1 Performance
1.1 General
Hoists are designed for lifting and transporting of materials only. Under no conditions or circumstances
are hoists to be used for lifting or transporting of personnel.
Spacemaster ® SX wire rope hoists are designed for indoor use where the ambient temperature between
14°F and 104°F (-10°C and 40°C), and the elevation is less than 3300 ft [1000m], and the relative
humidity is less than 90%.
When specially equipped, the hoists may be used for outdoor use or in more extreme ambient
temperature conditions -4°F to 122°F (-20°C and 50°C) or a higher elevation.
The sound intensity level of the hoist in the assumed operating location does not exceed 70dB.
2 Hoist Duty Service Classification
2.1 FEM Hoist Duty Service Classification
Service conditions have important influence on the performance of wearing parts of a hoist such as gears,
bearings, rope, sheaves, electrical equipment, brake linings, load and lift limit devices, wheels, etc.
Careful consideration of the hoist-duty service classifications will enable the user to evaluate the
application, and to obtain a hoist designed for optimum performance and minimum maintenance.
According to FEM9.511 standard, the hoist-duty service classification can be determined from its 1) load
spectrum 2) average daily operating time.
2.1.1 FEM Load Spectrum
The load spectrum can be determined from the table below.
LIGHT
Occasional full loads.
Usually light load.
Small fixed load.
MEDIUM
Occasional full loads.
Usually light load.
Average fixed load.
HEAVY
Repetitive full loads.
Usually average load.
Heavy fixed load.
VERY HEAVY
Usually almost full loads.
Very heavy fixed load.

2.1.2 FEM Average Daily Operating Time
The average daily operating time of the hoist can be calculated from the running time of the hoisting
machinery [hours/day].
2∗
H ∗ N ∗T
t =
V ∗60
♦ H = average hoisting height [m]
♦ N = number of work cycles per hour [cycles/h]
♦ T = daily working time [h]
♦ V = hoisting speed [m/min]
2.1.3 Determining the FEM hoist duty service classification
When the load spectrum and the average daily operating time of the hoist are identified, the duty service
classification of the hoist is obtained from the table below.

4 Hoist Characteristics
The hoist characteristics table is a summary of the hoist characteristics, which include:
Height of lift and corresponding drum (length) code
Hoist speeds including alternate speeds for both two-speed and inverter controls
Availability of standard suspension types for each model
Reeving Code
Rope type code for each model
Hoist duty rating
4.1 Height of Lift and Drum Code
The height of lift along with the corresponding drum length code is listed for each basic model. In this
table, height of lift is specified in meters. To convert meters to feet, multiply by 3.281. The drum code is
included in the hoist model code.
4.2 Hoist Speeds
The published hoist speeds are nominal. The actual hoist speed could vary ±15% when comparing hoists
with the same nominal speed but with different reeving, different gearing and/or different motor type.
Always use VFD hoisting controls when better speed accuracy is needed on hoists operating together.
4.3 Suspension Type Code
Suspension types that are available for the hoist model are marked with a code. Special suspensions are
not included here.
Suspension Code in table Description
J Special low headroom hoist
L Low headroom hoist
DH Double girder trolley–high: Height above the rail is higher than the
standard trolley - to get better headroom below the rail.
D0 Double girder trolley–standard
DW Double girder trolley–low: Height above the rail is lower than the standard
trolley – to get better overhead clearance but it increases headroom.
N Normal headroom hoist
F Foot mount
4.4 Reeving Code
Reeving code Description Reeving code Description
021 2 part single 022 2 part double
041 4 part single 042 4 part double
061 6 part single 062 6 part double
081 8 part single 082 8 part double
A2 2 part single Smaller rope diameter; reduced capacity; longer lift; SX4 low headroom hoists only
A4 4 part single Smaller rope diameter; reduced capacity; longer lift; SX4 low headroom hoists only
4.5 Rope Type Code
The rope type code is listed for each height of lift. The characteristics of the wire rope can be found in the
Wire Rope section. The double-reeved hoists use two separate ropes – a right-hand lay and a left-hand
lay. See Wire Rope section for definition of Rope Type code.
4.6 Hoist Duty Rating
ASME hoist duty ratings (H3, H4, etc.) apply to hoists marked with typical U.S. capacities (for example, 1
ton = 2000 lbs = 907 kg) and do not apply to hoists marked with typical metric capacities (for example, 1
metric ton = 1,000 kg = 2,200 lbs). FEM/ISO ratings apply to hoists with typical metric capacities.

6.3 Ambient Conditions
The standard motor is designed for operation at a minimum ambient temperature –10°C to a maximum
ambient temperature 40°C and maximum altitude of 1000 meters (3280 feet).
6.4 P-Motors
The alpha character P designates a standard two-speed hoist motor and the numeric character indicates
power size.
6.5 T-Motors
The alpha character T designates a standard inverter-duty hoist motor and the numeric character that
follows indicates power size. The inverter-duty motors are specially designed for use with a variable
frequency drive.
6.6 Motor Temperature Protection
As standard, P or T type motor is equipped with normally closed, automatic reset thermal protector
embedded in the stator winding(s).
6.7 Motor Cooling
The hoist motors have ribbed outer frames to maximize convection cooling. The motors are normally
equipped with an integral cooling fan that is driven directly by the motor shaft. The shaft driven fan is only
effective when the motor is energized. In severe environmental conditions, such as high ambient
temperature, a blower fan replaces the shaft driven fan to improve the cooling.
6.8 Hoist Motor Brake
All hoist models are equipped with a disc brake to bring the load to a smooth and quick stop and to hold
the load when the motor is not energized. The disc brake is integrated into the design of the motor and
located between the motor end bell and the cooling fan. (On double reeved SX5 hoist models for drum
lengths H and J, the disc brake is mounted to the gear case cover – inline with the motor – instead of
mounted directly to the hoist motor.) A single disc with friction linings on both sides is used. The hub of
the disc is engaged on the splined motor shaft. The disc can also move axially along the shaft to
accommodate any friction lining wear.
The brake is engaged by a number of springs that force a stationary pressure plate against the friction
disc. An energized coil releases the brake. Since the brake is always engaged when the brake coil is not
energized, the brake is a fail-safe system.

