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 can be
between 14°F [-10°C] and 104°F [40°C], 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, in more extreme ambient conditions,
or at a higher elevation. See the Outdoors Service & Other Environments section for the categories
and the special protection features.
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, and 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.

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 code is listed for each basic model.
4.2 Hoist Speed Accuracy
The actual hoist speed of hoist units with the same nominal speed but with a different reeving system,
gearing ratio, and motor types could vary ±15%. Better speed accuracy can be attained through VFD
(inverter) controls where the speeds of both hoists can be fine-tuned through the inverter parameters.
Exact matching speeds could be important for hoists that would operate 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
ControlMaster inverters. T-motors do not have over-speed capability.
6.6 A-Motors
The alpha character A designates an inverter-duty hoist motor and the numeric character that follows
indicates power size. The A-motor is specially designed to use with ControlMaster inverters and has
adjustable speed range (ASR) capability.
6.7 S-Motors
The alpha character S designates an inverter-duty hoist motor and the numeric character that follows
indicates power size. The S-motor is specially designed to use with ControlMaster inverters and has
extended speed range (ESR) capability.
6.8 Motor Temperature Protection
As standard, all hoist motors are equipped with normally closed, automatic reset thermal protector
embedded in the stator winding(s).
6.9 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. Motors that are used in severe environmental conditions, such as
high ambient temperature, a blower fan will replace the shaft driven fan to improve the cooling.
6.10 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 – in line 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.

7.1 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 a 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.
The gear class for the hoist gears meets AGMA 12.
7.2 Hoist Gear Lubricant
The standard lubricant for the gears inside the hoist gearbox is semi-fluid grease (Mobilux EP 004) or oil
(Mobil SHC 632) depending on the gear type. The standard lubricant for the drum gear is grease
(Almagard 3752).

10.2 Heavy Duty Wire Rope – RR09
It is recommended to use heavy-duty IWRC wire rope to improve the lifetime of the rope when the hoist is
used in severe hoist applications. Examples of a severe hoist application are:
• Constant near capacity loading and high duty cycle
• 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
NOTE: The heavy-duty IWRC wire rope is standard on SX hoists with 6-part or 8-part single reeving or
with 6-part or 8-part double reeving. It is not standard on SX hoists with 2-part or 4-part single reeving or
with 2-part or 4-part double reeving.
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.

11.5 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 equivalent RSN hook may increase headroom by 1 to 2” [25 to
50 mm].

12 Hoist Limit Switch - Standard
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 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.
Limit switch
c_holi2a
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).
Operation of the Standard Rotary Limit Switch
Position of micro-switch from Micro-switch Identification Function of micro-switch
shaft
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) cannot be used together with the HoistMonitor ® . The
HoistMonitor ® requires an overload device such as a strain gauge.

14.1 Low Headroom Hoist
The low headroom hoist minimizes headroom as well as end approaches, and with its exceptional flange
adjustment range, the low headroom hoist is best suited to run on bridge cranes where the flange of the
bridge girder is generally wide. The position of the drum on the low headroom hoist is always parallel to
the girder.
The trolley can be adjusted to any width within the standard adjustment range, but it may require
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.

14.5 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.
The standard connection (D0) for double girder trolleys is a medium connection that optimizes both the
trolley height above the rail and the headroom (rail-to-hook).
The low connection construction (DL) and the high connection construction (DH) for double girder trolleys
are available for some hoist models as a standard option. Refer to in the Hoist Characteristics table for
those models. The low connection construction minimizes the height of the trolley above the rail for better
overhead clearance, but headroom increases (rail-to-hook). The high connection construction minimizes
the rail to hook distance for better headroom but it increases the height of the trolley above the rail.
The top running double girder trolleys utilize the design of the RT or RTN end trucks - modified for trolley
use.
Trolleys have safety drop lugs. Bumpers are included.

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.
15.1 Speed Control Types
Infinitely variable (EP) is the more commonly used speed control for hoists and cranes. Infinitely variable
speed control is stepless. It gives the user flexibility to control, accelerate and hold any speed from the
minimum speed up to the maximum speed.
Multi-step speed control (MS) gives the user two, three, four, or five distinct and programmable operating
speeds depending on the inverter capabilities.
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.
15.1.3 MS-2 Multi-step
MS-2 multi-step allows the use of a two-step push button for two distinct operating speeds.
15.1.4 MS-3 Multi-step
MS-3 multi-step allows the use of a three-step push button for three distinct operating speeds.
15.1.5 MS-4 Multi-step
MS-4 multi-step allows the use of a four-step push button for four distinct operating speeds.
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 in controllers supplied by R&M.
15.2 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.
15.3 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.

