGy CONSUMPTION. THESE ARE THE BENEFITS SANDVIK PROMISES 

WHEN ROCK-DRILLERS CHANGE TO RT300 UNIFACE, A NEW AND EXCEPTIONALLy VERSATILE SERIES OF THREADED 

BUTTON-BITS FROM 51-152 MM IN DIAMETER. THANKS TO THE USE OF ONE SUPER-GRADE OF CEMENTED-CARBIDE 

THROUGHOUT AND ONE UNIVERSAL FACE DESIGN PER SEqUENCE OF BIT DIAMETERS, THE USER NEED NOW CHOOSE 

ONLy THE BEST BUTTON SHAPE (SPHERICAL OR BALLISTIC) AND BEST SKIRT DESIGN (REGULAR OR RETRAC) IN 

ORDER TO OBTAIN THE BEST BIT FOR THE ROCK FORMATION IN qUESTION. 

As the leading component in the production chain, the 

drill bit plays a vital role in project advancement and must 

be chosen skillfully and decisively. Today this is hindered 

by a bewildering array of drill bits in the market, which 

can make it very difficult for users to choose exactly the 

right bit for the rock conditions. For any given bit diameter, 

some manufacturers can offer up to ten or more different 

designs. Not only does this make it hard to choose the 

right bit for the job, it also requires the ‘tailored’ bit 

to be changed whenever the rock 

conditions change, if optimal drilling is 

to be maintained. For years Sandvik has 

been trying to clear this minefield by 

consolidating more features into fewer 

drill-bit models in order to widen each 

bit’s range of application. Hardness 

and toughness, two normally mutuallyexclusive 

properties, are just two 

examples of such features. Now the firm 

has announced a double breakthrough. 

The first is XT48, a new grade of 

cemented-carbide that has the highest 

coexistence of hardness and toughness 

ever seen in one and the same tool, 

making it the world’s most universally 

applicable cemented-carbide for rockdrilling. 

The second is UNIFACE, a series 

of three new, patent-protected universal 

bit-face designs, one for Ø 51-64 mm 

bits, one for 70-96 mm bits and one for 

102-152 mm bits. The Uniface design 

combines, synergizes and enhances, 

in a single drill-bit, diverse features 

that formerly necessitated two or more 

different models of bit. To qualify for the 

RT300-Uniface label, a drill bit must have 

both Grade XT48 cemented-carbide 

buttons (indicated by the suffix 48 in the ordering number) 

and a Uniface front. Expected to add value through higher 

productivity, better blasting results and lower rockexcavation 

costs, Sandvik says that RT300-Uniface bits 

will demonstrate quickly the practicality and benefits of 

greater universality.

Choosing the right RT300-Uniface bit 

The guidelines for choosing the right Sandvik RT300- 

Uniface bit are simple: Spherical buttons for very hard rocks; 

Ballistic buttons for less-hard rocks; Regular bit-skirt for solid 

homogenous formations; Retrac skirt for mixed, jointed or 

fractured formations. Thanks to the greater versatility of all 

Sandvik RT300-Uniface bits, however, their respective ranges 

of use are now much wider than before and the changeover 

boundaries are less strict. 

New stepped retrac skirt balances wear and 

eases rotation 

All Sandvik RT300-Uniface ‘Retrac’ bits feature a patented 

new Stepped-Splines Retrac Skirt, which gives the best 

possible hole-straightness and retractability in mixed and/or 

and fractured rock formations. Since the long, splined skirt is 

stepped diametrically, bit rotatability improves immediately. 

In addition, any gage wear to the bit-face and bit-skirt is now 

more synchronous thanks to the steps on the skirt, and the skirt 

always has sufficient gage to provide good guidance in the 

hole. Not only does this improve the long-term rotatability of the 

drill bit, it also reduces wear, cuts energy demands and gives 

better quality holes.

Why the RT300-Uniface design works 

best 

Sandvik RT300-Uniface drill bits combine the best 

features of the former Sandvik Flat-Face series of bits (for 

hard, abrasive rock formations) with those of the former 

Sandvik Drop-Center series (for mixed rock conditions 

and fractured formations). While the new bits exhibit 

characteristics of both designs, notably a combination 

of high, flat surfaces and deep recesses, they are 

much more than just a merger of the two designs. One 

striking characteristic is the high number of buttons in 

the face, as well as their more optimal placement and 

larger dimensions, which means that more hard-metal 

is presented to the rock more strategically and more 

efficiently. 

The foregoing features assure greater efficiency, 

higher productivity, straighter holes and less wear. As a 

result, more blast-holes of better quality can be drilled 

more economically in less time using less energy.

KIESEL delivers Hitachi EX1200-6 

to MSW in Moensheim 

Pic. 1: Satisfied partners: (from right to left) 

Stefan Kunkel (operations manager, MSW Mineralstoffwerke Südwest), Heinz Albert Mertz (CEO MSW), Alexander Tress (Kiesel Ungeheuer 

Leonberg), Manfred Prinz (sales manager, Großgeräte Kiesel/Baienfurt), Helmut Scherhaufer-Kremmer (CEO, LOC-matic). 

CRYPTOGRAPHIC EqUIPMENT IN DIRECT MINING 

A NEW HITACHI EX1200-6 STARTED ITS OPERATION IN THE MOENSHEIM qUARRy OF THE MSW MINERAL FACTORy 

TOWARDS THE END OF OCTOBER. THE 120 TON EXCAVATOR WITH BACKACTOR EqUIPMENT MINES UPPER SHELL 

LIMESTONE WITH THE TEARING-/LOADING-INITIATION. IN THE MSV STONE FACTORy AND ITS ADJACENT ASPHALT 

PRODUCTION, THE UPPER SHELL LIMESTONE IS PROCESSED INTO ROAD CONSTRUCTION MATERIAL FOR THE GREATER 

STUTTGART AREA AND THE NEARBy UPPER RHINE REGION KARLSRUHE/BADEN-BADEN. 

APART FROM THE PERFORMANCE OF THE EX1200-6, PARTICULARLy THE CUSTOMER SUPPORT OF THE REGIONALLy 

RESPONSIBLE KIESEL-UNGEHEUER COMPANy CONVINCES THE COSTUMERS. WITH THE OPENING OF ITS DISTRIBUTION 

AND SERVICE BRANCHES, THE COMPANy HAS JUST LASTINGLy INVESTED IN THE COSTUMER SERVICE OF THE REGIONS 

STUTTGART AND NORTH-WUERTEMBERG. 

Shell Limestone for the Entire Region 

The Moensheim quarry, which has been in operation 

since 1978, is the lead plant of the MSW Mineralstoffwerke 

Südwest GmbH & Co. KG, a hundred percent subsidiary 

company of the Heinrich Metz company, with its 

headquarters in Stuttgart. The medium-size enterprise that 

is being lead by Albert Mertz almost in its fourth generation 

and with its own plants and shares, has been nationally 

active for over 80 years in the rock extraction, construction 

material production and logistics. 

Apart from shell limestone, the Mertz-offer also includes 

sand and gravel deliveries by road, train or ship from the 

Rhine valley, regional ready-mix concrete and asphalt 

plants, as well as handling of old-building material. Thanks 

to the easy access, the approximately 300,000 tons of 

the MSW annual production from Moensheim reach a 

nationwide market: Located immediately at the A8 between 

Pforzheim and Stuttgart, Moensheim supplies the entire 

Stuttgart conurbation, as well as the upper Rhine regions 

Karlsruhe and Baden-Baden, due to the economic gravel 

return freights from the Mertz partner company. 

Currently the open wasting asset in Moensheim accounts 

for 4.5 hectar, in which upper shell lime stone with a depth 

of 25 -50 m is mined in wall heights of 5 meters, free of 

blasting. A large excavator with a backacter boom and a 

combined tearing-/loadingbucket is used, and two 60 ton 

steep-dumper trucks transport the rocks approximately 100 

meters to the primary crusher of the 300-t/h processing. 


45

According to the leader of the operation Stefan Kunkel, 

the deposits in the current mining area will last for another 

one and a half years, after that the MSW will mine into the 

south direction, since the deposit still has a license for 

operation for the next 25 years. After that the cycle become 

considerably longer, which increases the demands to the 

cryptographic equipment extraction excavator and thus 

creates new possibilities for a tailored adaptation of the 

processing capacities. 

Issue 01 | 2010 

Abb. 2: 

The broad reach of a maximum of 13.75 m allows for an economic 

tearing-maneuver without frequent relocations. 

“After nine years and approximately 2000 operating 

hours, the service balance of our 120 ton machine rapidly 

deteriorated. Not only wearable parts and service costs, 

but only minor downtimes quickly have a negative effect 

on the organization of our one-shift operation.” This is how 

Stefan Kunkel outlines the change of demand, which at 

the end of last year led to a tender for new cryptographic 

equipment. 

High-performance Dredger Concept 

Apart from making inquiries from its previous suppliers 

and service partners, MSW made inquiries from other 

suppliers in the 120 ton category, too. This also included 

Kiesel, which is the exclusive German partner of Hitachi. 

Parallel to the construction of its area-wide distribution 

and service systems in construction engineering, Kiesel 

has lastingly positioned itself in intensive project support 

of giant equipment in the mining segment. 


Apart from the Hitachi steep-framed-dumper and the 

growing Zaxis- wheel loader family, which currently is 

mainly used for the reclaiming and dumps cultivation 

of non-metallic mineral processing plants, the German 

mining industry is mainly interested in Hitachi Hydraulic 

excavators with a charge weight of 50 to 120 tons. Hitachi 

responds to this by covering all typical service types in the 

German open pit mining with five well graded types from 

its quarry and mining program with its models of up to 800 

tons charge weight. Furthermore, together with its delivery 

partner Kiesel, it adapts itself to customer-specific needs

in the company organization, thanks to comprehensive 

options of its ZX- and EX models. This includes both 

loading-geometry of face-shovel and back-hoe dippers, 

down to the 50 ton model Hitachi ZX470, as well as special 

rock equipment for driver’s cabs and undercarriages. 

The Hitachi EX1200-6 is the smallest of the original 

Hitachi-EZ-mining excavator family. Since its introduction 

in 2005 Kiesel has already managed to place 8 machines 

of the 120 ton excavators, mainly in mining operations of 

the natural rock and chalk industry. Hereby, for the first 

time in Moensheim, a version of the current 6th generation 

back acter was applied. This version ensures a quick and 

highly productive loading operation through an optimized 

hydraulic function, while ensuring a long service life 

by targeted improvements in undercarriage, rotating 

assembly and drive chain. The new cabin and numerous 

improvements in operation and security, which further 

simplify operation and maintenance, also contributes to 

the improvements. 

The 567-kW strong Hitachi EX1200-6 with its 7.55m BEside 

arm and 3.4 m BE-upright is in operation in Moensheim 

on a 4.60m wide undercarriage with a slab width of 700 mm. 

Since mining and truck loading in the MSW operation are 

often done on the same bed, the back acter excavator has 

been equipped with a cabin elevation, which offers the best 

view into the charging box through the 1.1 m heightened 

position of the driver and also simplifies the work at the 

wall. The plant management opted for a 6.2 m 3 rock ripper 

bucket HDTL 84-S of the LOC-matic from the Alershausern 

Issue 01 | 2010 


delivery partner of Kiesel, to be applied as the high-wear 

tearing-/loading-application. The 9.8 t shovel has good free 

punch characteristics, which ensures high penetration 

and filling momentum. Its specific construction and highstrength 

material make the shovel buckling resistant and 

thus enable full utilization of the high breakaway torque 

and tear-out force of the Hitachi EX 1200(according to 

ISO: 569 kN and 438 kN respectively). The 75SV2 system 

of the Kiesel equipping partner Esco, which is particularly 

designed for hard rock demands, is being used as sprocket 

system. 

Having Invested in Service 

The Stuttgart branch of the regionally in charge Kiesel- 

Ungeheuer company, located in the 15 km far Leonberg, 

was in charge of the project. “The proximity and good 

communication and cooperation with all involved technical 

experts of the Kiesel- head office and Hitachi has certainly 

also been a decisive factor”. This is the resume of the 

operation manager Stefan Kunkel regarding the decision 

of opting for Hitachi for the cryptographic equipment in the 

plant. “We assume that, in case a quick service reaction 

ensures the availability of our mining excavators, this will 

further pay off in our operation.” 