7 Hoist Gearbox
c_r1ge1a
7.1 Hoist Gear Reducer
The hoist gear reducer is a multistage gear transmission with the final reduction between the motor and
the rope drum is through an external drum gear. The drum gear is attached to the inside rim of the rope
drum. A metal cover around the drum gear provides a degree of protection against contamination such as
dirt or debris. The inspection port, item 8, for the drum gear is plugged with a removable plug.
A rigid coupling couples the motor shaft to the gear shaft.

7. Inspection plug
8. Inspection port for drum gear
7.2 Hoist Gear Lubricant
The gears inside the gearbox are lubricated with semi-fluid grease (Mobilux EP 004) or oil (Mobil SHC
632) depending on the gear type. The drum gear is lubricated with grease.

If the hoist is operating for long periods in an extreme ambient condition, it is recommended that the
standard, factory-installed lubricant be replaced with an alternate lubricant type to better handle the harsh
condition. An extreme ambient condition is described as ambient temperatures less than minus
13°F/25°C or hotter than 130°F/55°C.

10.2 Heavy Duty Wire Rope – RR09
It is recommended to use IWRC heavy-duty wire rope to improve the lifetime of the rope when the hoist is
used in severe hoist applications. Examples of severe hoist applications are:
• Constant near capacity load and high duty class
• Load cycles which typically includes
Repetitive lifting especially when the load is lifted to the same position and the same part
of the rope always runs against the drum and sheaves.
Shock loading or unloading
Unordinary fleet angles due to load swing while lifting, unexpected side pulling
The IWRC heavy-duty wire rope would replace the steel core wire rope, which comes standard on the SX
hoists with 2-part or 4-part single reeving or with 2-part or 4-part double reeving.
NOTE: SX hoists with 6-part or 8-part single reeving or with 6-part or 8-part double reeving are already
furnished with heavy-duty, IWRC wire rope.
The core classification of the heavy-duty wire rope is independent wire rope core (IWRC). The inner core
strands of the IWRC are independent of the outer strands. The steel core wire rope is an eight-strand
parallel closed rope. The inner and outer strands of the steel core wire rope are closed in one operation.

11.4 DIN Hooks – HOK09
This option is used to replace the HBC type hook with the equivalent RSN size hook. The RSN hook can
be specified as an alternative to the HBC hook, which is the standard hook type in the bottom blocks of
some hoist models. Use the table in the Bottom Block Dimensions section to identify the standard hook
forging and alternative RSN hook forging on the bottom block for a particular hoist.
NOTE: Replacing the HBC hook with the RSN hook may increase headroom by 1 to 2” [25 to 50 mm].
11.5 Other Hooks – HOK07
Upon R&M’s review for compatibility and pricing, oversized DIN (RSN or HBC type) hook, or another hook
brand (Bullard, Crosby) can be specified as an alternative to the standard.
11.6 Ramshorn (twin-points) Hooks – HOK03
Upon R&M’s review for pricing, a DIN standard (15402) ramshorn hook of equal size to the RSN hook
listed for the particular bottom block can be specified as an alternative to the standard single point hook.
Each point of the ramshorn hook has a spring-loaded, flipper-type safety latch.

12 Hoist Limit Switch - Standard Setting
The hoist limit switch is a safety device that is provided to allow the setting of the hoist travel within a
prescribed travel range.
12.1 SX1 Hoist
The upper limit of hoist travel is achieved through a hook operated type limit switch and the lower limit of
hoist travel is achieved through a drum-activated limit switch.
Lower Limit Switch
The lower limit switch on the SX1 hoist is drum-activated. A trip block, which is driven by the rotating
drum, moves laterally and parallel to the drum. The trip block approaches a stationary limit switch when
the drum is lowering. The switch is fastened to a bracket. The lower limit switch setting is adjustable by
repositioning the switch on the bracket.
c_zlowli01c
Upper Limit Switch
The upper limit switch on the SX1 hoist is a hook operated limit switch, which has two switches to give
two different trip positions. The first position is for normal operation and the second position is for extra
degree of safety. If the normal operation switch has been tripped, the operator can lower the load block.
But if the extra safety switch has also been tripped, the main power is cut and the hoist cannot be
operated until the switch is manually reset to the operating position. The upper limit setting is fixed and is
not adjustable.

12.2 SX2-SX7 Hoists
The hoist limit switch on the SX2 through SX7 hoists is a rotary-type limit switch. The switch is mounted
on the hoist gearbox and the drum gear turns the switch. The limit switch is a rotary cam type and is
equipped with 4 micro-switches where each of these micro-switches has a specific function.
c_holi2a
Limit switch
View of the rotary limit switch on gearcase cover
Headroom is dimension C and lift is dimension H. Total reach is headroom + lift (C+H).
Position of micro-switch from
shaft
Micro-switch Identification Function of micro-switch
1 S1 Phase sequence supervision
2 S2 Extreme upper limit of hoist travel
3 S3 Slow-down limit
4 S4 Extreme lower limit of hoist travel
The function of the phase sequence supervision, S1 is to prevent the bottom block from two blocking
when the power phase is accidentally reversed. Two blocking is the condition under which the bottom
block or load suspended from the hook becomes jammed against the crane structure preventing further
winding up of the hoist drum.
The function of the extreme upper limit of travel, S2 is to stop the lifting when the wire rope has attained
the maximum number of windings on the drum and when the hook block is at its upper limit of travel as
determined by the rated headroom. This switch is an over-travel protection device and it is not to be used
as an automatic stop.
The function of the slow down limit, S3 is to deactivate hoist high speed and to changeover to slow speed
through this zone when nearing the upper limit of travel.
The function of the lower limit of travel, S4 is to stop the lowering when the hook is at its lower limit of
travel as determined by rated lift where no less than two wraps of rope shall remain on each anchorage of
the hoist rope drum.