25% and 40%, the extended speed steadily declines as the load increases. At 40%, the hoisting speed
cannot extend past the rated hoist speed and the rated hoist speed remains constant as load the increase
towards full load. The inverter will automatically make the adjustment based on the load.

ASR ratio (maximum) 15:1
With ASR the hoist speed will vary depending on the load. ASR also includes an extended speed range.
The extended speed range starts when the load is less than 40% the rated capacity. The extended speed
reaches maximum when the load is less than 10% of the rated capacity. Between 10% and 40% of the
rated capacity, the extended speed steadily declines as the load increases. Beginning at 40% of the rated
capacity, the hoist speed cannot extend past the rated speed and then, as the load increases towards full
load, the hoist speed continuously decreases. And because of that the rated hoist speed at full load is half
of that when compared to a two-speed P-motor or other ControlMaster inverter options. The inverter will
automatically make the adjustment based on the load.

19 GEK Drive
The GEK drive is equipped with a MF06 motor and a GEK gearbox. The motor is always equipped with a
brake. The GEK drive can be outfitted with either an inverter-duty motor or a two-speed motor. The GEK
gearbox is a multistage gear transmission and the gear class meets AGMA 10. The output pinion is cut
directly into the output shaft.
19.1 MF06 Inverter-duty Motor
The standard motor insulation is class F. The standard degree of protection of the motor and brake is
IP55. The motor is outfitted with a Compact brake, and it is outfitted with a plug to connect the electrical
cable to the motor.
19.2 MF06 Two-speed Motor
The standard motor insulation is class F. The standard degree of protection of the motor and brake is
IP55. The motor is outfitted with a D.C. rectified brake, and it is outfitted with a plug to connect the
electrical cable to the motor.
20 GEK Gear Lubricants
The standard lubricant for gears in the GEK gearbox is Mobilux EP 004 semi-fluid grease.
If the crane/hoist is specified that it will be operated in ambient temperatures below 14°F [-10°C] or in
ambient temperatures above 104°F [40°C] for long periods of time, the standard lubricant will be replaced
with a synthetic lubricant.

21.3 Compact Brake
The Compact brake, which is only used on the MF06 inverter-duty motors, is AC operated, but without a
separate coil to operate the brake. The brake is released from an electromagnetic force produced from
the energized motor stator winding. Since the motor with the Compact brake is always operated with a
ControlMaster TM series inverter that provides dynamic braking, the Compact brake essentially functions
as a holding brake. The brake sets when the motor decelerates to zero and a spring applies a clamping
force.

21.4 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.

25 HoistMonitor ®
HoistMonitor ® is an electronic device that can be added to the controls to help assure the safe operation
of the hoist and crane by monitoring selected functions of the hoist. The HoistMonitor ® has two additional
programming levels where each level has its own purpose. The names of those levels are HoistMonitor ®
Select, and HoistMonitor ® Elite. The HoistMonitor ® always comes with the display unit (HS17).
25.1 HoistMonitor ® – 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 – HS03
The load sensor type and motor-torque calculation method are two types of overload protection that can
be used with the HoistMonitor ® . Ordinarily the Spacemaster ® SX hoists uses the load sensor type with the
HoistMonitor ® . The mechanical overload device (MEC) on the Spacemaster ® SX hoist cannot be used
with the HoistMonitor ® .
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 with the motor–torque
calculation method or the load sensor type.
• Motor-Torque Calculation Method (POW)
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 (Strain Gauge)
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.
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.
25.1.2 Starting and Stopping through Slow Speed
The 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.

www.rmhoist.com
25.1.3 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.
Slack rope supervision – HS16
2-step load limiter – LIM07 (overload protection)
3-step load limiter – LIM08 (overload protection)
Load display – HS09
Load display for total or individual load – HS28
Overload indication light and horn – LOA05
Overload indication light – LOA07
25.3 Calibration
The HoistMonitor ® when coupled with the strain gauge (SG) overload device will be completely calibrated
by R&M at the Springfield factory given that the calibration requires measured test weights of at least
80% of the rated capacity of the hoist(s). Exclusions apply.
It is important to note that in some cases, fine-tuning of the HoistMonitor ® may be needed at the
commissioning of the crane/ /hoist and must be performed by others. Fine-tuning does not usually require
test weights, but may need a known, measured load.
25.4 HoistMonitor ® Select – HS12
In addition to the basic functions, 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.