Pic. 5: 

Kiesel delivery partner LOC-matic contributed 

the rock ripper bucket HDTL 84-S, which ideally 

converts the high loading force of the back-hoe 

dipper with specific geometry and high-strength 

material. 


47

The long-term basis for this has been created 

by Kiesel-Ungeheuer with high investments in 

Leonberg. It was only at the end of this year that an 

administrative and service building was inaugurated 

(approx. 6.000 m²), which concentrates the customer 

service and service capacities of the “Swabian” 

Kiesel-Ungeheuer branch. Beside the two locations 

in the Baden region, Karlsruhe and Mannheim, 

Leonberg is in charge of the regions Middle Neckar, 

Ostalb and Hohenlohe. Like all other nationwide 

branches and bases, which currently amount to 32, 

the new branch is fully integrated into network of the 

Kiesel-group. This ensures quick access to technical 

information from industry-sector and machine 

specific centers of competence on one hand, and 

on the other hand quick mediation of services for 

repair and maintenance or in the leasing area.

CDE Ireland Ltd, Cookstown, North Ireland: 

CUSTOMISATION – 

THE ROAD TO SUCCESS 

Issue 01 | 2010 


Lafarge are enjoying increased efficiencies at their Brooksby quarry following the introduction of a turnkey 180tph 

sand and gravel washing plant from Northern Ireland company, CDE Ireland. The plant has recently completed final 

commissioning and initial tests on the final products show a considerable improvement in quality when compared to the 

previous processing system being used at the site. 

Brooksby quarry is located near Melton Mowbray 

is Leicestershire and is a relatively new addition to the 

Lafarge portfolio having opened for business in 2007. The 

company has a licence to extract 300,000 tons of sand and 

gravel at the site, which at current capacity will allow for 

fifteen years production. The site will be progressively 

restored as extraction progresses to become agricultural 

land and a complex of lakes. 

The sustainability agenda is one that Lafarge take 

very seriously, as can be seen by their membership of 

seventeen wildlife trusts in the UK alone. While Lafarge 

are recognised as one of the most prominent names in 

the global construction materials market, their work in the 

UK is characterised by a commitment to local community 

groups and initiatives. 

“We rely on the local communities we serve in many 

ways” explains Andy Morris, National Production Manager 

in the UK with Lafarge. “Lafarge Aggregates have over 

200 sites throughout the UK and the vast majority of these 

operations are managed on a day to day basis by people 

from the local area.” 

In addition to the 200 sites operated by Lafarge 

Aggregates in the UK, the Lafarge group also operate 

30 recycling centres processing a variety of materials 

including used rail ballast, concrete, asphalt, bricks and 

other demolition wastes. 

A new solution 

Pic. 1: 

Plant at Brooksby quarry 

Lafarge opened discussions with CDE about a new 

washing plant at Brooksby in late 2007 as a result of 

difficulties being experienced in processing the natural 

sand and gravel at the site. “The presence of clay in the 

raw feed was proving to be a problem with our previous 

processing system and this was having a significant impact 

on the quality and commercial value of our final products” 

says Andy Morris. 

A key factor in the selection of CDE to provide the 

solution to this problem was the customisation of the plant 

to the specific characteristics of the feed material. “We 

had gone down the off the shelf route before and it had not 

been successful” explains quarry manager at Brooksby, 

Will Laycock. “We set very high standards in relation to 

final product quality and these standards dictated that we 

sought to address the issues raised by the level of clay in 

the feed material.” 


49

Tackling this issue began with detailed materials testing 

at CDE’s laboratory in Cookstown. A substantial quantity of 

material was analysed in order to gain a clear picture of 

the typical grading the plant would be required to process. 

Once this had been determined CDE’s technical design 

engineers began to build the plant in order to produce the 

final products required by Lafarge – in this instance three 

aggregates and two sands (coarse and fine). 

Lafarge were able to provide CDE with detailed 

information on the grading of the final products that were 

required and from this the constituent parts of the plant 

were adapted to produce the required results. “Lafarge had 

a very clear idea of where they wanted to go and this helped 

enormously when we worked on the plant configuration” 

explains CDE’s general manager in the UK, Terry Ashby. 

Given previous experience at the site Lafarge were also 

keen to include a number ofperformance guarantees 

with the order for the new washing plant. These covered 

gradings for all the final products and the lagoon water, as 

well as the final moisture content of the sand products. 

“The introduction of the performance guarantees on 

the plant was a critical factor for us in order to ensure 

that this considerable investment delivered the required 

results” says Andy Morris. “We were very impressed with 

CDE’s willingness to work with us on these guarantees. It 

demonstrated a level of confidence in their capability that 

is not the norm in our experience.” 

Issue 01 | 2010 


A key factor for CDE in accepting the performance 

guarantees requested by Lafarge was the level and clarity 

of information made available to them prior to the deal 

being done. “With access to the amount of information 

provided by Lafarge we were able to produce a large 

amount of data outlining what our plant would achieve” 

explains Dermot Murphy of CDE’s technical specification 

team. “Over the last seventeen years we have continually 

analysed plant performance and made design adjustments 

where required. We know what our plants are capable of 

and this confidence allows us to enter into agreements 

around final product specification such as the one agreed 

for the Brooksby plant.” 

Plant set up 

Pic. 2: 

Feed hopper which feeds a 

horizontal ground conveyor 

The final plant configuration installed and commissioned 

by CDE at Brooksby quarry draws on a range of equipment 

from the CDE portfolio – hoppers, conveyors, ProGrade 

screens (both rinsing and dry sizing screens are included), 

the new AggMax attrition and classification system, and 

an A-series Evo-Wash sand plant. 


50

Pic. 3: 

Stockpile conveyors 

The feed material is loaded into the feed hopper which 

feeds a horizontal ground conveyor. From here the material 

is then transferred to a 28m static feed conveyor on its way 

to the primary screening phase. Due to the levels of clay 

in the feed material the conveyor is fitted with scrapers 

to ensure the belts stay as clean as possible, minimising 

spillage and ultimately increasing plant efficiency. “We 

offer a range of options to customers based on the individual 

requirements of the project” explains Terry Ashby. “The 

characteristics of the feed material are often the most 

significant consideration and by having a menu of options 

available, it ensures we can deliver high performance, high 

efficiency installations.” 

At the primary screening stage a ProGrade R211 double 

deck rinsing screen is employed and is set up with two 

polyurethane decks. The screen measures 6 m x 1.8 m 

(20 x 6 ft). The oversize (+ 40 mm) material is discharged 

into a concrete bay beneath the screen while the -5 mm 

material and waste water are sent to the EvoWash sand 

plant. 

The 5 mm to 40 mm material is delivered directly to the 

new CDE AggMax system. This unit combines the RotoMax 

attrition system and ProGrade dewatering screens in a 

compact configuration that reduces the space required 

on site to accommodate the plant. The RotoMax system 

has been introduced to specifically tackle the level of clay 

in the feed material. The model at Brooksby, the RX100, is 

one of three models available from CDE, with the largest 

capable of handling up to 300 tph. The RotoMax uses high 

specification components such as 118 chrome molybdenum 

blades, and has been designed to ensure maximum attrition 

of clay bound materials. The waste water from the RotoMax 

is sent to the EvoWash sand plant to recover any of the -5 

mm material that made it past the first screening stage. 

Meanwhile, the scrubbed +5 mm material is delivered 

Issue 01 | 2010 


from the Roto-Max onto a ProGrade C-series de watering 

screen before being sent to the dry sizing screen via a 20 

m static transfer conveyor. The dry sizing screen on this 

plant is a ProGrade D26 double deck screen measuring 

4 m x 1.5 m (13 x 5 ft) and once again set up with two 

polyurethane decks. The dry sizing screen classifies the 

products into 5 - 10 mm, 10 - 20 mm and +20 mm aggregates 

which are transferred to stockpiles by three 20 m static 

conveyors. “The use of high specification components can 

be seen throughout the plant” says quarry manager, Will 

Laycock. “We had some fairly tight guidelines for CDE in 

terms of what we expected from the plant and in order to 

achieve this it was essential that we took the quality route. 

CDE have demonstrated the benefits of this approach in 

relation to product quality and efficiency and the results 

being achieved speak for themselves.” 

At the sand washing phase an A-series EvoWash sand 

plant is employed and produces a coarse sand and a fine 

sand. The specification of each of these sand products 

is covered by the performance guarantees discussed 

previously, as is the moisture content of both final sand 

products. The EvoWash sand plant has a 4 m x 1.8 m (13 x 6 

ft) polyurethane screen deck which is split to allow for dual 

sand production. The slurried waste water and -5 mm sand 

product is delivered to the sump of the sand plant where it 

is then pumped through the first of two 500 mm cyclones. 

The material is then discharged onto the first side of the 

split screen where the aperture is set to allow the fine 

material to fall through to the sump with the waste water. 

The coarse sand product is dewatered on the screen 

which is powered by two 9 kw high frequency vibrating 

motors. This ensures maximum dewatering of the sand 

product, ensuring it is ready for market straight from the 

belts. The fine sand material is then pumped through the 

second of the 500 mm cyclones. The -63 micron material 

and waste water is removed via the cyclone overflow and 


51

sent to a ground sump in close proximity to the sand plant. 

This material is then pumped to on site lagoons. The fine 

sand product is delivered to the second side of the split 

dewatering screen where it is dewatered to approximately 

12 % moisture content, once again ensuring it is ready for 

market straight from the belts. 

Conclusion 

The new CDE washing plant at Brooksby quarry has 

succeeded in addressing the specific issues identified 

by Lafarge as being critical to plant success. The system 

successfully deals with the clay content in the feed 

material to produce the high quality sand and aggregate 

products demanded by Lafarge to uphold their reputation 

as a leading supplier to the UK market. In addition to this, 

the superior dewatering of the sand product in particular 

allows Lafarge to quickly turn their products into revenue. 

The installation and commissioning of the Brooksby 

plant was delayed following an unforeseen discovery of 

archaeological significant materials on site in mid-2008. 

“During preparation for the plant to be delivered to site 

we discovered materials later revealed to be from the 

Palaeolithic period” explains Will Laycock. 

Issue 01 | 2010 


“This required some adjustments to the location of the 

plant and held up proceedings for a number of months 

while detailed investigations were carried out on site. 

Throughout this process and actual installation and 

commissioning we were very impressed with the project 

management approach adopted by CDE.” 

The new CDE plant at Brooksby quarry provides evidence 

of the success that can be enjoyed on projects such as this 

when a partnership approach is taken by both the customer 

and equipment supplier. A high level of consultation in the 

plant design process ensures the objectives of the plant 

are clear to all involved, maximizing the likelihood of an 

efficient, high quality installation.

Zeppelin Baumaschinen GmbH: 

THE CONSTRUCTION MACHINE AS A NETWORKER! 

ZEPPELIN AND CATERPILLAR PRESENT INNOVATIVE 

SOLUTIONS IN THE AREA OF CONNECTED WORKSITE 

IN BAUMA 

G ARCHING, NEAR MUNICH, IN JANUARY 2010 (ZEP/AB). ALREADY THE DEMANDS OF COSTUMERS OF CONSTRUCTION 

MACHINES CANNOT BE COVERED BY THE CLASSICAL PRODUCT AND SERVICE RANGE. THERE IS A NEED FOR A 

SYSTEMS SOLUTION, WHICH OFFERS THE CONSTRUCTION COMPANY A MAXIMUM OF ACHIEVED WORK WITH A 

MINIMUM OF INPUT, WHILE MAINTAINING A MAXIMUM OF FLEXIBILITY. THE SOLUTION LIES IN THE THEME COMPLEX 

„CONNECTED WORKSITE“ – A FIELD IN WHICH CATERPILLAR AND ZEPPELIN ARE INNOVATION LEADERS. 

In connection with construction machines, “Connected 

Worksite” stands for integrated application of GPS- 

determination of position, machine control, diagnosis 

and maintenance planning, consumption and productivity 

monitoring, as well as protection against theft. The sole 

application of these technologies yields significant 

productivity increase. Considering all machines, 

“Connected Worksite” mainly means the informational 

linkage of machine fleets with the construction site 

management and the central departments. It is only then 

that the full potential of the new technical possibilities can 

be tapped. 