13 Overload Device, Mechanical (MEC)
The hoists are equipped with an overload limit device and it is provided to protect against damage from
the attempts to lift an over-capacity load.
The standard overload limit device is electro-mechanical and it includes a prearranged stack of Belleville
washers, an adjusting screw and an electrical switch. The slight deflection of the Belleville washers in an
overload condition activates the switch, which prevents further lifting. The overload device is factory set to
cut off at 110% of the hoist rated capacity.
The mechanical overload device (MEC) is not used when the HoistMonitor is furnished with the controls.
The HoistMonitor requires an alternate overload device such as a strain gauge.

14.1 Special Low Headroom Hoist
The special low headroom hoist is suited for traveling on monorails or on overhead cranes or jib cranes
where the beam flange can be narrow or wide. In addition, the compact design of the special low
headroom hoist minimizes headroom and end approaches. The position of the drum on the special low
headroom hoist is always parallel to the girder.
The trolley flange setting for the special low headroom hoists is adjustable through the standard flange
width range, but requires adjustment to the counterweights as needed.
The ductile iron trolley wheels are crown tread type suitable for flat or tapered beam flange. The drive
wheels are pinion-driven and the gear teeth are integrally cut into the wheel flange.
Wheel bearings are permanently lubricated.
Trolleys have safety drop lugs and a provision for bumpers. Bumpers are included.

14.2 Low Headroom Hoist
The low headroom hoist is best suited for traveling on bridge cranes where the flange of the bridge girder
is generally wide. With the trolley located beside the hoist frame, it minimizes headroom and end
approaches. The position of the drum on the low headroom hoist is always parallel to the girder.
The trolley flange setting for low headroom hoists is adjustable through the standard flange width range,
but requires adjustment to the number of counterweights needed.
The ductile iron trolley wheels are crown tread type suitable for flat or tapered beam flange. The drive
wheels are pinion-driven and the gear teeth are integrally cut into the wheel flange.
Wheel bearings are permanently lubricated.
Trolleys have safety drop lugs and a provision for bumpers. Bumpers are included.
Caution!
For clearance purposes, please note the minimum depth of beam in the table below for low headroom
hoists.

14.6 Double Girder Trolley
The hoist on the top running double girder trolley is lug mounted to a suspension beam, which connects
to the end trucks. The standard position of the hoist drum is perpendicular to the bridge girders.
In the standard double girder arrangement both the trolley height (above the rail) and the headroom
(below the rail) are optimized. This arrangement is designated as the medium connection or D0 in the
model code.
Low overhead clearance (DL or DW) double girder trolley arrangements or improved headroom (DH)
double girder trolley arrangements are available as a standard option for some hoist models, which are
listed in the Hoist Characteristics table. For all other hoist models, it is a special option.
The top running double girder trolleys utilize the RT type end trucks - modified for trolley use.
Trolleys have safety drop lugs. Bumpers are included.

14.7 Trolley Gauge
The gauge of the double girder trolleys is generally defined by the frame size and drum length of a
particular hoist. The standard trolley gauge or the standard trolley gauge ranges are listed on the hoist
outline drawings. Alternate trolley gauges are available upon R&M’s review.

15 Inverter Control
Inverter drives offer built-in flexibility such as speed control types (stepless, multi-step), selection of output
speeds as well as providing over current protection, and smoother starts and stops for trolley or bridge
drives.
15.1 Infinitely Variable (EP) Speed Control
Infinitely variable (EP) speed control is stepless and gives the user control to accelerate and hold any
speed from the minimum speed to the maximum speed.
15.1.1 EP-2 Infinitely Variable
EP-2 infinitely variable allows the use of a two-step push button. The first step of the button gives run
command to minimum speed. The first step also holds the speed between minimum and maximum
speeds. The second step of the button allows acceleration up to maximum speed and holds maximum
speed.
15.1.2 EP-3 Infinitely Variable
EP-3 infinitely variable allows the use of a three-step push button. The first step of the button gives run
command to minimum speed. The second step holds any speed between minimum and maximum
speeds. The third step of the button allows acceleration up to maximum speed and holds maximum
speed. Releasing the button to the first step while running, allows deceleration down to minimum speed.
15.2 Multi-step (MS) Speed Control
Multi-step speed control (MS) gives the user two, three, or four (five on ControlMaster Select VFD)
distinct and programmable operating speeds.
15.2.1 MS-2 Multi-step
MS-2 multi-step allows the use of a two-step push button for two distinct operating speeds.
15.2.2 MS-3 Multi-step
MS-3 multi-step allows the use of a three-step push button for three distinct operating speeds.
15.2.3 MS-4 Multi-step
MS-4 multi-step allows the use of a four-step push button for four distinct operating speeds.
15.3 Dynamic Braking
Dynamic braking is where the inverter does the braking when the operator releases the control device
(i.e. pushbutton) and as the output frequency decreases to near zero, then the brake interlock relay sets
the motor brake. Braking time depends on the preset deceleration time.
15.4 Factory settings of Inverters
Unless specified otherwise, the inverters are factory set for two-step infinitely variable (EP-2) and dynamic
braking, and the output speed ratio is 4 to 1 for traveling (trolley or bridge) and 6 to 1 for hoisting.
Note: Two-step infinitely variable (EP-2) and two-step multi-speed (MS-2) allow the use of a two-step
pushbutton operator, which is the standard device in a pushbutton supplied by R&M.