25.5 HoistMonitor ® Elite – HS13
The HoistMonitor ® Elite is used when multiple hoists (2-5 hoists) operate together or individually on the
same crane. Each hoist requires a HoistMonitor ® when multiple hoists are involved.
The HoistMonitor ® Elite can provide one or more of these functions, when specified to do so.
Common hoist supervision
Intermediate load limit settings
Summing overload protection
CAN bus
The HoistMonitor ® Elite functions are only activated at the factory according to the specific hoist
application needed.
25.5.1 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.
25.5.2 Intermediate Load Limiting Settings
The feature allows for up to three load steps.
25.5.3 Summing Overload Protection
This feature is 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.
25.5.4 CAN bus
CAN bus links the HoistMonitor ® of each hoist to one another. This means the HoistMonitor ® on one hoist
can access the status and load information of another hoist or hoists.

26 Outdoors Service & Other Environments
This section covers the recommended protection features needed for hoists or cranes that are located
outdoors and/or operate in other special environments.
The hoist and crane components are designed/selected to operate indoors where the ambient
temperature is 14 o F [-10 o C] minimum and 104 o F [+40 o C] maximum, and the relative humidity below 90%,
and the elevation is not greater than 3300 ft [1000m] above sea level.
If specially equipped, the hoist or crane can operate in special environments.
26.1 Environment Categories
1. Outdoors, (under roof) - the crane or hoist is operated outdoors and it is located or stored under
a permanent roof or similar structure, which provides a degree of protection against the elements.
See the Protection Feature Summary for the factory recommended protection features for this
category. Ambient temperature range is +14 o F [-10 o C] - 104 o F [40 o C].
2. Outdoors, no roof - the hoist or crane will operate outdoors in the open. See the Protection
Feature Summary for the factory recommended protection features for this category. Ambient
temperature range is +14 o F [-10 o C] - 104 o F [40 o C].
3. High humidity - the hoist or crane will operate in a location (indoors or outdoors) where the
relative humidity is consistently above 90%. See the Protection Feature Summary for the factory
recommended protection features for this category.
4. High temperature - the hoist or crane will operate in a location (indoors or outdoors) where the
ambient temperature can be consistently above 104 o F [40 o C] but not greater than 131 o F [55 o C].
See the Protection Feature Summary for the factory recommended protection features for this
category. In addition, the motors are sized according to the motor rules for high temperatures,
which could mean a higher capacity hoist is needed. The table below shows the maximum hoist
capacity to make up for the power reduction of the hoist and trolley motors.
Ambient Temperature
Maximum capacity of hoist
104 o F [40 o C] 100%
113 o F [45 o C] 95%
122 o F [50 o C] 90%
131 o F [55 o C] 85%
5. Low temperature - the hoist or crane will operate in a location (indoors or outdoors) where
ambient temperature can be consistently below +14 o F [-10 o C] but not lower than -4 o F [-20 o C].
(For temperatures below -4 o F [-20 o C], contact R&M for assistance.) See the Protection Feature
Summary for the factory recommended protection features for this category.
6. Wind – wind loads are taken in consideration for the selection of the crane structural components
and the traveling drives only when the crane is specified for outdoors. Wind loads are not
considered for the component selection for indoor cranes.
7. Dust - the hoist or crane is in an area where a high level of (non-explosive) dust (concrete dust,
sand dust, etc) is present. See the Protection Feature Summary for the factory recommended
protection features for this category.
8. High Altitude - The capacity of the hoist is reduced to compensate for the higher altitudes.

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
characteristics of the second brake are the same as the hoist motor brake. Both brakes are connected to
the same rectifier. This connection allows both brakes to open simultaneously, but the closing of the
second 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 protection rating of the second brake will match the protection rating of the hoist motor. The IP66
hoist motor protection option also upgrades the protection rating of the second brake when added.
29.2 Manual Brake Release for Trolley Motor – BRA05
A spring-loaded hand release is used to open the disc plates of the brake by hand. The brake release can
only be outfitted to the D.C. brakes. The brake release cannot be added to the Compact brake that is
used on most of the MF06 inverter-duty motors. In addition, the brake release cannot be used in outdoor
– no roof applications, or in high humidity or dust environments.
29.3 Manual Brake Release for Hoist Motor – BRA07
A spring-loaded hand release is used to open the disc plates of the brake by hand. The brake release is
also available for the second hoist brake - BRA01. The brake release cannot be used in outdoor – no roof
applications, or in high humidity or dust environments, and cannot be used on A-motors or S-motors.
29.4 Trolley, Double Girder High Connection – DES01
The high connection construction for the double girder trolley minimizes the hook to rail distance for better
headroom but the height of the trolley above the rail increases. More information is in the Trolley section.
29.5 Trolley, Double Girder Low Connection – DES01
The low connection construction for the double girder trolley minimizes the height of the trolley above the
rail for better overhead clearance, but it increases the hook to rail distance.
29.6 Control Transformer & Mainline Contactor – DES02
Electric Provision – EL05 replaces this feature (effective 2009).
29.7 Bumper Extensions between Trolleys – DES29
The bumper extensions are added to each hoist as needed when two hoists share a common beam or
girder. The extended bumpers would be added to ensure that the bumpers are the first point of contact
rather than any other part of the hoist.
29.8 Trolley, Special Flange Width for Low Headroom – DIM19
Hoist STANDARD Flange Width Range SPECIAL Flange Width Range
SX2/SX3 3.15” -16.14” [80 – 410 mm] 16.53” – 27.16” [420 – 690 mm]