Cat construction machines can already be equipped 

with the products „Product Link“ (tracking, equipment 

condition monitoring, plant maintenance planning), as well 

as Accu Grade and CGC Caterpillar Grade Control (machine 

control). Special products from the mining fields, like CAES 

or MINGEM complete the range of products. Furthermore, 

additional technologies like for example technologies 

for identification of objects and the remotely controlled 

application of construction machines are already being 

developed. A further focus is on the construction site 

and fleet management systems. The systems Minestar 

(applications planning) and Remote Operation (control 

station and remote control technique) are being applied in 

numerous mining operations. The new fleet management 

system Vision Link, as well as other systems for the 

complete automated application of construction machines 

are currently under development. 

The newest generation of the Cat construction machines 

is being prepared for the application with Connected 

Worksite products in the production line. In order to track 

and position the working equipment, e.g. a dozer, only a 

GPS receiver is needed, together with an angle sensor, 

which determines the inclination of the machine. Together 

with the information determined by the hydraulic cylinders 

and transferred to the computer, any position of the 

blade can be aimed at in a fully automated way. The fleet 


53

management components, which are integrated in the 

machine, record the location of the machine via GPS and 

also record numerous situation data through sensors. The 

data transfer to the construction site control center or to 

the IT systems of Caterpillar and Zeppelin is either done by 

mobile phone networks or by communication satellites. In 

order to communicate with each other and with the control 

center, the machines on the construction site are equipped 

with radio data transmission, which enables a bidirectional 

transfer of data. 

A system for all Machines 

Through its cooperation with Trimble, which is clearly 

the global market leader for positioning and measurement 

technologies, as well as for construction site management, 

Caterpillar has systematically aligned its own machines to 

Connected Worksite. Thus the company developed CTCT, 

a 50:50-Joint Venture, which comprises of the product 

lines GCS (Trimble) and AccuGrade and CGC (Caterpillar), 

respectively, in order to control construction machines 

through laser-, GPS- or tachymeter systems. Last year both 

partners established another joint venture company. From 

now on Virtual Site Solution takes care of the development 

of construction site and fleet management systems. 

The strategic partnership with Trimble enables Caterpillar 

to integrate special technologies into the machine 

development already at the design phase. Moreover, 

through the integration of Trimble products, Caterpillar 

also creates the prerequisites for costumers to manage 

mixed fleets with a system family. Thus the construction 

site and fleet management systems of Trimble can both

The newest generation of the Cat construction machines, like the dozer D6T, is being prepared 

for the application with Connected Worksite products, already in the production line. 

process the machine data of Caterpillar and Non-Caterpillar 

machines, and hence the costumers are not forced to use 

parallel systems from various manufacturers for their 

machine management. Furthermore the construction site 

and fleet management systems can transfer machine and 

performance data to the ERP systems of the costumers 

through standard intersections. 

Apart from the actual products, the competence in 

distribution and most of all in service, in connection with 

Connected Worksite solutions, are critical for the costumer. 

Together with the power spectrum of Zeppelin and Trimble, 

Caterpillar has unique offers. Its machine design, which 

already takes into consideration the integration of various 

technologies, combined with a service offer, which 

includes the required engineering knowledge, enables the 

costumer to achieve a maximum of work with minimum 

input and high flexibility. 

More information on the subject of Connected Worksite 

can be obtained by the visitor to the bauma 2010 at the 

Zeppelin and Caterpillar booth in Hall B6.

PFREUNDT GMBH – MOBILE WEIGHING SYSTEMS 

he market leader for mobile weighing systems for the mining, disposal and recycling industries once again 

Tpresents its new p-series wheel loader scales and weighing systems for dumpers, excavators, crusher and 

sifting plants and skip containers to its customers, dealers and interested parties - on two BAUMA stands. The 

main stand can be found in Hall A6 opposite the information desk, as in the past, and the smaller info stand is in 

Hall C2 in the mining section. 

Pic. 1: 

Ludger Wissing, Managing Director of Pfreundt GmbH, 

sees growth potential for mobile weighing technology and 

the company’s services on the back of the new p-series 

wheel loader scales. 

For over 30 years, the scales manufactured by the specialist from Südlohn have enabled thousands of local 

and foreign users to reduce costs, optimise operations and save time and money. The scales furthermore 

increase safety by preventing vehicle overload. 

Savings potentials – in demand also in times of crisis 

The mobile weighing technology by Pfreundt is a permanent component of material and information flow 

already in numerous mining, handling, disposal and recycling operations. Especially in the past crisis year, 

many companies have been looking for ways to rationalise and manage material flow more efficiently – in 

this respect, mobile weighing technology can offer many optimisation and savings potentials. It is thus not 

surprising that Managing Director Ludger Wissing sees the potential for further growth of the company.

Issue 01 | 2010 


Pic. 2: 

This is what it will look like – the new business complex comprising warehouse, workshop, training and seminar 

rooms and a generous vehicle hall are expected to be ready for occupancy in the second half of 2010. 

New buildings – growth and service 

expansion require space 

“Our consistent growth demands additional space for 

development, administration and manufacturing. And 

we also require more space for our extended range of 

services”, says Wissing. Last year, despite the general 

crisis mood, the company started with building operations 

for a new business complex. The larger office, warehouse 

and workshop space and also the training and seminar 

rooms and a generous vehicle hall are expected to be 

ready for occupation in the second half of this year. 

New »pSerie« – 

modern wheel loader scales to meet 

present and future demands 

The new p-series wheel loader scales extend the range, 

adding to the WK50 series models that have been tested and 

proven in over 10 000 applications. The modern pSmart and 

pControl electronic displays are more compact and offer 

a new, ergonomic user concept. They can be calibrated 

to meet the Y(b) accuracy class under MID and optimised 

weighing methods ensure additional improvement when 

weighing whilst the loader is in motion. 

pSmart is a simple display and control unit with all 

the basic technical weighing functions for calibrated 

applications. It is easy to use since the scale guides 

the user with clear symbols and no text instructions are 

required. 

pControl is fitted with a functional jog dial. Augmented 

by intelligent input aids and options for individual settings, 

operation is quick and easy. The new colour display of 

the pControl is also optimal as a monitor for a reversing 

camera – saving space and increasing safety. 

The weighing intelligence of the p-series is located in the 

pBase – a new functional unit. Hydraulic pressure and tilt 

are measured here and weight is calculated and weighing 

data stored in the alibi memory. pBase communicates with 

the pSmart or pControl displays via CAN bus and can be 

calibrated via these. 

Pic 3: 

»pControl« – the robust control centre for quick control, 

with interfaces for data transfer and up to camera port. 


56

The new p-series can naturally also be cost-effectively 

retrofitted to other wheel loaders and the complete display 

module, the printer and even the new pressure sensor 

are replaceable within a calibration period if necessary – 

without recalibration. 

Another novelty: the associated “pOffice” PC software. 

Weighing and master data can be exchanged between 

the PC and pControl using either USB stick, GSM, GPRS 

or WLAN. This also enables online linking of the scales for 

order processing. 

Consistently positive feedback by the first users confirms 

that the manufacturer’s objectives have been achieved: 

simple operation, better overview, faster working, accurate 

weights, up-to-date options, increased reliability. 

Further novelties and developments 

Besides the p-series, visitors will also find information 

on numerous product improvements and extensions and 

other new developments such as the new DW-3 dumper 

scale for articulated dumpers. Compared to the DW-2 

scale which remains on offer, the DW-3 establishes the 

weight of the load via measurement sensors on the swing 

axle already during loading. The loading status is shown to 

the driver of the excavator or loader via the green-yellowred 

colours of the connected signal light - to prevent 

overloading.

Service – everything under one roof for 

maximum customer benefit 

Since the founding of the company, the scale specialist 

has made “made in Germany” product quality and 

customer-oriented service expansion his guiding principle. 

The company can today offer its customers services 

ranging from assembly support and conformity assessment 

to customer and calibration service – all under one roof. 

Under the new MID certification, the scale specialist 

now also performs the “first calibration”*) of the wheel 

loader scales without a calibration officer – saving 

time and money. The calibration service has also been 

extended to four company calibration trucks on German

oads - to handle conformity assessment, calibration and 

re-calibration. “Calibration authorities previously handled 

the first calibration but these are increasingly doing away 

with their own standard weights. We are certified in 

accordance with the MID directive, allowing us to perform 

our own first calibration*)”, says Ludger Wissing. 

[*) technical term: “Conformity assessment”] 

Further expansion of global distribution 

With agencies and branches in 38 countries, the company 

is also well placed in respect of global distribution. Together 

with its distribution partners, the scale specialist currently 

serves dealers and customers throughout Europe and in 

many other countries in the Americas, Australia and China. 

Issue 01 | 2010 


Pic 8: The Pfreundt service department performs the first calibration*) of the 

wheel loader scales without a calibration agency official. 

This means increased flexibility, saving time and reducing costs. 

Pic 9: Geared towards growth – to expand its services the company has 

acquired two additional calibration trucks, among other. 

New partners in Peru, Romania and Bulgaria have recently 

been appointed distributors for the German manufacturer 

and the “DISA” company in Sarnen (Lucerne) in Switzerland 

is also now a distributor. Besides our 11-year-old branch 

in Italy, another subsidiary was last year established in 

Croatia. Registration of a further subsidiary in Sweden 

is currently under way and negotiations are in progress 

about possible representation in Turkey. 

Competent advice and customer-oriented service are 

our guiding principles both locally and via the agencies 

and branches abroad. Regular training and dealership 

conferences are held to achieve this goal, keeping technical 

and sales staff of all the partners technically up to date and 

also identifying and implementing improvement potentials 

through global exchange of information.

BSW Stahl-Nebenprodukte GmbH 

simplifies the flow of information 

of weighing data 

The Baden steel works (BSW) in Kehl at the river Rhine 

are one of the highest-performance steel works in the 

world and produce over 2 million tons of concrete steel 

and wire rod for Europe. It only takes four hours to turn 

steel scrap as initial raw material into the ready-for-sale 

product – a peak value. 

In marketing of its side products, BSW also focuses 

on high efficiency. The sister company BSW Stahl- 

Nebenprodukte (steel side products), in short BSN is 

responsible for this task. It produces mineral material for 

the construction of traffic routes from electric furnace 

slag, which after all amounts to approx. 350,000 tons per 

year. 

Electric furnace slag- a high-quality and 

versatile mineral material 

The electric furnace slag, which is being marketed 

in all established grain sizes by BSN as “EOS”, can be 

universally used. EOS can be used in road construction 

in all layers, i.e from the anti-freezing and ballast layer 

up to the asphalt coating. Furthermore the material is 

extraordinarily suitable for the hydraulic construction, as 

well as for road building and road coating. EOS can also

be applied as filling material of gabions, which serve as 

noise- or visual protection. Hereby the usage of mineral 

construction material preserves natural resources. 

Efficiency of material and information flow is an important 

indicator in the BSN- factory premises. A few minutes after 

the weight note for the material – which is being loaded on 

the trucks by 5 wheel loaders - is printed, the materials 

and accounts department of the BSN administration is 

informed about the exact amount. 

Mobile weighing technique saves time 

For over 10 years, the wheel loaders have been equipped 

with weighing systems of Pfreundt. Specific pressure 

sensors in the hydraulic actuator of the wheel loader 

register the weight of the bucket contents and transfer the 

measuring data to the WK 50-weighing electronics, which 

is located in the cockpit of the construction machine. 

Through an amount display the driver can load exactly as 

much material as the costumer wishes. 

Through this it is possible to effectively avoid both an 

overloading of trucks, as well as too high, uncalculated 

loading amounts, due to the fact that work is done 

“according to gut-feelings”. The way or detour to a

stationary weighing scale also can be dropped. After the completion of the loading, the 

driver of a wheel loader prints copies of a weighing card, containing the costumer-, 

order and/or project number. The driver of the collecting truck receives this weighing 

receipt “in writing”, acknowledges receipt and can immediately start his way to the 

construction site.