19 GEK Drive
The GEK drive is equipped with a MF06 motor and a GEK gearbox. The MF06 motor is always equipped
with a brake. The GEK drive can be outfitted with either a MF06 inverter-duty motor or a two-speed motor.
The GEK gear is a multistage gear transmission. The output pinion is cut directly into the output shaft.
19.1 MF06 Inverter-duty Motor
The standard motor insulation is class F and the standard degree of protection is IP55. The motor is
outfitted with a Compact brake and with a plug to connect the electrical cable to the motor.
19.2 Compact Brake
The Compact brake is integrated into the design of a MF06 inverter-duty motor. The brake is covered.
The Compact brake is AC operated but without a separate coil to operate the brake. An electromagnetic
force produced from the energized motor stator winding releases the brake. Since the MF06 inverter-duty
motor with the Compact brake is always operated with a ControlMaster series inverter that provides
dynamic braking, the Compact brake is essentially a holding brake. The brake sets when the motor
decelerates to zero and a spring applies a clamping force.

19.3 MF06 Two-speed Motor
The standard motor insulation is class F and the standard degree of protection is IP55. The motor is
outfitted with a D.C. rectified brake and with a plug to connect the electrical cable to the motor.
19.4 D.C. Brake
The D.C. brake is engaged by a number of springs that force a stationary pressure plate against the
friction disc. An energized coil releases the brake.

20 GEK Gear Lubricants
The GEK is lubricated with Mobilux EP 004 semi-fluid grease.
If the hoist is operating in an extreme ambient condition for long periods of time, it is recommended that
the Mobilux EP 004 lubricant be replaced with a synthetic type such as Mobil SHC 007. An extreme
ambient condition is described as ambient temperatures less than minus 13°F or hotter than 130°F.

25 Hoist Monitor
The HoistMonitor is an electronic device that can be added to the hoist controls to help assure the safe
operation of the hoist and crane by monitoring selected functions of the hoist. The HoistMonitor has three
programming levels where each level has its own purpose. The three levels are HoistMonitor (basic),
HoistMonitor Select, and HoistMonitor Elite. The HoistMonitor always comes with the display unit (HS17).
25.1 Hoist Monitor – HS11
The basic functions of the HoistMonitor are:
Overload protection
Run and Fault supervision
Starting and stopping through slow speed
Sudden loading supervision
25.1.1 Overload Protection
The load sensor type and motor-torque calculation method are two types of overload protection that can
be used with the HoistMonitor. Spacemaster SX hoists ordinarily uses the load sensor type but the motortorque
calculation method can also be used on these hoists. Whenever one of these overload protection
types is used, the standard mechanical overload device (MEC) on the Spacemaster SX hoist is removed
or not used.
The overload protection device always prevents lifting when the measured load exceeds 110 percent of
the rated capacity for a brief period of time and it resets when the measured load decreases below 80
percent of the rated capacity. The overload limit of 110 percent cannot be adjusted for any one of these
overload protection types.
• Motor-Torque Calculation Method
The motor-torque calculation method can only be used with two-speed contactor controls.
It uses voltage and the motor’s current and temperature to calculate the torque, which is
then converted into load information. The current is measured with CT transformers. The
temperature is monitored with NTC thermistors, which are embedded in the motor
windings. And the voltage is measured at the power supply (L1, L2, L3). In addition to
measuring the voltage, the power supply phase is also being checked. The HoistMonitor
will continuously check for the existence of the three power supply phases. This function
makes sure that none of the phases is dropped and the supply phase order is right. The
calculation method only works when the motor is running.
• Load Sensor Type
The load sensor type can be used with inverter or contactor controls. The load sensor
device must be added separately. The sensor can be either a strain gauge (SG) or a Hall
sensor. The Spacemaster ® SX hoists uses the SG sensor. The load sensor sends an
analog signal to the HoistMonitor. The signal from the SG sensor is amplified with an
amplifier (ESD 142). The signal from the Hall sensor does not need to be amplified.
NOTE: The strain gauge overload device is calibrated at the factory only when the
HoistMonitor is furnished in the hoist electrical panel and the panel is mounted on the
hoist. Otherwise the strain gauge overload device is not calibrated at the factory and at
start-up the crane builder must calibrate the strain gauge. Calibrating requires test
weights of at least 80 percent of the rated hoist capacity.
25.1.2 Run and Fault Supervision
With the Run and Fault supervision, the HoistMonitor directly receives the lifting and lowering signals from
the controller. Before the hoist motion begins, the HoistMonitor checks for any active faults from those
functions that could be activated. If a fault exists, lifting, lowering or both, depending on the faulted
function, will be disabled until the fault is cleared. If no defaults are detected, lifting or lowering will be
allowed. One of the safety functions of the Run and Fault supervision is to monitor the hoist motor and the
brake. The brake is monitored to make sure the motor does not drive through the brake if it fails to open
and the motor is monitored to make sure the brake does not open if the motor does not start.

25.1.3 Starting and Stopping through Slow Speed
The HoistMonitor’s starting and stopping through slow speed feature is for two-speed contactor hoist
controls. (VFD control already does this function through the inverter.) The hoist motion will always start in
slow speed before allowing fast speed. This prevents “inching” and “jogging”. In addition, the HoistMonitor
will initiate slow speed for a brief moment before the hoist motor brake is closed. This helps prevent
premature brake wear that usually happens when stopping directly from fast speed.
25.1.4 Sudden Loading Supervision
Sudden loading supervision is only available with two-speed contactor controls. Sudden loading
supervision has no effect when hoisting in slow speed. It only works when lifting in fast speed. The
HositMonitor is programmed to force lifting into slow speed if it detects a sudden load condition. Sudden
load condition could occur if the bottom block or the load snags or catches on a fixed object during lifting.
25.2 Optional Features
The HoistMonitor also supports some optional features. Refer to the Hoist Options or Crane Options
sections for more information about these optional features.