29.10 Electric Provision – EL05
Value Description
CRANE The hoist controls will use the main line contactor and control voltage transformer in the bridge control
panel.
SOLO For monorail applications, the control transformer and mainline contactor will be added to the hoist
control panel. The control transformer and mainline contactor is an optional feature.
29.11 Special Encoder on Hoist – EL20
Special encoder on hoist is used for the ControlMaster Anti-Sway System. The encoder is mounted to
the rotary limit switch on the hoist and is needed to supply a signal back to the Height Measuring Unit.
HMU measures the position of the load block.
The Second Hoist Brake – BRA01 feature cannot be used when the special encoder is supplied on the
rotary limit switch.
29.12 Hoist Inverter Control Method – EL36
Value Description
Open loop Standard configuration for hoisting inverters ControlMaster TM Plus or ControlMaster TM Elite + T-motor
or ControlMaster TM Elite + A-motor
Closed loop Option for ControlMaster TM Elite VFD only with T-motor; Standard for CM Elite VFD + ESR
Hoist Inverter Control Method is in the Hoist Additional features in QuoteMaster ® .
29.13 Hoist without Electrical Controls – ELE65
This option omits the contactor hoist controls and it is typically used when the user consolidates the hoist
and trolley controls into one control enclosure. If omitting the controls, the hoist panel will include a wired
hoist brake rectifier as well as a terminal strip for the electrical leads for accessory items. Hoist motor and
limit switches leads are connected to terminals.
NOTE: This option does not apply to omitting the hoist inverter controls. It is highly recommended to
always use R&M’s ControlMaster TM inverters with R&M motors.
29.14 Transformer for Trolley Control – ELE68
This transformer is located in control panel to provide and maintain proper power to the trolley inverter
when needed. The power supply to R&M’s ControlMaster TM inverters must always be 460 volts-60 Hertz
(or 415 volts, 50 Hertz).
29.15 Bottom Side Drum Cover – GE24
Additional cover mounts to the bottom side of the hoist to cover the drum. The cover provides additional
protection against dust and/or dirt coming from below the hoist. The cover is available and only needed
for the SX2, SX3, SX4, and SX5 hoist models.
29.16 Hoist Motor, IP66 Protection – HM04
IP66 protection offers a special sealed motor and brake for humid and dusty conditions. IP66 protection
includes the motor and brake assembly. Hoist motors with external fans (MOT08) or with the manual
brake release (BRA07) cannot have the IP66 protection rating. Inverter-duty hoist motors for closed loop
system and the P8 hoist motor in particular cannot have the IP66 protection rating.
29.17 Hoist Motor, Thermal Protection – HM05
Klixon type bi-metal (PTO) switch in the hoist motor winding is standard. Motor operation will stop if motor
temperature rises above the permissible temperature rise. Alternate types of thermal protection devices
such as NTC thermistors or PTC thermistors are available through this option.

29.18 Hoist Motor, Class H Insulation – HM12
Class H motor insulation improves the heating capacity of the motor. Class H motors are often used for
special applications such as in high ambient temperatures applications or in heavy-duty use applications.
The maximum permissible temperature rise of the Class H motor is 125°C. Class F is the standard motor
insulation.
29.19 Speed Sensor on Hoist Motor – HM13
A speed sensor is required on the inverter hoist motor when the hoist motor control is inverter. The type
depends on whether the system is open loop or closed loop.
Code Description Inverter system
32 Bearing sensor on motor shaft, 32 pulses/rotation, Motors T1 – T3 ControlMaster TM inverter + open loop