WLAN instead of memory card 

Up to a few months ago BSN stored the weighing data 

on an integrated memory card, which was handed over 

each evening and was read in and processed by the BSN 

administration the next day. A few months ago a modern 

and quick solution was developed in collaboration with the 

IT specialists of the BSW group. Daniel Baumgart, leader 

of EOS production with BSN says: “ Simultaneously with 

the print, the weighing data are sent via WLAN from the 

weighing electronics WK50 to the administration” 

Increased efficiency and informational 

advantage 

With this solution the memory card can be omitted, 

which simplifies the operation, increases the transparency 

and creates the basis for a quick information flow from the 

wheel loader weighing scale to the company software for 

materials handling and financial settlement. It is not an 

issue that the data transfer is actually done in real-time: 

actually there is no need to be that quick. But the automated 

procedure of the handling of the weighing data saves 

both time and efforts. Furthermore additional information 

is available at a keystroke. Daniel Baumgart states: “ In 

bigger projects the colleagues in the administration, as 

well as we in the operation can immediately see how 

much material has been loaded in a 3000 ton order. With 

the incorporation of the mobile weighing technique into 

the company IT, BSN puts into practice not only a gain in 

efficiency, but also an information advantage.

MOBILITY ON HOLD 

STATIONARY WORKAROUND PREVENTS RISKY MANEUVERS IN qUARRY: 

A t the Kuhn Quarry near Waldhambach at the Pfälzer Wald Nature Reserve, granite and andesite have 

been extracted to produce ballast for many decades. At the quarry, mainly granite is extracted for 

the production of ballast base and frost protection courses, though some armourstone is won, part of 

which are used for landscape gardening. In the natural fissures of the andesite, agates, for example, are 

formed, attracting the interest of dedicated mineral collectors. 

A quarry facing big changes 

Since the physical partition of the fraternal 

company partnership in 2006, the quarry itself 

has been facing massive changes. Willi Kuhn and 

his son-in-law Stefan Kuhn, who has taken over 

management since the restructuring of the company, 

developed a new operating concept and set up a 

double separate production circuit. For this purpose, 

two large intermediate storage facilities with tunnels 

and metering equipment were set up. The aim was to 

maintain the operating cycles without any interruption 

– irrespective of whether the primary crusher is being 

maintained or whether one of the screens happens to 

be down in the modernized screening facility. Looking 

ahead and with the purpose of increasing productivity,

from the mobile Lokolink 

conveyor to the stationary belt 

it was necessary to scrutinize the individual machine 

components. The aging stationary primary crusher had 

to make room for a mobile unit, to enable a more flexible 

extraction process. 

In 2008 the operators opted to invest in a mobile 

Lokotrack LT140 supplied by Metso Minerals, to which 

a mobile conveyor, the Lokolink LL, can be connected. 

Prior to this, the company had been able to convince itself 

of the efficiency of Metso’s second-largest mobile jaw 

crusher and then set itself the objective of more flexible

production with the new unit and above all directly at the 

pile of blasted rock. Previously two large excavators and 

two dumpers worked at the sites to extract the andesite 

and granite, requiring a total of four operatives. Thanks to 

investment in a mobile jaw crusher, the company hoped 

that it could save on three operatives as well as three large 

machines in the quarrying operation, which were in future 

to be freed up for overburden and backfilling work. This 

was initially a very expedient decision as one excavator 

operator can deal with operation of the Lokotrack at the 

same time.

Feeding process at the bin 


Stationary feed for a mobile unit 

On account of the steep slope and sometimes difficult 

space conditions, following the acquisition, problems 

arose with the manoeuvrability of the primary crushing 

unit. “Especially at the transfer point between the Lokolink 

conveyors and the crusher, we caused severe damage 

when we moved the crusher ...” conceded Stefan Kuhn. The 

machine could not be as employed as flexibly as originally 

planned in the current extraction situation (opening up 

of the quarry to the approved final depth). The safety of 

the operatives and the machine were more important 

to the quarry operator. The company then invested in a 

large semi-mobile feed bin as a temporary solution and 

positioned it on an intermediate level of the quarry. With 

the LT140 below and the connected Lokolink belts, the 

primary crusher is initially set for stationary operation 

(Fig. 5). But that is to be changed in the foreseeable future: 

“Once the bottom floor has been reached in around one 

and half year’s time, the LT140 can fully unfold its full 

capabilities and feed the stationary belt via the mobile 

Lokolink belts from there,” Stefan Kuhn plans. Even today 

the two dumpers can’t supply the material fast enough to 

fully utilize the crusher capacity. The Lokotrack works in 

a single-shift operation and consumes just 35-40 l diesel 

per hour. 


64

Pic. 6: 

View of the Kuhn Quarry at the 

Pfälzer Wald Nature Reserve 

The belt weigher at the discharge conveyor measures 

the daily tonnage, which with hard granite, a full bin and a 

gap width of around 180 mm, totals around 450 t/h. Apart 

from the usual crusher tool changes, so far no significant 

repairs have been necessary. As part of the modernization 

measures, the Type 1351 Svedala machines operated 

since 1981 and 1985 are currently being replaced with 

a Metso HP300 cone crusher. The existing quarrying 

approval ensures long-term supply of the region with 

raw materials. It is therefore foreseeable that all mobile 

machines will get significantly more freedom of movement 

to permanently meet the company’s business goals.

GNSS, 3D and „smart“-drilling – 

A good team for more success in blasting! 

Drilling and Blasting plays a very important role in the production chain of an aggregates quarry. 

As the first step during the production it sets the stage for a successful production. 

Are Errors inevitable? 

Good blasting can influence positively secondary 

breaking and ease of. During the process of Drilling and 

Blasting there are a few critical steps, of which some are 

of a technical origin, while others tend to be organisational 

problems: 

Thanks to modern laserscanning (face profiling) 

technology it is possible to get a detailed view of the 

face geometry. Therefore it is also possible to take 

actions in order to optimize the blast in terms of blasted 

volume, optimum burden and hole lengths. Nevertheless 

it is mandatory for a successful blast, that the design is 

transferred to reality very precisely. The first step is to 

mark the hole positions. The more complex a blast is, the 

more potential errors can occur (see figure 1). 

Photo: 

Drilling the holes (Photo: Atlas Copco MCT GmbH) 

Normally tape measure is used to mark the hole 

positions. So it is clear the errors sum up and it is obvious 

to see that hole positions and hole separations may not 

be identical to the original blast design. Of course it also 

takes (sometimes a lot of) time to mark the hole positions 

manually. Since the quarry staff is mostly overloaded with 

work it is obvious, that lack of time also causes errors. 

As soon as all hole positions are marked, it is the drill 

rig operator’s job to drill all holes exactly the way they 

were planned. It is absolutely important that the holes are 

straight and do not deviate. However: it is also critical, 

that the holes have the correct azimuth. Drillers typically 

look for a feature, which is “far away” in order to correctly 

set up the rig’s boom and feeder, which inherently causes 

errors in the hole’s azimuth (see figure 2). 


66

Issue 01 | 2010 

Fig. 1: 

Complex blast design with 3 rows and adjusted hole 

positions for optimum burden. 

Fig. 2: 

Azimuth errors caused by setting up the rig using a 

feature, which is “far away”. 

Table. 1: 

Distances between planned and actual 

bottom hole depth based hole angle 

and hole length using the dollowing 

parameters: 

• Number of holes: 20 

• hole separation: 4m 

• 

Adistance to the remote feature: 500m 


Table 1 shows the distances between planned and actual 

bottom hole point based on hole angle and hole length. 

Additional errors caused by deviating holes are not included. 

Additional problems occur, as soon as the holes show 

different azimuths, as shown in figure 3. 

Of course it is possible to determine actual hole positions 

by doing a post drill survey. It is also common practice to 

survey the drilled holes with a hole probe and check for any 

discrepancies between the blast design and the actually drilled 

holes. However: in case there are any differences the blasting 

engineer will not be able to achieve optimum fragmentation 

of the blasted material, since hole separations and burdens 

differ from the perfect setup. 

Of course not only technical, but also organisational reasons 

are causing problems: In case a hole cannot be drilled at the 

planned position, the drill rig operator has to choose a new 

position. It is mandatory that this information finds its way to 

the blasting engineer, so that he can change his blast design 

correspondingly. It is also important, that the information has 

a quantitative measure (e.g. hole has been shifted 50cm to the 

right and 30 cm back from the face). Especially if drilling and 

blasting is carried out by different parties (contractors), this is 

even harder to achieve:

different azimuths. 

Better blast with the latest technology 

Over the past years there were both improvements in 

the survey technology (GPS/GNSS, LiDAR/laser) as well as 

in the automation of drill rigs. 

Already 6 years ago, AtlasCopco intruduced the 

SmartRIG generation of drill rigs. These SmartRIGs can 

have GNSS receivers on board as well as several other 

sensors. In order to see the benefits of the combination of 

a GNSS equipped SmartRIG with face profiling systems, 

AtlasCopco MCT Germany, EPC Germany and geo-konzept 

GmbH set up a 4 month test project. 

Issue 01 | 2010 


System description 

At the beginning the face is scanned with a 3D laser. 

After that the blasting engineer designs the blast using 

Quarry6. The blast design (hole coordinates, drill angle 

and azimuth…) is copied to a USB device and loaded to 

the drill rig. The drill rig itself carries two GNSS receivers 

and some additional sensors. Since the hole coordinates 

are in a global coordinate system (e.g. UTM) the blasting 

engineer does not have to mark the hole positions manually, 

the SmartRIG is guiding the rig operator to the planned 

positions. After selecting a hole, the rig is automatically 

setting up the boom and feeder with the correct angles, so 

that drill angle and drill azimuth fit the planned parameters 

and the rig operator can start drilling. While drilling, the 

rig is storing information like the hole start coordinates 


68

as well as the bottom hole coordinated based on the 

measured drill length, inclination and orientation of the 

boom. When the holes are drilled, the collected data can 

be imported into Quarry 6 again. The planned holes will be 

replaced by the measured holes from the rig. In this way 

the blasting engineer gets a detailed view of the drilled 

holes (hole positions, hole length, orientation…) except for 

the deviation of the holes, which still has to be measured 

by using a hole probe. 

Example: Excavation of a new bench. The hole system 

has been tested in several blasts. One of these blasts 

should be presented in more detail: A new bench should 

be created in a granite quarry. Figure 4 shows the planned 

holes in a 3D view. As a fist step 154 holes with a total 

length of 890m are planned. 

The drilling bench itself is not very flat and is inclined in 

two axes. The first and last hole of a row have a different 

orientation than the other holes in order to get a good 

inclination for the new face. It was planned to achieve a 

10% inclination for the new ramp. In combination with the 

huge number of holes and a changing drill pattern, it was 

obvious that this blast would be a good performance test 

for the system. 

Fig. 4: 

3D view of the planned blast. 

Issue 01 | 2010 


Moreover it was not a perfect place for the reception 

of GPS signals, because the place was obstructed from 

the south. As a consequence there were GPS outages in 

the morning and in the evening for about 30 minutes. The 

problem could be overcome by adding GLONASS capability 

to the receivers. 

Procedure 

A cross check of the hole coordinates from the rig and 

a post drill survey showed a correlation of better than 3cm 

(3D). 

All parties agreed that the system saved a lot of time, 

because the hole positions didn’t had to be marked 

manually. Not only the drill rig operator noticed, that it 

also saved a lot of time, that the rig set up the feeder in 

the correct way automatically corresponding to the blast 

design. Especially the first and the last hole of a row could 

be drilled quickly and very precisely. 

The only additional work for this workflow is setting up 

the GNSS base station every morning, which takes about 

5-10 minutes. Future tests will show whether the base 

station could be replaced by correction data from a GNSS 

VRS network. 


69

As all information from the rig was saved, it was also 

possible to update the blast design in the software. The 

files were sent via internet, so even the blasting engineer 

saved time because he received all necessary information 

by email without having to drive to the quarry. 

Additional benefits 

Additional benefits of the integration of GNSS are the 

documentation of the blast itself and even every single 

hole location. Therefore it is very easy to get answers 

to questions like “What’s the distance to the vibration 

monitors? What’s the distance to the nearest buildings?”. 

Issue 01 | 2010 


Of course it also makes it easy to continuously update 

mine maps. Last but not least saving data this way offers 

precise accounting for quarries. 

Result 

The blast was very successful. Blasted material showed 

good fragmentation and the ramp had exactly the planned 

inclination and is very even.