25.3 Hoist Monitor Select – HS12
In addition to the basic functions of the HoistMonitor, the HoistMonitor Select level can monitor one or
more of these functions.
Safe Working Period percentage (SWP%) – tracks theoretical lifetime of the hoist
according to ISO and FEM regulations. It starts out at 100% and descends towards 0%.
Starts – tracks the number of starts of the hoist in either direction
Run time – tracks the total hoist running time in hours in both lifting and lowering
directions
Hoist cycles counter – tracks the number of hoist cycles. Tracks when it detects a load
difference of 20%
Mean load – average load handled during recorded cycles
Brake SWP% - tracks theoretical lifetime of the hoist brake. It is calculated by using the
number of starts and E-stops.
With this level you can more efficiently plan and schedule preventative maintenance and repairs. The
monitoring values can be helpful for troubleshooting. This level can also show you the usage of the hoist.
Each monitoring function is activated and set at the factory according to the specific hoist application
needed.

25.4 HoistMonitor Elite – HS13
In addition to the basic functions of the HoistMonitor, the HoistMonitor Elite level can provide one or more
of these functions, when specified to do so.
Common hoist supervision
Intermediate load limit settings (3-step)
Summing overload protection
CAN bus
The HoistMonitor Elite level is only used when two or more hoists (5 maximum) operate together or on
same bridge. Each hoist requires a HoistMonitor.
Each function is activated and set at the factory according to the specific hoist application needed.
25.4.1 Common Hoist Supervision
The purpose of this feature is to ensure the simultaneous starting and stopping of the hoisting motions. If
any one of the hoists would stop driving unexpectedly like from a tripped limit switch, then lifting or
lowering of all the hoists on the crane would stop.
25.4.2 Intermediate Load Limiting Settings
Allows up to three load steps.
25.4.3 Summing Overload Protection
This feature is mainly used to protect the crane from an overload condition where the sum of the lifted
loads of the hoists on the crane could be greater than the indicated crane capacity. If this condition would
occur, lifting would be prevented.
25.4.4 CAN bus
CAN bus links the HoistMonitors so the HoistMonitor on one hoist can access the status and load
information of another hoist or hoists.
25.5 HoistMonitor Plus – PE10
HoistMonitor Plus feature adds a display unit to the PBR style pushbutton station. This display unit is
identical to the one already furnished on the HoistMonitor. The display on controller gives the operator or
maintenance personnel floor-level access to the HoistMonitor’s information.
Depending on which HoistMonitor functions and which programming levels that were selected, the display
could show information such as:
Hoist Status information: like active fault indication, active warning indication
Tare load: displays only the weight of the load being lifted
Actual load: displays the weight of the load on the hook plus the bottom block
Access Life-time values
Set program or calibration values
Individual hoist load of multiple hoists (only when two or more hoists are used on a crane)
The accuracy of the displayed load value is approximately ±5%. It shall not be used as a calibrated
weighing scale.

29 Hoist Options
29.1 Second Hoist Brake – BRA01
A second hoist brake can be added to the SX2, SX3, SX4 or SX5 hoists for additional safety. The hoist
motor brake and the second hoist brake are connected to the same rectifier. This connection allows both
brakes to open simultaneously, but the closing of the second hoist brake is momentarily delayed to avoid
rapid stop and excessive brake wear. With this momentary delay the second brake acts as a holding
brake. The size of the second brake is similar to the hoist motor brake.
The second hoist brake has an IP55 protection rating. The IP66 hoist motor protection option also
upgrades the protection rating of the second hoist brake if it is added.
29.2 Bumper Extensions between Trolleys – DES29
The bumper extensions are generally added to each hoist as necessary when two hoists share a
common beam or girder. The extended bumpers are to ensure that the bumpers are the first point of
contact rather than any other part of the hoist.
29.3 Contactor Control, Trolley – Two-speed
Two-speed magnetic contactor control replaces the variable frequency drive. The inverter-duty motor is
replaced with a two-speed motor.
29.4 Control Transformer & Mainline Contactor – DES02
Solo hoist equipment (monorail applications) includes the control transformer and mainline contactor and
it needs to be added when the hoist is used for monorail applications. Note: the hoist on a crane uses the
control transformer and mainline contactor in the bridge panel.
29.5 Hoist Motor, IP66 Protection – HM04
Special sealed motor and brake for humid and dusty conditions. IP66 protection includes the motor and
brake assembly, unless it has the external fan option or the manual brake release option. In that case,
only the motor would be IP66 and the brake would stay IP55.
29.6 Crank Shaft for Hoist Motor – HM11
A crank handle, which slides onto the end of the motor shaft, turns the rotor of the hoist motor. The crank
handle is used to manually operate the hoist in event of a power failure, etc.
29.7 Derailment Catches for Double Girder Trolleys – OTH23
The derailment catches can be added to top running double girder trolley to prevent the trolley from
leaving the rail. The derailment catches are bolted to the end plate or rail sweep of the end truck and they
can be adjusted both in the vertical and horizontal directions so they can be adapted to various girder and
rail sizes.
29.8 Hoist Drum Brake – HS07
The hoist drum brake can be added to the SX6 and SX7 hoists for additional safety - it is in addition to the
standard motor brake. There is a reduction in the standard height of lift when the hoist drum brake is
added to the hoist because some of the rope scoring on the drum end opposite of the gear case is
removed so the brake can be mounted there. Use the QuoteMaster TM program to determine the reduction
of height of lift and which SX6 and SX7 hoist models can be outfitted with the hoist drum brake.
The drum brake consists of two separate brakes to do different functions. One is as a holding brake and
the other is as an over-speed brake. The hoist can be outfitted with either the holding brake or the overspeed
brake. Or the hoist can be outfitted with both drum brakes for holding and for over-speed. A
solenoid operates the holding brake, which sets and then holds the load when lifting or lowering has
stopped. The over-speed brake is strictly mechanical and has a mechanism that will set the brake if the
drum rotation is over-speeding by 25%. The over-speed brake will bring the load to a smooth stop if it
happens to activate.