29.20 Lockable Hook in Bottom Block – HOK02
The hook can be locked in one of four 90-degree positions. The lockable hook is available for most
bottom blocks, except for the 2-part single bottom block on the SX2 hoist.
NOTE: Headroom (C dimension) increases by 3” [75mm] from standard.
29.21 Heavy-weighted Bottom Block – HOK11
The bottom block is heavier in weight and has a lower center of mass to reduce the load sensitivity on the
hook bearing due to increase in friction as a result of dust in the working area. This bottom block is
available only for the SX2, SX3, SX4, and SX5 hoist models with 4-part single reeving. HBC style hook is
the standard.
NOTE: Headroom (C dimension) increases at least 5” [125mm] from standard.
29.22 Rain/Dust Cover for Hoist – HS04
Additional covers mount over hoist gearbox, hoist motor as needed, trolley drives, and hoist control panel.
Covers provide additional protection against rain or dust coming from above the hoist. Additional feature
Rain/Dust Cover for Trolley Motor – MOT10 does not to be added if this feature is already selected.
29.23 Hoist Drum Brake – HS07
The hoist drum brake can be added to the SX6 and SX7 hoists for additional safety - in addition to the
standard motor brake.
Adding the drum brake reduces the standard height of lift by 2 m or 6.5 ft. The height of lift is reduced
because some of the rope scoring on the drum (end opposite of the gear case) is removed so the brake
can be mounted there.
The drum brake consists of two separate brakes – a holding brake and an over-speed brake. The hoist
can be outfitted with both brakes, or with one or the other.
The holding brake, which is operated through a solenoid, holds the load when lifting or lowering has
stopped. The holding brake is for indoors only. The over-speed brake is a mechanical device that 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 activates. The over-speed brake can be used for indoors and
outdoors.
NOTE: The hoist drum brake feature cannot be added to hoists that use ASR or ESR inverter hoist
controls.

29.24 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 ® .
Adding a bypass switch to override the slack rope protection is highly recommended. The bypass switch
can be mounted on the pendant station 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.
29.25 Limit Switch, Hook Operated – HS22
The hook operated limit switch is used in conjunction with a rotary limit switch, which provides the upper
and lower limits on the SX2-SX7 models. The hook operated limit switch gets tripped by the hook block
moving in the up direction.
The hook operated limit switch is a safety device that shall not be used for the normal operation of the
hoist. The hook operated limit switch is wired in the control circuit and is a manual reset type. This means
the load block can be lowered if the limit switch happens to trip. But normal hoist operation (i.e. lifting) is
not possible until maintenance personnel resets the limit switch back to its normal operating position.
NOTES:
Adding the hook operated limit switch to the SX2-SX5 hoists will increase the headroom from standard
about 3 ½” to 11” [88-275 mm] depending on the hoist model. The offer drawing from QuoteMaster ® will
have the actual headroom dimension. If headroom is critical for the application, contact R&M to confirm
the accuracy of the headroom dimension.
Adding the hook operated limit switch to the SX6-SX7 hoists does not increase headroom.
29.26 Hard Chrome Shaft for Rope Guide – HS23
The guide shaft for the rope guide is chrome plated to reduce friction between the rope guide and shaft in
dusty environments. This option is only needed for SX2, SX3, SX4, or SX5 hoists.
29.27 Synchro for Hoisting – HS27
This feature controls all active hoist control drives so that the relative position of the hooks in a multiple
hoist operation stays at the same level. This feature requires inverter hoist controls. The inverters will
mount in the same control enclosure.
The leveling feature is designed for multi-hook hoist applications up to four similar hoists and is most
useful when the hoists are handling fixed or similar loads such as containers or long objects.
Synchro for Hoisting feature is required for tandem hoists using the ESR inverter hoist controls.
29.28 Load Limiter, Two-step – LIM07
This feature can include one intermediate load limit output and one overload limit output. It requires the
HoistMonitor ® .
29.29 Load Limiter, Three-step – LIM08
This feature can include two intermediate load limit outputs and one overload limit output. It requires the
HoistMonitor ® .
29.30 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.

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
Headroom is dimension C and lift is dimension H.
c_lim161a
Total reach is headroom (C) + lift (H).
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.

29.32 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. 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.
For more information about the standard setting, go to Hoist Limit Switch – Standard.

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

29.39 Hoist Motor External Fan – MOT08
The external fan is added to the IP55 hoist motor to improve the cooling. This means the hoist can be
used in conditions with higher than normal ambient temperatures (40 o C - 60 o C) without affecting the
motor performance. The fan starts automatically when the motor is energized and a timer relay in the
controls allows the fan to run 30 minutes after the motor is de-energized. The external motor fan should
not be used on hoists located outdoors.
NOTE: Adding the external fan to the hoist motor increases the overall length of the motor by 4” [100 mm].
The external fan is standard on the P8 hoist motor.
29.40 Rain/Dust Cover for Trolley Motor – MOT10
A rain/dust cover mounted over each trolley motor and gearbox. The cover provides additional protection
against rain/dust.
NOTE: This additional feature does not need to be added if the Rain/Dust Cover for Hoist – HS04 feature
is already added.
29.41 Anti-jump Catches for Double Girder Trolleys – OTH23
The anti-jump catches can be added to top running double girder trolley to prevent the trolley from leaving
the rail. The catches are bolted to the end plates of the end trucks. The anti-jump catches for double