BELL EqUIPMENT LEADS THE 

“GREEN REVOLUTION” FOR OFF-HIGHWAY MACHINES 

Along with its current range of Articulated Dump Trucks (ADTs), Bell Equipment will showcase its 

solution to upcoming European Off-Highway Stage 3b emissions legislation at Bauma 2010. 

Bell will utilise SCR technology (Selective Catalytic 

Reduction) to ensure that NOx and exhaust particulate 

matter (PM) thresholds are maintained, while still ensuring 

maximum productivity and uptime for the customer. SCR 

technology will be introduced on all ADTs manufactured 

at Bell’s German assembly plant from 2011. 

Bell will continue to use Mercedes Benz 500 and 900 

series engines on its range of ADTs. Mercedes engines 

have a proven track record offering maximum power with 

a very frugal appetite for fuel. Mercedes has also been 

using SCR technology on their on-road trucks for many 

years now, and Bell is proud to pioneer this technology for 

the off-road market. 

SCR technology utilises an after treatment fluid, 

commonly called Diesel Exhaust Fluid (or DEF in America) 

or AdBlue. AdBlue consists of a non toxic Urea and water 

solution, which is stored in a separate tank. It is sprayed 

into the exhaust system and reacts with the exhaust gases 

in the catalyst. The net reaction produces inert Nitrogen 

and water vapour, both of which are common compounds 

in the atmosphere. 

To minimise the impact to the customer the 

AdBlue tank will be large enough to hold four 

shifts worth of fluid. 

SCR technology also has the following 

advantages: 

• Up to 5% better fuel consumption, means 

reduced CO2 emissions; 

• It is compatible with Bio-Diesel; 

• Increased engine power; 

• Proven engine technology ensuring reliability 

and durability; 

• Proven technology used on road transport, so 

infrastructure is already in place – over 100 

million kilometres have been done on road 

trucks with AdBlue and SCR technology; 

• Very little maintenance required; 

• No dimensional changes with Tier 3 engines, 

ensuring common global design of Bell ADTs. 

Powered by Mercedes-Benz: Bell ADTs 

meet future emission regulation with proven 

engine technology. 


72

Issue 01 | 2010 

The SCR technology is reliable and offers many inherent advantages in Off-highway practice. 

SCR vs. EGR (Comparison with EGR) 

Many other manufacturers utilise EGR technology 

for current emissions regulation. EGR (Exhaust Gas 

Recirculation) recycles exhaust gas back through the 

engine to reduce combustion temperature. This reduces 

the NOx levels; PM is reduced by a diesel particulate filter 

(DPF). 

EGR technology has the following disadvantages: 

• EGR increases heat rejection which results in a lot of 

wasted energy; 

• Catalytic converter requires energy (heat) for 

regeneration; 

• EGR engines need low ash lube oils; 

• EGR engines need low or ultra low sulfur fuel; 

• A DPF requires periodic maintenance.

European Stage 4 legislation comes into effect in Europe 

in 2014, and at that stage all off-road manufacturers will 

need to comply with legislation to reduce both exhaust 

particulate and NOx levels. Bell Equipment’s solution will 

meet the new legislation while still providing the end user 

with piece of mind, by providing maximum operational 

efficiency, reliability and durability by using proven engine 

technology.

THE EUROPEAN 

LAUNCH OF HYUNDAI’S 

9 SERIES EXCAVATOR RANGE AT BAUMA 2010 

A comprehensive range with advanced features and Hyundai’s operator-focused values! 

Hyundai’s long-anticipated 9 Series Excavators at Bauma in April 2010 will be the culmination 

of a long and detailed period of product planning, design, development and testing: 

The launch of the full range, from 1.6 to 50t, of Hyundai’s 

long-anticipated 9 Series Excavators at Bauma in April 

2010 will be the culmination of a long and detailed period 

of product planning, design, development and testing for 

what Hyundai believes will set a new standard in operator 

satisfaction. 

In addition to several pre-launch activities, including some 

prototype and pre-production previews at international 

shows and events over the past 12 months, Hyundai 

has also introduced a selective feedback programme in 

Europe, beginning in January 2010, enabling operators to 

get hands-on experience and to provide valuable feedback 

to the company. 

The focus of attention at Hyundai’s Research and 

Development department in Ulsan, Korea, over the full 

design and development proces, has been centered on the 

machine operator. Every working component and system 

has been thoroughly analysed and assessed in the light of 

its impact on both the mechanical and functional quality of 

the machine with regards to the comfort and convenience 

of the operator, as well as durability and reliability. 

The guiding principle behind this approach has been 

not just to perpetuate Hyundai’s legendary reliability, but to 

create an environment in which the operator feels happy 

and gains both pleasure and satisfaction from working 

in an operator-rewarding environment. This aspect of 

operator productivity, as well as the wide range of followon 

benefits of all-round improved efficiency and costeffectiveness, 

will appeal equally to machine owners. 

Core Product Values 

The three core operator-focused product values which 

Hyundai believes can help operators to take pleasure in 

their work are: operator preference, fast precision and 

lasting performance. And a fourth core value, intended 

specifically for the owners of 9 Series excavators, is the 

concept of the machine as a reliable and productive ‘profit 

centre’. 


74

This whole new breed of excavators enables 

operators to adjust and set machine performance 

and comfort levels to their own personal needs and 

preferences. The preference nerve centre is the 

dashboard cluster, complete with a multi-function, 

13cm (5 inch) colour LCD screen and toggle-switch. It 

provides instant access to a wide choice of functions 

and checks: a selection of power modes, work modes, 

maintenance checks, instant diagnostics and much 

more. Comfort level selection is given high priority, 

with operators now able to choose a fully adjustable 

air-suspension seat, and to set the arm-rests and 

joysticks to the preferred position and height. All -9 

Series operators will benefit from having full control 

over the cabin temperature with the standard, high 

capacity air conditioning system, and also have a builtin 

radio/MP3/CD player at their disposal, with remote 

control, to create the ideal working atmosphere. 

Fast precision is the product of efficient power 

delivery and the finesse of the hydraulic system 

controlling that power. This is an area in which Hyundai 

has come up with a unique and innovative solution: 

the ‘Posi-Nega’ hydraulic system which is installed on 

midsized 9 Series excavators. This uncomplicated, and 

therefore reliable system, combines the controllability 

benefits of a sophisticated ‘positive’ system, with 

the servicing benefits of a technically less complex 

‘negative’ system. The positive part controls boom 

and arm movements, with optimum power and speed, 

whereas the negative part feeds bucket, swing 

and travel functions when required. The variablevolume 

axial piston pump arrangement, with solenoid 

controlled valve block, provides extra sensitive control. 

In addition, the arm-in flow regeneration eliminates 

cavitation and permits smooth arm movements. Even 

the hydraulic track drives benefit from shock-proof 

stop-start functions for smoother ride and positioning. 

But for Hyundai, there is more to precision than just 

excellent hydraulic response. The operator’s view on 

the worksite has been further improved by using a 

new, narrower tube section for the cab structure, with 

low-cut and larger windows. Furthermore, the -9 Series 

cabin allows the operator to concentrate fully on the 

job at hand, in a ‘stress less’ environment, thanks to 

special low noise upholstery and low vibration cabin 

mounting. 

Issue 01 | 2010 


The dashboard cluster with LCD screen is the 

preference nerve center of the 9 Series excavator. 

The 9 Series excavator cabin, a clean, 

comfortable, ‘stress less’ work environment. 

A clear and wide view on the jobsite 

is a key element for working precisely. 

Easy access, long service intervals 

and fuel efficiency contribute to profit. 


75

The third key element in defining operator pleasure is 

the machine’s overall performance, which is dependent on 

the available power and on applying that power effectively. 

Heavy-line -9 Series excavators use the latest, well-proven 

Cummins QSB six-cylinder diesel engines, which meet 

Stage IIIA emission requirements and which, together with 

a re-designed and updated CAPO (computer aided power 

optimization) system, provide optimal power allocation. 

The best example of this is auto boom-swing priority, a 

smart function that automatically and continuously finds 

the ideal hydraulic flow balance for the boom and swing 

motions of the machine, in real time. 

Profitability is almost a natural follow-on, if the other three 

parameters are right. Hyundai machines have always been 

noted for their reliability, ensuring high earning power and 

good resale value. This reputation is further enhanced by 

applying a number of fuel efficient systems and functions, 

like one-touch and auto-deceleration and a fan clutch 

system that increases the engine cooling fan speed only 

when necessary, greatly reducing energy loss and thus 

saving fuel. Other factors which have a bearing on both 

reliability and maintenance costs include the use of high 

quality components, extended maintenance intervals with 

centralized lubrication points, long-life filters, lubrication 

and wear-parts. 

To help owners safeguard and monitor their investment, 

Hyundai is introducing its GPS technology based remote 

management system: ‘Hi-Mate’. The system facilitates 

machine tracking, tracing and monitoring anytime and 

anywhere, thus providing owners with a time saving 

advantage. With Hi-Mate it is now possible to remotely 

Issue 01 | 2010 


diagnose equipment, check operating hours as well as 

fuel level, and pinpoint the exact position of the owners’ 

Hyundai fleet. 

Vision 

Announcing this major new product initiative, Mr. J.W. 

Hwang, Managing Director of Hyundai Heavy Industries 

Europe says, “With this project for operator friendly 

equipment, we underline our company vision for building 

a better future. A vision that today has more value than 

ever before. At Hyundai, we have taken the long view, and 

invested in technology which will see our machines take 

a major step forward. We believe that the adoption of the 

four strong core principles in our design philosophy will 

show through in the products and establish a benchmark 

which others will want to emulate.” 

“To fully appreciate the value of the whole -9 Series 

package,” adds Michel de Weert, European Marketing 

Manager, “you need to see it in the flesh, and in action, 

to understand just how much operators will love these 

machines. We are expecting this range to set a new 

standard in operator appeal, and become the preferred 

choice for the discerning owner”. “It will all be on show to 

the world at Bauma – and with more besides.”

WIRTGEN PRESENTS 

BIGGEST 

In 

Issue 01 | 2010 

WORLD PREMIERE OF GIANT: 


AT BAUMA 2010 

1980, Wirtgen GmbH built the first surface miner for the mining of minerals in open-cast deposits. Today, Wirtgen 

is the market leader in this segment, offering a technically mature product portfolio for opencast mining that has 

been tried and tested in operations around the globe. The latest machine in this product division is the large 4200 SM: the 

mining giant will be presented to the industry specialists in Munich as a world premiere. With a total weight of over 200 

tonnes and a length of over 30 metres, the huge machine is the heaviest and longest exhibit of the entire Wirtgen Group 

exhibition stand. 

4200 SM: maximum performance in 

large-scale opencast mining 

At bauma, which is the leading trade fair in the industry, 

the 4200 SM will represent the successful surface mining 

division of Wirtgen GmbH that comprises three machines 

for opencast mining in different performance classes. 

Surface miners from Wirtgen offer cutting widths ranging 

from 2.20 m to 4.20 m and cutting depths of between 20 

cm and 83 cm. Wirtgen is the only manufacturer covering 

a scope of performance ranging from 100 tonnes to 3,000 

tonnes per hour. This high measure of productivity is 

attributable to the miners’ efficient cutting technology 

plus a wealth of experience gained in three decades of 

application technology. 

Productivity is clearly also the hallmark of the new 4200 

SM: the miner is a high-performance machine suitable for 

SURFACE MINER 4200 SM 

mine operators and customers in large-scale open-cast 

mining whose goal is to achieve an annual mining capacity 

in soft rock of up to 12 million tonnes while wanting to make 

full use of the benefits offered by Wirtgen’s selective mining 

technology that enables cutting, crushing and loading in a 

single working pass. 

The panorama cabin of the 4200 SM offers an excellent view for 

permanent monitoring of the work processes from the operator’s 

platform. Being isolated from the vibrations and noise emissions of the 

engine and cutting drum, the cabin offers a high degree of operator 

comfort when working in 24-hour shifts. 


78

The 4200 SM is available in two different configurations 

for operations in either hard or soft rock. For applications 

in soft rock with unconfined compressive strengths of up to 

50 MPa, the 4200 SM is equipped with a 4.20 m wide cutting 

drum unit with larger cut-ting diameter, thus permitting a 

cutting depth of up to 83 cm. The largest Wirtgen miner can 

alternatively be equipped with a drum assembly offering 

a cutting width of 4.20 m and a cutting depth of 65 cm for 

applications in hard rock with unconfined compressive 

strengths ranging from 30 MPa to 80 MPa. 