29.9 Hoist Motor External Fan – MOT08
The external fan improves the cooling of the hoist motor. The fan starts automatically when the hoist
motor is energized and a timer relay allows the fan to run 30 minutes after the motor is de-energized. The
external fan offers many advantages:
Maximum ambient temperature increases from 40 o C to 60 o C.
Ratio of slow to fast speed can be higher than 3:1.
NOTE: Motor with external fan increases the overall length of the motor by 4” [100mm].
29.9.1 Slack Rope Protection (10% of nominal load) – HS16
The slack rope protection prevents the further lowering of the bottom block when a slack rope condition is
detected under preset limits. The slack rope protection can only be used when a below-the-hook device is
attached to the load hook. This is because the slack rope protection requires a dead weight of 10%
minimum of the nominal capacity to make it work. It also requires the HoistMonitor.
A bypass switch to override the slack rope protection is highly recommended. The bypass switch can be
mounted on the pendant or the bridge panel. The bypass switch on the pendant would allow the operator
to override the slack rope protection for operational purposes. The bypass switch on the control enclosure
would allow only maintenance personnel to override the slack rope protection.
29.9.2 Load Limiter, Two-step – LIM07
This feature can include one intermediate load limit output and one overload limit output. It requires the
HoistMonitor.
29.9.3 Load Limiter, Three-step – LIM08
This feature can include two intermediate load limit outputs and one overload limit output. It requires the
HoistMonitor.
29.9.4 Overload Indication, Light and Horn Combination – LOA05
Both a red light and a horn are activated together to alert the operator if a capacity overload condition
occurs. The warning devices are mounted to the bridge panel. For monorail applications, the warning
devices are mounted to underside of the hoist. This feature can be used with the standard mechanical
overload device (MEC) or with the HoistMonitor’s overload protection.
29.9.5 Overload Indication, Red Light – LOA07
A red light is activated to alert the operator if a capacity overload condition occurs. The warning device is
mounted to the bridge control enclosure when the hoist controls are setup for a crane application.
Otherwise the warning device is mounted to underside of the hoist if the hoist controls are setup for a
monorail application. This feature can be used with the standard mechanical overload device (MEC) or
with the HoistMonitor’s overload protection.
29.10 Hoist without Electrical Controls – ELE65
This option omits the two-speed contactor hoist controls. Typically this option is used for foot-mounted
hoists where the user consolidates controls for hoist and trolley motions under one control enclosure.
When omitting controls, the hoist panel includes always a wired hoist brake rectifier and terminals for
leads of accessory items. Hoist motor and limit switches leads are also connected to terminals.
NOTE: This option does not apply to omitting the hoist inverter controls. It is highly recommended to use
R&M’s ControlMaster variable frequency drives with R&M’s hoisting and traveling motors.

29.11 Limit Switch, Hoist Operating with Bypass – LIM17
The function of the bypass button is to override switch 3 on the rotary limit switch so the operation of
switch 2 can be tested. When the bypass button is furnished, the function of switch S3 is set up differently
from the standard setting. For more information about the standard setting, go to Hoist Limit Switch –
Standard Setting. Switch S3 becomes an operating limit switch rather than a slow-down limit and when
tripped it stops the hoist motion in the UP direction. The bypass button is mounted on the controller.
Through this bypass zone, the hook block moves in slow speed only.
Position of micro-switch from shaft Micro-switch Identification Function of micro-switch
1 S1 Phase sequence supervision
2 S2 Upper limit of hoist travel
3 S3 Upper operating limit
4 S4 Lower limit of hoist travel
The function of the phase sequence supervision, S1 is to prevent the bottom block from two blocking
when the power phase is accidentally reversed. Two blocking is the condition under which the bottom
block or load suspended from the hook becomes jammed against the crane structure preventing further
winding up of the hoist drum.
The function of the extreme upper limit of travel, S2 is to stop the lifting when the wire rope has attained
the maximum number of windings on the drum and when the hook block is at its upper limit of travel as
determined by the rated headroom. This switch is an over-travel protection device and it is not to be used
as an automatic stop.
The function of the lower limit of travel, S4 is to stop the lowering when the hook is at its lower limit of
travel as determined by rated lift where no less than two wraps of rope shall remain on each anchorage of
the hoist rope drum.

29.12 Limit Switch, Extra - Level Setting – LIM16
The extra-level setting is available is done by modifying the standard setting of the four-element rotary
limit switch. (Phase mismatch supervision is not available in this arrangement.) For more information
about the standard setting, go to Hoist Limit Switch – Standard Setting.
Headroom is dimension C and lift is dimension H. Total reach is headroom + lift.
Position of micro-switch from shaft Micro-switch Identification Function of micro-switch
1 S1 Upper limit of hoist travel
2 S2 Upper slow-down limit
3 S3 Extra level limit of hoist travel
4 S4 Lower limit of hoist travel
The function of the upper limit of travel, S1 is to stop the lifting when the wire rope has attained the
maximum number of windings on the drum and when the hook block is at its upper limit of travel as
determined by the rated headroom. This switch is an over-travel protection device and it is not to be used
as an automatic stop.
The function of the upper slow down limit, S2 is to deactivate hoist high speed and to changeover to slow
speed through this zone when nearing the upper limit of travel.
The extra level limit of travel, S3 is to give the user an extra limit to set and wire according to user’s
application. Although this switch is not wired in the hoist circuit, it is wired to terminals for easy access.
The function of the lower limit of travel, S4 is to stop the lowering when the hook is at its lower limit of
travel as determined by rated lift where no less than two wraps of rope shall remain on each anchorage of
the hoist rope drum.