29.59 Anti-collision Device for Trolley – TR16
The anti-collision device prevents two trolleys on the same bridge from approaching each other at a high
rate of speed.
The anti-collision device consists of a photocell sensor and reflector. The reflector is placed on the
opposite trolley directly across from the sensor. The maximum traveling speed is 105 fpm [32 m/min].
It is not necessary to specify the location of the device on the trolley. The device is shipped loose, and
then mounted to the trolley by others.
There are three modes of operation to choose from when specifying the anti-collision device.
• Slow down mode - the trolley can only be driven in slow speed when the trolley is within the
sensing distance. It requires one photocell sensor and reflector on each trolley in one direction.
• Slow down + stop modes - the trolley drive drops out of fast speed and into slow speed, and
then the trolley stops when the trolley is within the sensing distance. It requires a photocell sensor
and reflector for each mode of operation (one for slowdown + one for stop) on each trolley in one
direction.
• Stop mode - the trolley stops traveling regardless of the speed when the trolley is within the
sensing distance. It requires one photocell sensor and reflector on each trolley in one direction.

HOIST SPEED ACCURACY: The actual hoist speed of hoist units with the same nominal speed but with
a different reeving system, gearing ratios, and motor types could vary ±15%. Better speed accuracy can
be attained through VFD (inverter) controls where the speeds of both hoists can be fine-tuned through the
inverter parameters. Exact matching speeds could be important for hoists that would operate together.

32 Crane Festoon System
The festoon system comes complete with a plug and play cables (Exceptions apply - see Plug Rules
section), galvanized c-track, and cable trolleys as well as all the necessary hardware needed to supply
power to the hoist/trolley and bridge drives. The electrification package also includes the crane collector
arm, hoist tow arm, bumper end stops for hoist (single girder cranes only), and the sticker sets.
The pendant is suspended from a cable trolley that rides on its own, separate c-track. The hoist/trolley
power cables and control cables are suspended from cable trolleys that ride on two other tracks. The
festoon cable lengths are pre-engineered for a six-foot [1828.8mm] cable trolley pitch for the specified
span. Other pitch lengths are available at one-foot intervals. The c-track system is a bolt-together
construction.
32.1 Support Rail Mounting
The connection method of the cross-arm support rails depends on the crane type. Bolt-on beam clamps
fasten the support rails to the I-beam or box girder of a single girder crane. As for double girder cranes,
the suspension support brackets are welded to the girder on the underside of the top flange and the
support rails are then bolted to the brackets.

33 NRGmaster Electrification System
NRGmaster electrification system supplies power to the hoist, and to the bridge drives. It is an alternative
to the festoon system.
NRGmaster is for wire rope hoist cranes that are located indoors or outdoors if under roof. NRGmaster
cannot be used on cranes with chain hoists, in extreme ambient temperature conditions, in high dust
areas, outdoors (no roof), or in hazardous locations.
The power and control cables are enclosed in a flexible chain. A guide channel supports the flexible chain
and fastens to the bridge girder. The free end of the chain bends into a U-shape and connects to the hoist
tow arm while the other end fastens to the channel. The cables for the bridge motors run in a separate
raceway, located behind or below the guide channel. The electrification package also includes the crane
collector arm, hoist tow arm, bumper end stops for hoist (single girder cranes only), and the sticker sets.
33.1 Cables
The hoist power and control cables as well as the bridge motor cables are furnished with plugs for quick
cable connection. Exceptions apply. See the Plug Rules section. Cables without plugs will use cable
glands and have to be hardwired.
33.2 Controller
Radio control plus a backup pendant is standard with NRGmaster. Radio control must always be used
with NRGmaster since the number of conductors in the control cable is optimized for the radio and not for
the pendant. The pendant connects directly to the bridge panel and is not moveable. A moveable pendant
is not an option with NRGmaster.
33.3 Bridge Girder Selection
The size of the chain and the location of the guide channel for a particular trolley type might affect the
bridge girder selection in order to meet a minimum flange width or a minimum beam height requirement.
Before selecting another beam, look at the minimum flange width and minimum depth requirements. Key
dimensions for NRGmaster will also be part of the DAS-generated crane layout drawing in QuoteMaster ® .