The heavy-duty machine is equipped with a 16-cylinder 

diesel engine from Cummins, making it the ideal candidate 

for a wide range of applications as its power of 1,194 kW / 

1,623 PS offers tremendous reserve capacity. Generously 

dimensioned tanks offering capacities of 2,900 l for diesel 

and 10,000 l for water additionally increase the miner’s 

uptime. 

Issue 01 | 2010 


4200 SM in the Cloudbreak Mine in Western Australia: the most 

powerful Wirtgen surface miner is operating in iron ore, achieving 

daily production rates of 12,000 tonnes per shift. 

A two-stage conveyor system with 1,800 mm wide 

primary and discharge conveyors and optional discharge 

conveyor lengths of 12,000 mm or 16,000 supports the 

surface miner’s impressive cutting performance of up to 

3,000 tonnes per hour. The conveyor’s large slewing angle 

of 180 degrees, flexible height adjustment and variable 

conveyor belt speed ensure smooth loading of large 

transport trucks even in restricted space conditions.

World firsts with extra power: 

THE NEW GENERATION- 

KLEEMANN IMPACT CRUSHERS 

At the Bauma 2010 trade fair, Kleemann 

is exhibiting two completely newly 

developed, contractor-class mobile 

impact crushers 

The foremost goal during development was to ensure 

maximum power while simultaneously providing the 

highest economy and availability. 

The secret of success: 

improving the flow of material through the entire 

machine. „To attain genuinely better performance, we were 

not satisfied with just addressing individual components. 

The key to a real increase in performance is the redesign 

of the flow of material – encompassing all components,“ 

says Thomas Kühnle, Head of Technology at Kleemann. 

Material flow concept is key to highest 

performance values 

The new material flow concept consistently prevents 

narrowing of the material stream, and the system widths 

of the conveyor elements „open“ in the material flow 

direction. This allows performance values to be attained 

that are unmatched in these size classes. For the smaller 

of the two machines, which has a crusher inlet opening of 

1100 mm, input capacities of over 350 t/h are measured. For 

the larger system, which has an inlet opening of 1300 mm, 

input capacities of 450 t/h and higher are attained.

Direct drive: 

Versatile and economical 

The outstandingly economical performance is made 

possible in part by the extremely efficient direct drive with 

which both machines are equipped. A latest-generation 

diesel engine transmits its power almost loss-free via 

a robust fluid coupling and the V-belts directly to the 

flywheel of the crusher. This drive concept also enables 

enormous versatility, as the rotor speed can be adjusted 

in four stages. For example, the machines are equally well 

suited to use in quarries and in recycling, where the input 

material is often highly inhomogenous, particularly for 

difficult processing of construction waste. 

Innovations in the individual components 

Of course, the most important new feature for the 

individual components is the heart of the machines, the 

completely newly developed impact crushers of the 

SHB series. They feature many convincing new detailed 

solutions that are unmatched: from the hydraulically 

actuated crusher inlet in extremely robust heavy-duty cast 

design to the optimised, steeper inlet angle to the new 

blow bar fastening system – these all have a positive effect 

on availability. In addition, they have an innovative fully 

hydraulic crushing gap adjustment that can be operated 

easily and in mere seconds from the operating panel. The 

crushing gap adjustment, zero gap measurement and 

overload protection functions are cleverly integrated into 

one compact unit. 

The crusher bypass was also given a complete overhaul. 

An optimised flow of material ensures that the input 

material, which is screened off by the extremely effective 

double-deck pre-screening unit and cleaned, is continually 

Issue 01 | 2010 


moved past the crusher, even at high screening output. 

One critical effect of the restriction-free material flow is 

the considerably reduced wear, particularly in the areas of 

the crusher outlet, crusher bypass and discharge chute. 

However, the crusher is not the only new feature. 

For example, there is a newly designed feeding hopper 

which, supported by a load-dependent control, enables 

continuous loading. Critical advances have also been 

made in the shape and drive of the discharge chute. Only 

its added discharge capacity makes it possible to manage 

the higher volumes of material in the critical outlet area of 

the crusher. 

Another extremely important feature for capacity and 

quality is the new classifying screening unit, which has 

been enlarged by 45% and which enables a closed circuit 

and thus the production of a defined final grain. Even for 

sieving grains up to 35 mm, the machine can make use 

of its full capacity without reducing the input volume. A 

swivelling return conveyor enables optional discharge of 

oversized particles to the waste rock pile. 

Fast changeover times, high availability 

In addition, the development process placed special 

emphasis on high availability and fast changeover times. 

Thus the hopper walls of the input unit are now not only 

lifted hydraulically, but also locked automatically by a new 

bolt system – without the need for any additional manual 

intervention. 

The bottom line: with these two machines, Kleemann 

is starting a new chapter in terms of both capacity and 

economy. 

In a class by itself in terms of capacity and availability: the new generation of mobile Kleemann impact crushers.

LIEBHERR-WHEEL LOADER L 586 2PLUS2 

NEW BLOCK HANDLING VERSION! 

wheel loader L 586 2plus2 

Liebherr’s largest wheel loader with hydrostatic 

transmission, the L 586 2plus2, was introduced at the 

2007 ‘Bauma’ and has already given excellent results in 

a variety of applications all over the world. At the 2010 

‘Bauma’ Liebherr is exhibiting a block handling equipment 

package for this model, intended specifically for the 

handling and transport of large stone blocks. This newly 

developed version of the L 586 2plus2 is for example 

ideally equipped for the loading and transport of heavy 

granite or marble blocks. 

When blocks of stone intended for further processing 

are extracted, it is preferable for them to be as large as 

possible. The maximum weight that the L 586 2plus2 can 

carry is influenced by operating conditions, but depending 

on lifting height and the stone block’s centre of gravity, it 

is possible to handle blocks weighing at least 24 metric 

tons. 

The Liebherr block handling package consists of various 

purpose-designed equipment options, including various 

stone fork patterns, shovels and a special tearout tooth. 

This extensive range of equipment enables the wheel 

loader to be closely matched to a variety of operating 

conditions and loading tasks. For maximum flexibility, the 

block handling package includes a quick-change device 

for the working attachments. 

The new block handling equipment package means 

that companies operating in this specific area can now 

benefit from the quality and the many system-related 

advantages of Liebherr’s wheel loaders with hydrostatic 

transmission. These advantages include fuel consumption 

that is as much as 25 % lower than wheel loaders with 

conventional transmission, an effectively wear-free 

service brake, minimum tyre wear and safe, convenient 

single-lever control. 

Since steep gradients are encountered in stone 

quarries, the braking effect of the hydrostatic transmission 

with its automatic self-locking action makes a major 

contribution to safety, and also avoids overheating of the 

brake system and axles.

NEW LIEBHERR - 

LB 16 LARGE ROTARY DRILLING RIG 

COMPLETES LOWER END OF RANGE 

LB 16 large rotary drilling rig 

At the 2010 ‘Bauma’ Liebherr is introducing the LB 16 large 

rotary drilling rig, an additional model that rounds off its LB 

series. This series entered production only three years ago, 

and is now available in five sizes with torque ratings between 

16 and 36 mT. 

The LB series is an ideal adjunct to the existing Liebherr 

LRB range of combined piling and drilling rigs. The LB concept 

is derived from Liebherr’s many years of experience in deep 

foundation applications, and takes into account the toughest 

demands now placed on modern rotary drilling rigs. All LB 

models are special-purpose machines for demanding drilling 

tasks. They are suitable for a wide range of applications 

including Kelly, continuous flight auger or double rotary 

drilling, and for use with soil mixing equipment. 

Exceptional performance and equipment 

features 

The new LB 16 rotary drilling rig has compact dimensions 

and is therefore also ideal for use where space is limited. Its 

minimum gateway and transport width is only 2.5 metres. It 

has a rated torque of 16 mT and is intended for a maximum 

drilling diameter of 1.5 m and drilling depths down to 34.5 m. 

For cased holes, a casing oscillator for diameters up to 1.2 m 

can be operated.

A notable technical advantage of the LB 16 is the rope 

crowd system, with a retraction force of 20 t. It offers the 

user maximum performance and reliability even under the 

toughest soil and operating conditions. 

Unique technical features of the LB 16 are its robust 

leader design and exceptionally load-resistant kinematic 

layout with generous system width. They give this large 

drilling rig significantly higher stability and strength than 

other machines of similar size. Design and construction 

of the LB 16 prepare it for the most severe demands ever 

encountered in practice. For the user, this not only means 

greater performance potential but also reduced wear, 

so that the operating life of the machine is automatically 

prolonged. 

Versatility for increased efficiency, 

low-cost transport 

The compact dimensions of this smallest member of 

the LB series of machines make it possible for the basic 

machine and the leader to be carried as a single unit. The 

overall length for transport purposes is only 15.5 metres 

and the width 2.5 m. A folding leader-base option further 

reduces transport length to only 13.5 m. This speeds up 

and simplifies machine repositioning and makes work on 

the construction site more flexible. 

The LB 16 can also be carried with the rotary in position, 

without exceeding the transport width of 2.5 m; the weight 

is then in the region of 47.5 t. 

If working height is limited, the LB 16 can be converted 

to operate with a shorter leader. Overall height is then 12.5 

m. With a 3-fold Kelly bar in use, the machine can reach 

drilling depths of as much as 16.5 m. 

Like all Liebherr piling and drilling rigs, the new LB 16 

is equipped with the well-proven Litronic control system. 

Based on the latest CANBUS generation, this control 

system comprises not only programmes for the various 

drilling methods but also servicing and troubleshooting 

information in a clearly laid-out form. A remote maintenance 

modem and a process data recorder to document the work 

carried out are available as plug-in modules.

MB S.p.A., the undisputed world leader in the production 

and sale of crusher buckets, views this new project as a 

positive turning point for India, which will progress from 

both a commercial and economic standpoint, all in full 

respect for the environment, an issue that has top priority in 

the philosophy of the Breganze-based company (currently 

in the process of obtaining the ISO 14001 certification). It is 

no accident that its buckets work using the hydraulic system 

of the excavator they are fitted up, and, unlike traditional 

crushers, offer significantly reduced transportation and 

waste disposal costs, thus allowing inert materials to be 

recycled. 

In order to build the motorway, it was decided on the 

BF120.4 bucket, which will be used to produce the stabilized 

pavements every 50 km. The peculiar feature of the BF120.4 

is that it is the only piece of equipment capable of reducing 

the size of crushed granite from 20 to 4 cm, thus making the 

job easier and more versatile. 

India will thus become familiar with the high quality of 

MB products, and will have the opportunity to see them 

in action, evaluate them and be completely satisfied

MOBILE CRUSHING AND SCREENING PLANT 


The crawler-mounted Remax 1312 MAXI crushing and 

screening plant is used for processing concrete, asphalt, 

brick, building rubble, natural stone and other recyclable 

materials. Its short set-up times, high mobility and a low 

diesel consumption of less than 30 l/h at throughputs of 

more than 250 t/h make for outstanding cost-effectiveness, 

even with small batch sizes and frequent changes of 

location. The clear diesel-electric drive layout also allows 

the plant to be directly connected to the public power grid, 

if required. 

The Remax 1312 MAXI also features discharge feeders 

which are protected against wear and tear, and equipped 

with shock absorbers, as well as a large crusher discharge 

and a rescreening unit with integrated return belt 

conveyor. The adjustable, high-performance crusher with 

regulated rotor speed ensures ideal final grain sizes during 

the entire lifespan of the wearing parts. The drive layout 

ensures excellent operational efficiency for the whole 

plant, while also reducing fuel consumption. The plant can 

be transported with a lowbed trailer or directly using the 

dolly. 

Thanks to its modular design the plant can be operated 

purely as a crushing plant (eco) or as a combined crushing 

and screening plant (maxi). Further options are available, 

such as a third crushing stage, a pivoting discharge 

conveyor, soot particle filters or a cold climate package for 

use in low-temperature locations. 


SBM’s range of mobile products covers various size and 

weight classes. The plants are generally compatible with

BODYBUILDERS HELP VOLVO FLEX 

ITS HAULER MUSCLES 

Bauma gives Volvo the chance to demonstrate a range of innovations in the articulated hauler 

sector. One of them is the Hauler Chassis programme, which provides bodybuilders with a modular 

system that forms the basis for several other superstructure versions. 