29.13 Limit Switch, Hook Operated – HS22
The hook operated limit switch is a safety device. The hook block moving in the up direction trips the limit
switch when the block is close to the upper limit of travel. There are two different kinds of hook operated
limit switches.
Automatic Reset
With the automatic reset, only the UP circuit cuts out if the limit switch is tripped. The limit switch resets
when the operator gives the DOWN command to lower the hook block off the trip lever.
Manual Reset
With the manual reset, both the UP and DOWN hoist circuits are cut off if the limit switch is tripped. To
resume normal operation of the hoist, maintenance personnel must manually reset the limit switch.
NOTE: Headroom increases about 5” [125mm] from standard when hoist is equipped with a hook block
operated limit switch.
29.14 Limit Switch, Trolley Traveling One-step (Slowdown) – LIM13
This features changes fast trolley speed to slow trolley speed when activated. Ramp functions are applied
if trolley controls are inverter with dynamic braking activated.
NOTE: The one-step (slowdown) trolley traveling limit switch cannot be used with the CMXC007 inverter
and stepless (EP) speed control. The CMXC007 inverter can be used with the one-step (slowdown) limit
switch when the speed control is multi-step (MS).
29.15 Limit Switch, Trolley Traveling One-step (Stop) – LIM14
This features stops trolley traveling when activated. Ramp functions are applied if trolley control is inverter
with dynamic braking.
29.16 Limit Switch, Trolley Traveling Two-step (Slowdown + Stop) - LIM15
This features changes fast trolley speed to slow trolley speed when activated. Second step of limit switch
stops the trolley traveling when activated. Ramp functions are applied if trolley control is inverter with
dynamic braking.
29.17 Lockable Hook in Bottom Block – HOK02

For the standard flange width range on the normal headroom hoist, go to the Trolley section.
29.41 Multi-hook Leveling – HS18
The leveling function is a feature designed for multi-hook hoist applications and is most useful when the
hoists are handling fixed or similar loads such as containers or long objects.
In normal operations, lifting or lowering for all the hoists will stop when the HoistMonitior unit in any one of
the hoists detects a fault or a tripped hoist limit switch. This prevents the load from tilting.
The leveling of the hooks is typically done with the upper limit switch but it can be set up to be done with
the lower limit switch. The leveling function allows each hoist to continue hoisting close to the upper limit
switch until the hooks are leveled.
30 Hoist Speeds
See the Hoist Characteristics section for alternate hoist speeds.
NOTE: The published hoist speeds are nominal. The actual hoist speed could vary ±15% when
comparing hoists with the same nominal speed but with different reeving, different gearing and/or different
motor type. Always use VFD hoisting controls when better speed accuracy is needed on hoists operating
together.

36.3 Plug Kits and Stainless Steel Enclosures
Plug kits are not available for stainless steel enclosures with an IP-66 rating. In lieu of plugs, cables are
hardwired-connected and cable glands are used to seal the cable connection to the enclosure.
Plug kits are available for stainless steel enclosures with an IP-55 rating. The same plug kit rules for the
standard enclosures apply to the stainless steel enclosures with the IP-55 rating.
37 Bridge Girder
The type of bridge girders that is suggested from the QuoteMaster TM program is either profile or box
girder. Profile girders are commercial beams like Wide Flange. Box girders are the built-up beams from
plates. The suggested bridge girder is engineered to meet both the span and capacity specified for the
crane application, where the maximum allowable deflection does not exceed 1/888 of the span.
NOTE: The adequacy of the bridge girder and the joint connection for the crane application is the
responsibility of the crane builder and should be verified or determined by qualified personnel.
The under-hung trolley is adjusted for the flange of the suggested bridge beam or a predetermined flange
width.
It is the responsibility of the crane builder to furnish the bridge girder.
38 Tandem Hoists
Tandem hoists are defined as two identical hoist models, which have similar speeds, reeving, gear and
motor types, and equal capacity, operating in tandem or individually.
The crane package for tandem hoists includes:
Bumper extensions on each hoist as necessary
Additional festoon and festoon hardware for the second hoist
Common pushbutton pendant (on sliding festoon rail) with either a two-position or threeposition
selector switch
Tandem controls in the bridge panel
The use of a three-position selector switch will allow the operator to operate hoist 1 or hoist 2
independently or together in tandem. The two-position selector switch will allow the operator to operate
hoist 1 or hoist 2 independently, but not together in tandem.
Adding the HoistMonitor Elite to the controls of the tandem hoists should also be considered. Learn more
about the HoistMonitor Elite features and the options it supports in the Hoist Monitor section.
NOTE: The published hoist speeds are nominal. The actual hoist speed could vary ±15% when
comparing hoists with the same nominal speed but with different reeving, different gearing and/or different
motor type. Always use VFD hoisting controls when better speed accuracy is needed on hoists operating
together.