36 Plug Rules
The plug rules below are for reference and apply to hoists or cranes that are located indoor and have
control panels rated IP55 or equivalent.
Plug kits are not available when the control enclosures are stainless steel with an IP66 rating.
36.1 Control Cables
The pendant cable for SX2-SX7 hoists is furnished with a plug.
Plugs are usually supplied on the hoist control cable that connects to the hoist and bridge panels but
there are exceptions. Hoist control cables do not come with plugs and must be hardwired whenever the
inverter motor type for the hoist is T5 or larger, the control panel type is KA220, or the hoist type is a SX7.
The KA220 control panel is generally used for the bigger inverter hoist controls and for some two-speed
hoist controls.
The pulse sensor cable, which runs from the inverter to the pulse sensor on the motor, is hardwired (no
plugs). The CAN-bus cable that connects to the HoistMonitor ® is hardwired (no plugs).
36.2 Power Cables
The plug rules below apply for two-speed hoist motors (P1…P8).
Plugs are supplied on the hoist power cable that connects to the hoist and bridge panels when the hoist
motor type is P1. No plug restrictions with regards to the span and power supply voltage.
Plugs are supplied on the hoist power cable that connects to the hoist and bridge panels when the hoist
motor type is P2 or P3 except when the span is over 65 ft [19.8m] and the power supply is 208 or 230
volts.
Plugs are supplied on the hoist power cable that connects to the hoist and bridge panels when the hoist
motor type is P4 or P5 and power supply is greater than 230 volts. Plugs for the hoist power cables are
not supplied when the power supply is 208 or 230 volts.
Plugs are supplied on the hoist power cable that connects to the hoist and bridge panels when the hoist
motor type is P6 or P7 and the crane span is less than or equal to 55 feet [17m] and the power supply is
greater than 230 volts. Plugs for the hoist power cables are not supplied when the power supply is 208 or
230 volts.
Plugs are not supplied for the hoist power cables when the hoist motor type is P8 or when two hoists
motors are used (2 x P6, 2 x P7, etc) for the SX7 hoists.
Cables supplied without plug connectors have to be hard wired connected.

36.3 Plug Kits and Stainless Steel Enclosures
Plug kits are not available when the control enclosures are stainless steel with an IP66 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 IP55 rating. The same plug kit rules for the
standard enclosures apply to the stainless steel enclosures with the IP55 rating.
37 Bridge Girder
The type of bridge girders that is suggested from the QuoteMaster ® 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: R&M does not supply the bridge girder. 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 width of the suggested bridge beam or for a
predetermined flange width.
38 Tandem Hoists
Tandem hoists are defined as “two similar” hoist/trolley models, which have similar speeds, reeving, gear
and motor types, operating in tandem or independently.
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 three-position selector switch, a
two-position selector switch or an extra set of hoist buttons are optional control features.
Tandem controls in the bridge panel
ESR inverter hoist controls (S motor) require the Synchro for hoisting (HS27) feature
HoistMonitor ®
The use of a three-position selector switch will allow the operator to operate the hoists independently or
together. The two-position selector switch can only be used for independent hoist control.
HOIST SPEED ACCURACY: The actual hoist speed of hoist units with the same nominal speed but with
a different reeving system, gearing ratios, and motor types could vary ±15%. Better speed accuracy can
be attained through VFD (inverter) controls where the speeds of both hoists can be fine-tuned through the
inverter parameters. Exact matching speeds could be important for hoists that would operate together.
NOTE: ASR inverter hoist controls with A-motors cannot be used in tandem hoists configurations.

39 Crane Options
39.1 Thermal Protection for Bridge Motor – BM08
The thermal protection device is a cut-off bi-metal switch located in the motor. Motor operation will stop if
motor temperature rises above the permissible temperature rise.
39.2 Bridge Motor, IP66 Protection – BM09
IP66 protection offers 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.
39.3 Bridge Motor, Class H Insulation – BM11
Class H motor insulation improves the heating capacity of the motor. Class H motors are often used for
special applications such as in high ambient temperatures or heavy-duty use applications. The maximum
permissible temperature rise of the Class H motor is 125°C. Class F is the standard motor insulation.
39.4 Manual Brake Release for Bridge Motor – BRA06
A spring-loaded hand release is used to open the disc plates of the brake by hand. The brake release can
only be outfitted to the D.C. brakes. The brake release cannot be added to the Compact brake that is
used on most of the MF06 inverter-duty motors. In addition, the brake release cannot be used in outdoor
– no roof applications, in high humidity or dust environments.
39.5 Anti-collision Device for Second Crane – BT20
Anti-collision device for second crane is for an existing crane that is already on the runway for 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].
39.6 Rubber Cables for Hoist Power Supply – CBL07
PVC flat cables for the hoist power supply are replaced with Neoprene (rubber) flat cables for better
lifetime of the cables against the rain, heat, cold, and sunlight.
39.7 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. The maximum extension length is 40 inches [1 m].
39.8 Insulation for Bridge Panel – EL23
Insulation for the bridge panel can be added when crane is used in high or low ambient temperature
applications. The insulation option is limited to the EF, KA220, and H15 enclosure types.
39.9 Thermostat Controlled Heating – EL24
Thermostat controlled heating device controls the temperature inside the bridge panel. The heating
device is added to the bridge panel if the crane is going to be operated in low temperature conditions
where the ambient temperature is below 14 o F [-10 o C]. The hoist, trolley, and bridge controls are mounted
in the bridge panel. The heating device will keep the temperature inside the panel above 32 o F [0 o C].
39.10 Bridge Panel Lights – EL25
Fluorescent light can be mounted inside the bridge panel with manual or automatic door switch.
NOTE: Available for EF, KA220 and H15 panels.
39.11 Rain Cover for Bridge Panel – EL26
The rain cover for bridge panel provides additional protection against rain, dust, and direct sunlight.