Bauma 2010 will see the international launch of the 

Hauler Chassis concept – a Volvo Construction Equipment 

programme that is designed to open up a world of 

application possibilities. While the load body is a traditional 

‘attachment’ for articulated haulers, several other effective 

hauling solutions can now be easily developed. Using 

E-Series articulated tractors, with a standard or extended 

frame as a base, bodybuilders, often in cooperation with 

Volvo dealers, can create a wide range of off-highway 

specials, such as hook lift, container hauler, concrete 

mixer, construction tractor, pipe carrier, wood chipper 

or timber transporter – satisfying customers’ needs in 

different segments. For example, a Volvo pipe carrier, 

together with a crawler excavator-based Volvo pipe layer, 

can be a perfect solution for the oil and gas industry. 

The Hauler Chassis programme gives bodybuilders 

the appropriate support throughout the design and build 

phase. Volvo has developed a dedicated web-portal, where 

drawings, diagrams and technical instructions to perform 

suitable work on a hauler chassis can be found. There is 

also clarification about legal responsibilities, warranty 

conditions and the possibility to contact Volvo experts for 

additional help if needed, so that the complete vehicle can 

perform its task safely, efficiently and economically. 


91

Total hauling solutions 

In addition to the A25E Hauler Chassis, with a hook lift, 

the Bauma 2010 exhibition in Munich will also feature three 

other Volvo articulated haulers with ‘traditional’ load bodies. 

On Volvo’s outdoor area, two medium platform haulers, the 

A25E and A30E will be joined by one large platform machine, 

the A40E FS, featuring ATC – Automatic Traction Control. 

The Full Suspension (denoted by an ‘FS’ in the machine 

designation) provides good off-road performance, allowing 

a fully loaded hauler to travel at much higher speeds, 

appearing to float over rough ground without bouncing, 

significantly increasing operator comfort, which, in turn, 

increases overall productivity. When travelling empty, 

return trips are also substantially faster due to the smooth, 

stable ride even over rough conditions, further decreasing 

the overall working cycle time. 

The Volvo FS system features automatic levelling and 

stability control. The system constantly monitors the 

Ausgabe 01 | 2010 

NEUHEITEN & REPORTAGEN 

position of the axles, with the help of sensors, adapting 

the suspension to suit the changing conditions, absorbing 

rough spots and keeping the machine level while travelling, 

loading or dumping. Vibration levels are also considerably 

lower than in conventional machines, and by providing 

a smoother ride, operators experience less fatigue, so 

efficiency increases greatly. 

Automatically efficient 

The Automatic Traction Control system fitted as an 

option to the A25E, A30E and A40E FS haulers on display 

in Munich, ensures that Volvo’s 6x4 and 6x6 capabilities 

are properly used in all, especially the most unforgiving, 

conditions. With the ATC system, the operator’s influence 

on tyre wear, fuel consumption, component life, steering 


92

ability and overall machine productivity is significantly 

reduced. Operators benefit from operating the machine 

in the safest possible way by keeping their eyes on the 

road at all times. The system chooses the optimal drive 

combination, automatically engaging or disengaging ‘dog 

clutch’ type differential locks, when needed. As a result, 

the machine keeps traction, mobility and is easier to 

operate – in all conditions. 

These are just some of the reasons why more and more 

customers, everyday, choose Volvo articulated haulers 

for applications where top class productivity, reliability, 

manoeuvrability and flexibility in the toughest conditions 

are the main decisive factors.

Hs so n t H o f e n GM bH 

AT BAUMA 2010 BHS-SONTHOFEN WILL EXHIBIT 

ITS PRODUCT RANGE IN THE FIELD OF MIXING AND 

CRUSHING TECHNOLOGY. SEVERAL INNOVATIONS IN 

BOTH FIELDS WILL BE PRESENTED TO THE MARKET 

FOR THE FIRST TIME. 

Innovations Mixing Technology 

The twin-shaft batch mixer is the main product in the field 

of mixing technology. Several thousand BHS machines are 

in operation worldwide. The production of concrete is the 

most frequent application. 

The following innovations will be presented: 

• The new series of mixer type DKXN. It has been 

especially developed for ready-mix producers using 

mostly high-slump concrete. Due to several design 

measures the prices can be calculated more attractive 

than for the other twin-shaft mixer series. 

Issue 01 | 2010 

• For mixing applications, which need higher shear forces, 

a special twin-shaft batch mixer has been developed. 

Each shaft is equipped with double mixing tools and the 

drive system allows a much higher mixing speed. This 

mixer is mainly suitable for the production of modern 

concrete recipes in the field of pre-cast concrete 

production (e.g. UHPC) or for special applications like 

landfill sealings. 

• As mixing accessory the new impulse controlled 

lubrication system will be presented. It allows an 

automatic greasing of all mixer sealings at the end of 

each production shift. The lubrication can be released 

by a control panel giving an adjustable grease quantity. 


Innovations 

Crushing Technology 

In field of the crushing technology BHS 

is specialized on vertical shaft impact 

crushers and mills. The BHS machines 

are operating to the great satisfaction of 

many aggregate producers worldwide 

in order to improve the shape of the final 

product, to produce crushed sand or for 

selective crushing applications. 

An innovation at bauma will be a semi 

mobile plant with a BHS Rotor Centrifugal 

Crusher. The plant is equipped with 

feeding hopper, conveying belts for in- 

and output and a control system. It can 

hydraulically be lifted up and down in 

order to place it on any standard lowbed 

trailer. The plant is an attractive 

solution for operators with changing 

locations. Also in export markets there 

is a growing demand for such a compact 

unit, which can easily be integrated into 

any existing facility. 

Exposed Application Examples 

Another main focus on the booth of BHS will be the 

presentation of practical applications examples. In the 

field of mixing technology several concrete columns will 

be presented, which were made from various demanding 

modern recipes (e.g. colored concrete, SCC, steel fiber 

concrete …). In the field of crushing technology several 

transparent columns will be exposed. They are filled with 

crushing examples from various kinds of rock. For a better 

analysis the individual screening fractions are placed in 

layers on top of each other. The examples demonstrate the 

wide range of applications of BHS machines in mixing and 

crushing technology.

DEHACO´S ONGOING DEVELOPMENT 

- THE NEW DE-DUST NANO 

With the DE-Dust Pico Dehaco B.V. became second at the elections for the prestigious 

“Demolition Awards”. This by the company itself developed mini nebula cannon is 

particularly suitable for smaller demolition and renovation activities indoors. Dehaco 

has not been idle in the meantime and now officially presents the DE-Dust NANO, 

Pico’s big brother. Visitors of the demolition trade fair (Sloopwerk Vakdagen) in Houten 

could already observe it. Once again Dehaco competently reacts to the demand from 

the market; the development of new products and evolving already existing products 

for the demolition and redevelopment branch for asbestos. 

Dehaco improved the DE-Dust product series of nebula cannons once again. Now the 

Pico standard has been equipped with a program switch in order to be able to adjust 

the water consumption between 4 and 8 litres per hour. To some extent the large models 

have been improved, so that this machinery can be 

A SECOND 

PLACE FOR THE 

DE-DUST PICO 

AT THE “DEMOLITION AWARDS“ 

delivered in different models easily. 

The new type of nebula cannons, which has been 

showed at the recently held demolition trade fair 

(Sloopwerk Vakdagen) in Houten, is Pico’s big 

brother and has been designed for the demolition 

of larger rooms indoors or for the demolition of 

small objects in the open air. One only has to 

connect the NANO to the water and power supply. 

This type does not need compressed air. The water consumption can be adjusted up to 80 litres per hour. The NANO can 

be easily taken along, it weighs 19 kg. An important characteristic of the atomization head is its large opening, which 

reduces the risk of clogging to zero. A force pump is also not required, which results in a reliable and simple solution. 

The first product series will be available shortly. For more information about the DE-Dust Nebula cannons please visit our 

website: www.dehaco.nl. 

Dehaco B.V. Since 1985 Dehaco sells and rents 

an extensive range of hydraulic and pneumatic 

(demolition) products, asbestos redevelopment and 

safety products. Moreover Dehaco has a modern 

test station for accessories and asbestos tools. Large 

construction and demolition companies are part of the 

clientele. Dehaco is an ambitious company, whose 

goal is it to expand its range at home and abroad.

HAZEMAG - 

DINTING LOADER EL 160 

VERSATILE TALENT! 

HAZEMAG Dinting Loader EL 160 

Dülmen, February 2010: HAZEMAG dinting loaders of 

the EL 160 series are very successful in the coal mining 

industry all over the world in the field of maintenance and 

repair of underground galleries. The compact design of 

the dinting loader EL 160 permits its application in narrow 

spaces. For crushing rock fragments five hydraulically 

driven impact chisels are integrated in the bottom of the 

box-type bucket. 

As an alternative to this bucket the machine may be fitted 

with a hydraulic rammer for especially difficult operating 

conditions as e.g. for loosening parts of rock with a high 

compressive strength or for crushing large-scale rock 

plates. 

On the BAUMA Fair in Munich HAZEMAG is going to 

present the newly-developed version of the EL 160 LS 

with a gun-mount for blast hole- and anchor bore hole 

drillings. By using modern construction- and production 

technology as well as high-quality materials this new gun 

mount achieves a low dead weight and, at the same time, a 

Issue 01 | 2010 


very high stability. This allows high drilling speeds at a high 

precision of the boring. In case of the exhibit the drilling 

tasks are carried out with a hydraulic drifter in a rotarypercussive 

drilling method up to a diameter of 52 mm and 

a boring depth of 2.4 m in hard rock. Due to the quick and 

exact positioning of the drill boom towards the starting 

point of the boring very good drilling results are achieved. A 

hydraulic quick changing device on the drill boom permits 

the conversion to a side tipping bucket for loading the 

previously blasted rock on the available conveying system 

within a short time. 

The use of modern hydraulic components coupled 

with a powerful cooling plant permits a reliable and failsafe 

operation in areas with high ambient temperatures. 

In accordance with the respective country-specific legal 

requirements the machine is equipped with electrotechnical 

components which allow the application in mines 

with methane gas.

HAZEMAG - CLAY CRUSHED 

BY A HORIZONTAL 

ROLL CRUSHER! 

Clay crushed by a Horizontal 

Roll Crusher 

Dülmen, February 2010: With the feed material 

being Clay -Sticky, Wet and Hard-with a feed 

size of 500 mm ( 19 5/8 inch) to be crushed to 

a final size of 0-60 mm ( 2 3/8” minus) was the 

challenge, These are the operational conditions 

the HAZEMAG horizontal Roll Crusher FB 0708 is 

facing a prepared to conquer. 

At the end of 2008 Peißener Tonprodukte GmbH & Co. 

KG was in the process of commissioning its new materials 

preparation plant for clay. The clay is used as an additive 

in the cement making process and has to have a specific 

size. During the crushing process, extra attention has to 

be paid to the stickiness and moisture content of the feed 

material. In addition, the feed material ( 500mm or 16 5/8” 

x 0) has to be guaranteed to be reduced to 0-60 mm (0 x 2 

3/8”) taking into consideration that the material hardness 

is 160 MPa (23,200 PSI) and impurities of limestone can 

reach 200 MPa ( 29,000 PSI). 


The customer was finally convinced of solving this 

crushing challenge because of the many advantages / 

solutions the HAZEMAG Crusher was offering. The Light 

and Compact Design combined with easy installation and 

inexpensive setup and material feeding were obvious. 

Today the HAZEMAG SOLUTION is one of the main 

plant components – assuring the company a successful 

operation. The Horizontal Roll Crusher type FB 0708 

consists of two main subassemblies: 

• Crushing Roll 

• Chain Conveyor 

The arrangement of the crushing roll above the chain 

conveyor makes the chain conveyer both the feeding 

conveyor and the discharging conveyor –All In One! Due 


97

to Single direction material flow, oversized material can be 

crushed and blockages or non crushable feed occurs (ie. 

metallic tramp metal), the blockage can be cleared by simply 

reversing the feed direction. At the same time horizontal 

crushing accommodates feeding at grade or with only 

small ramps but usually WITHOUT feeding hoppers. Even 

when hoppers are desired, as was the wish of Peißener 

Ton, feed with trucks can be easily accomplished without 

concrete pads or expensive ramps. 