39 Crane Options
39.1 Anti-collision Device for Crane – OTH08
The anti-collision device prevents cranes on the same runway from approaching each other at a high rate
of speed.
The anti-collision device consists of a sensor and reflector. The sensor is wired to the bridge controls. The
reflector is placed on the opposite crane directly across from the sensor. The maximum sensing distance
is 20 feet [6m]. The maximum traveling speed is 105 fpm [32 m/min].
When selecting the anti-collision device for a crane kit, it is not essential to specify the actual location of
the device on the crane. But it is important to specify whether the crane gets the device on one side or
both sides. When there are two cranes on the runway, a sensor and a reflector is needed on one side of
each crane. When there are three or more cranes on the runway, a sensor and a reflector is needed on
both sides of the middle crane(s), and a sensor and a reflector is needed on one side of the end cranes.
There are three operation modes to choose from when specifying the anti-collision device. The modes
are slow down, slow down + stop, or stop. In the slow down mode, once crane is within the sensing
distance, the bridge can only be driven in slow speed. In the slow down + stop mode, once the crane is
within the sensing distance, the bridge drive is forced to slow speed and then the crane is stopped. In the
stop mode, once crane is within the sensing distance, the crane is stopped regardless how fast the crane
is traveling.
There are two types of sensor to choose from when specifying the anti-collision device. The types are
photo detector and ultrasonic. The photo detector sensor is not recommended for outdoor use or
dusty environments because the sunlight or dust decreases the sensing distance. Choose the
ultrasonic sensor when the crane is for outdoor use or used in dusty environments.
39.2 Anti-collision Device for Second Crane – BT20
Anti-collision device for second crane is for an existing crane already on the runway of the new crane.
The sensor type for the existing crane must match the one selected for the new crane. The bridge speed
of the existing crane must be specified on the order. The sensing distance decreases when the traveling
speed is over 125 fpm [38 m/min].
39.3 Bumper Extensions between End Trucks – DES44
The bumper extensions are generally added to one end of each end truck as necessary when two cranes
share a common runway. The extended bumpers are to ensure that the bumpers are the first point of
contact. Height of the extension matches existing bumper line of the end trucks. Extension length must be
specified, maximum 40 inches [1 m].
39.4 Contactor Control, Bridge –Two-speed
Two-speed contactor control replaces the variable frequency drive, which is standard equipment. The
contactor is the IEC type.
39.5 Flashing Light for Bridge Traveling – ELE20
The flashing light beacon is used to warn people that the crane is moving. The unit is delivered loose.
39.6 Horn – ELE05
The operator activates the horn from a button (second step of the start button or a separate button) on the
controller. Sound output level of the horn is 94dB minimum at 10 feet [3 m]. The horn is CSA and UL
approved.

39.7 Limit Switch, Bridge Traveling One-step (Stop) – LIM11
This features stops the bridge traveling when activated. Ramp functions are applied if the bridge
controller is an inverter programmed with dynamic braking.
39.8 Limit Switch, Bridge Traveling Two-step (Slowdown + Stop) – LIM12
This features changes fast bridge speed to slow speed when activated. Second step of limit switch stops
the bridge traveling when activated. Ramp functions are applied if the bridge controller is an inverter
programmed with dynamic braking.
39.9 Limit Switch, Hook Operated, Trips Mainline Contactor – ELE64
The block-operated limit switch is wired in the bridge mainline contactor circuit. When the hook operated
limit switch is tripped the mainline contactor is opened and shuts off power to the crane. To restore power
to the crane, press the START button on the pendant.
Note: Hoist headroom increases 5” to 6” [125 mm to 150 mm] from standard when the hoist is equipped
with the block-operated limit.
39.10 Limit Switch, Trolley Travel, Trips all Trolleys on Bridge – ELE63
When the traveling limit switch on any one of the trolleys on the same bridge is activated, the trolleys
either slow down or stop depending on the setting. This feature is necessary in common drive
applications.
39.11 Load Display – HS09
The load display is mounted on the bridge near the bridge panel. The accuracy of the displayed load
value is approximately ±5%. It shall not be used as a calibrated weighing scale. The height of the LED
characters on the display is about 100 mm. The load display requires the HoistMonitor.
39.12 Load Display for Two Hoists on Crane – HS10
The load display is mounted on the bridge near the bridge panel. The accuracy of the displayed load
value is approximately ±5%. It shall not be used as a calibrated weighing scale. The height of the LED
characters on the display is about 100 mm. The load display requires the HoistMonitor + HoistMonitor
Elite.
39.13 Longer Chain for Trolley Tow Arm & Festoon
Standard length of the festoon towing chain is nearly six feet [1.8m]. A longer festoon towing arm chain of
nearly 12 feet [3.8m] is perhaps necessary on longer span cranes when the length of a stacked festoon
cable is deeper. In these cases, a longer festoon towing chain allows the hoist to maintain a standard
hoist end approach on the festoon storage end of the crane.
39.14 Manual Brake Release for Bridge Motor – BRA06
A spring-loaded manual hand release is used to open the disc plates of the brake. The hand release can
be outfitted to the D.C. brakes but not the Compact brake, which is used on most of the MF06 inverterduty
motors.
39.15 Nonstandard Voltage/frequency for Crane
Standard voltages: 208v/230v/460v/575v – 3ph – 60Hz. Other voltages are available on request.
39.16 Pliotex Type Wire Marking – ELE48
Pliotex type wire marking is a plastic marker with one character in it. These markers are permanent and
thy can be used where high humidity is present.

39.24 Thermal Protection for Bridge Motor – MOT16
The thermal overload relay is protecting each phase.
39.25 Transformer for Entire Crane – ELE67
The autotransformer for the entire crane is to supply proper power to the inverters when there is a hoist
inverter and the power supply is something other than 460 volts - 60 Hertz (or 415 volts - 50 Hertz).
39.26 Transformer for Bridge Control – ELE69
This transformer is located in the control panel and it is to supply proper power to the bridge control
inverter.
39.27 Bridge Motor, IP66 Protection – BM04
Special sealed motor and brake for humid and dusty conditions. IP66 protection includes the motor and
brake assembly, unless it has the external fan option or the manual brake release option. In that case,
only the motor would be IP66 and the brake would stay IP55.