The light and compact design makes it easy to transport, 

set-up and commission these crushers on site. No special 

construction work such as concrete foundations is 

necessary. Only two 8 hour shifts were needed to setup 

this plant, ready to run!

FLEXIBLE SCREENING 

HAZEMAG - VARIOWOBBLER ® 

ALWAYS THE PERFECT SETTING ! 

Always the perfect setting – 

the HAZEMAG VARIOwobbler ® 

Dülmen, February 2010: HAZEMAG & EPR GmbH in 

Dülmen introduces the HAZEMAG VARIOwobbler®, which 

represents a new generation of wobbler feeders for prescreening 

operations in crushing plants. An outstanding 

feature of this wobbler is the facility for infinitely varying the 

gap between the individual shafts by means of an effective 

hydro-mechanical control system, in order to determine 

The plant was handed over to the pleased customer after 

fulfilling a performance test of 200 metric tons per hour plus 

reaching all other parameters such as final product size 

etc. At BAUMA 2010, HAZEMAG is displaying one of the 

bigger brothers the FB 1111. This crushers’ technology can 

be used for Gypsum, Potash, Coal and many softer minerals 

at feed sizes of up to 1500 mm 5 Feet) with throughput rates 

of 1000 tph. Make it a point to stop and see Hazemag at 

BAUMA 2010 in front of Hall 2. Also, don’t forget - if you 

have to crush harder stone, our impact roll crushers can 

be used for the hard stone, also. These same machines are 

crushing granite and gneiss in the Switzerland along with 

the hard rock tunnelling application which is commonly 

know as NEAT (New Alp Transit / St. Gotthard). 

the screened product granulometry at the touch of a button 

and without the use of any tools. This system allows for 

quick and flexible reaction to changing requirements and 

ensures that the feeder is always adjusted to the correct 

setting. 

Such a system is of particular interest under the following 

circumstances: 

• When weather conditions fluctuate, there can be 

changes in the H20 content, and consequently in the 


98

Issue 01 | 2010 

screening behaviour of the material to be processed. 

The gap setting adjustment facility provides the 

optimum means to compensate for any such variations 

during the screening operation. 

• In quarry operations, the characteristics and 

properties of the recovered material – for instance, 

the proportion of actual suitable material, and thus 

the screening behaviour - can vary. In such cases, 

the optimum setting can be selected similarly at the 

touch of a button. 

• If market or customer demands and requirements 

change, i.e. should a coarser product be desired, the 

gap setting is simply widened, and likewise, if a finer 

product is called for, the gap reduced appropriately. 

In a conventional vibrating screen, to undertake such 

changes involves considerable time and effort in changing 

the actual screen grates. The new VARIOwobbler® screens 

can replace a conventional screen in a crushing plant 

without any problems; they can be designed as single- or 

multi-stage machines, according to whether or not existing 

machine height differences need to be overcome. Thanks 

to the various stages, the material flow is agitated several 

times, facilitating the downward flow of the fine material 

from the upper layers of the material bed and separating 

these fines from the coarse material. Additionally, the 

fines - which often contain a high percentage of the 

Portrait 


material‘s moisture content – are removed prior to entry 

into the crusher, avoiding the potential danger of clogging 

and caking in the actual crusher. The wobbler itself 

is not affected by sticky material. All the shafts of the 

VARIOwobbler® are individually driven. 

The use of these roller screens leads to increased 

operational safety and to a reduction in energy and 

operating costs: 

Thanks to the horizontal material flow on the roller 

screen, the downstream crusher is fed evenly and uniformly 

in a controlled manner. By separating the fines, the load on 

the crusher is reduced, resulting in less wear and reduced 

power requirements, and even possibly to the introduction 

of a reduced crusher size. 

The HAZEMAG VARIOwobbler® has been designed for the 

following applications: 

• Types of material: Limestone, Marl, Clay, Coal, Natural 

rock, Minerals with sticky inclusions, 

etc. 

• Feed size: 0 – 1.500 mm 

• Separation: 15 – 150 mm 

• Capacity: up to 2.500 t/h 


• Width: up to approx. 3,5 m

ATLAS COPCO NEW MINETRUCK MT42 – 

FOR SUPERIOR PRODUCTIVITY IN UNDERGROUND HAULAGE! 

Atlas Copco’s new Minetruck MT42 represents our next generation of underground trucks. 

This high-speed 42 tonne articulated truck has been designed to maximize productivity as 

well as provide increased safety and excellent operator comfort in underground haulage 

applications. The Minetruck MT42 is available now in Scandinavia and Canada and will be 

launched globally in 2011. 

The Minetruck MT42 

The Minetruck MT42 is powered by a fuel efficient, 

low-emission Cummins QSX15 520 hp EPA Tier 3/Stage 

IIIA engine, coupled with proven drivetrain components, 

delivering reliable performance and high speed on ramps. 

The transmission has eight forward and two reverse 

gears and features a self-diagnostic system for rapid 

troubleshooting. 

Operator comforts in the standard ISO ROPS/FOPS 

certified cabin include an air suspended forward-facing 

seat, a clear, multifunction display monitor, air conditioning 

and a trainer’s seat. The operator’s sound exposure is 

below 80 dB (A) in the cabin. Front axle suspension further 

contributes to operator comfort, while also allowing greater 

speeds on mine roadways. 

Proven performance 

An extensive, 12-month field test at Boliden’s Garpenberg 

mine in Sweden proved the capabilities of the Minetruck 

MT42, while also winning praise from the operators. “The 

Minetruck MT42 has a lot of power and with its four wheel 

drive it can go anywhere,” says Stefan Olsson, a truck 

operator for mining contractor Euromining. 

Fellow operator, Jan Lehtinen also appreciates the 

driving qualities of the new Minetruck. “The MT42 is able 

to go round corners that other trucks would need to back 

up again and again to get round. Both backwards and 

forwards, it takes corners smoothly,” he says. 

“Some trucks can lose traction on inclines, especially 

when they are not carrying a load or in wet conditions. This 

is no problem for the MT42, you just drive straight on.”

The truck’s brakes are spring applied, hydraulic released 

(SAHR) – the safest in the industry. SAHR brakes eliminate 

the need for a separate parking brake, are low maintenance 

and provide extended service life. A service bay on the side 

of the truck allows easy access to filters, valve blocks and 

service points for daily maintenance and the cabin can be 

hydraulically tilted to expose the engine bay.

CONTITECH AT BAUMA 2010: 

HIGH-TECH IN THE SERVICE OF 

ENVIRONMENTAL PROTECTION 

Conveyor belt systems help 

save energy and reduce CO2 

emissions ! 

• A new, more flexible ContiClean® A-H 

with improved low-temp resistance 

• New application areas for SICON® belt 

conveyorsystem•SCRlineskeepconstruction 

machine engines cleaner • Hydraulic 

lines more pressure-resistant all the time. 

Hanover, March 2010. ContiTech’s participation at 

bauma 2010 (hall B2, booth 303/400) focuses on technical 

innovations, eco-friendly, energy-efficient solutions and 

contributions to greater cost-efficiency. Core topics are 

energy-efficient transport solutions, a low-temperatureresistant 

conveyor belt with anti-stick properties, and 

SCR modules for exhaust gas purification in construction 

machines and heavy-duty hydraulic lines. „These 

days technical solutions alone no longer spell market 

success,“ says Hans-Jürgen Duensing, head of the 

ContiTech Conveyor Belt Group. “That’s why we keep 

an eye on providing for sustainable operation in all our 

developments. Our conveyor belt solutions can help 

to eliminate large quantities of CO2.“ Günter Frölich, 

head of ContiTech Fluid Technology also attaches great 

importance to an environmental outlook: “Our SCR hose 

lines for exhaust gas purification systems in construction 

machines contribute to cleaner air. This is why they are 

in such high demand.” 

ContiTech Conveyor Belt Group 

In Munich the ContiTech Conveyor Belt Group will be 

presenting a conveyor belt with an energy-optimized 

cover that can reduce the amount of energy a conveyor 

belt system consumes by up to 20 percent. Another 

topic of discussion is that of generating energy during 

downhill transport. It makes systems more economical 

and reduces the environmental impact. The Group is, 

moreover, also presenting a number of new products. 


104

auma is the venue for the debut of the 

latest addition to the company’s range 

of ContiClean® A-H anti-stick conveyor 

belts, which have proven themselves in 

flue-gas desulfurization systems and in 

the recycling industry. “The new type 

can also be formed into a trough so that 

it is able to transport a lot more material 

than before,” says Andreas Ullmann, 

head of the Industry segment. “A flexible 

material on the underside of the belt also 

makes it suitable for use at temperatures 

as low as minus 25°.“ 

The ContiTech Conveyor Belt Group‘s 

SICON® belt conveyor system makes 

for more cost-efficient, eco-friendly 

operations: “Thanks to its pouched shape, 

the SICON® deals with the transport of 

bulk goods in a wholly unique fashion,” 

explains Dr. Regina Gensigora, head of 

the Engineered Products segment. “This 

flexible means of transport remains 

closed from feed point to discharge point 

and is thus ideally suited to the transport 

of goods that must be contained. What’s 

more the belt exhibits enormous dexterity 

in negotiating curves.” It is thus just 

right for transporting limestone, sand 

and gypsum as well as paper, tree bark, 

woodchips and salt.

ContiTech Fluid Technology 

ContiTech Fluid Technology kbrings two new products to the 

show: 2nd generation SCR technology hose line modules that 

keep construction machine engines cleaner, and an expanded 

selection of hose line modules for hydraulic applications. “A 

technical highlight at the show is our range of complete line 

sets. They bear witness to our ability to offer customers allembracing 

solutions,” says Robert Wurm, head of the Industrial 

Lines segment. “They are delivered to the customer with fitting 

markings and filled with oil. This saves them the bother of having 

to individually screw the lines together.”

Alongside its known SCR lines – tried and tested a 

million times over – ContiTech now also offers an advanced 

2nd generation version of the lines, equipped with heated 

quick connectors that guarantee that the medium always 

thaws, right up to the plug-in connection. The connectors 

are available in two types: With PUR coating of the entire 

plug, which is suitable for high unit volumes and makes 

for a very compact solution overall, and as an extremely 

flexible modular system with hinged manifold sleeves and 

a separate heating component. The second version is 

suitable, above all, for small to medium-size unit volumes. In 

future, ContiTech will also be offering three hose types for 

the SCR line: the previous standard solution; an advanced, 

higher-quality rubber hose; and a plastic solution.

AACHEN INTERNATIONAL MINING SYMPOSIA 

AIMS 2010: 

Third International Symposium 

“Mineral Resources and Mine Development” 

26 and 27 May 2010 

Aachen, Germany 

No minerals – no future! 

Nobody denies that the world will continue to need minerals in the future. But are we 

prepared to secure tomorrows supply with critical raw materials? Which minerals will be 

needed, what will be their long-term demand and where are the deposits to accommodate 

these requirements? 

Questions that will be discussed at the third international Symposium “Mineral Resources 

and Mine Development” within the scope of the conference series “Aachen International 

Mining Symposia”. Organized by the Institute of Mining Engineering I, RWTH Aachen 

University, in cooperation with the RAG Deutsche Steinkohle and the European Association 

of Mining Industries (Euromines) it is sponsored by European Technology Platform on 

Sustainable Mineral Resources (ETP SMR), Becker Mining Systems AG, Hilti and Sandvik. 

About 50 experts from Europe, Australia, Canada, India, Japan and the United States, 

representatives of European Ministries and Geological Services as well as CEOs from 

international companies are invited to present their point of view to around 400 

participants. At a plenary session the European Technology Platform on Sustainable 

Mineral Resources (ETP SMR) will provide an interesting insight into the EU Commision´s 

Raw Materials Initiative (RMI). 

As sustainable management of mineral resources starts with the state-of-the-art extraction 

of raw materials, presentations at the Symposium also focus on practical issues such as 

the physical development of mining projects covering modern production methods as well 

as preparatory and supporting issues . 

Against the background of the imperial city of Aachen both the show at the venue and the 

themed Dinner Party will offer ample opportunity to get in contact with customers and 

colleagues.