39.13 Indicator Beacon for Crane – EL52
Indicator beacon for crane is a continuous red light to indicate that the radio control is activated. It is
mandatory in most European countries. (This beacon is not a substitute for a flashing light to indicate
traveling movement. Use feature ELE98.)
39.14 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.
Volts Amps Volt-Amperes Nominal Coil Resistance
120V 50/60Hz 0.22/0.18 21.6 68.0
39.15 All Electrics in Bridge Panel – ELE10
All controls are consolidated in the bridge panel when needed.
39.16 Flashing Light for Traveling – ELE20 (replaced by ELE98)
Warning Indication for Traveling Movement – ELE98 replaces this option (effective late 2007).
39.17 Pliotex Type Wire Marking – ELE48
Pliotex type wire marking is a plastic marker with one character in it. These markers are permanent and
they can be used where high humidity is present.
39.18 Crane Lights (Provision only) – ELE61
Provision for crane lights can be added to the crane package. How the lights will be controlled, how many
lights, and the voltage for the lights must be defined in order to include the provision. The lights can be
controlled either by an extra button or through the “START” button on the controller. The maximum
number of lights for the provision is six. The watts/voltage for the lights can be 400W/115v, 400W/230v,
or 400W/Power supply voltage.
39.19 Limit Switch, Hook-Operated, Trips Mainline Contactor – ELE64
The hook-operated limit switch (HS22) will be wired to the mainline contactor circuit rather than to the
hoisting circuit. If the hook-operated limit switch is tripped, the mainline contactor will shut off power to the
entire crane. To restore power to the crane, press the START button on the pendant after manually
resetting the hook-operated limit switch.
NOTE: The hook operated limit switch must be added to the hoist as a separate option. Adding the hook
operated limit switch to the SX2-SX5 hoists will increase the headroom from standard about 3 ½” to 11”
[88-275 mm], depending on the hoist model. The offer drawing from QuoteMaster ® will have the actual
headroom dimension. If headroom is critical for the application, contact R&M to confirm the accuracy of
the headroom dimension.

39.20 Transformer for Entire Crane – ELE67
The autotransformer for the entire crane is needed to supply proper power to the controls when a hoist
inverter is used and the power supply is something other than 460 volts - 60 Hz (or 415 volts - 50 Hz).
39.21 Transformer for Bridge Control – ELE69
This transformer is located in bridge control panel to provide and maintain proper power to the bridge
inverter when needed. The power supply to R&M’s ControlMaster TM inverters must always be 460 volts -
60 Hz (or 415 volts - 50 Hz).
39.22 Warning Indication for Traveling Movement – ELE98
The warning indication comes as a flashing light or as a beeper, or the light and beeper can be combined
into one module when needed. The protection rating of the device is IP66. The warning device is used to
warn people that the crane or trolley is moving depending on how the device is activated.

39.23 Special Lubrication for Gears – GE21
The standard lubricant is replaced with a synthetic lubricant if the crane is going to be operated in low
temperature conditions where the ambient temperature is usually below 14°F [-10°C] or in high
temperature conditions where the ambient temperature is usually above 104°F [40°C].
39.24 Load Display – HS09
A load display will show the load of the hoist. For multiple hoists, the load display will show only the total
load of all the hoists (up to five hoists). Total load is the sum of the individual hoist loads. See feature
HS28 if the display of individual load is also needed (for two hoists only).
The load display shall not be used as a calibrated weighing scale. The accuracy of the displayed load
value is approximately ±5%. The height of the LED characters on the display is about 100 mm. The load
display typically mounts on the bridge near the bridge panel.
The load display feature requires the HoistMonitor ® with the strain gauge overload.
39.25 Load Display for Total or Individual Load – HS28
This feature is for two hoists only. A single load display will show either the total load of both hoists or the
individual load of either hoist. This is done by adjusting the position of the selector switch (I, I+II, II).
Note: Load Display - HS09 feature must also be defined to use this feature.
39.26 Limit Switch, Bridge Traveling Two-step (Slowdown + Stop) – LIM12
This features changes fast bridge speed to slow speed when the switch is 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. Standard feature on crane packages starting in April, 2011.
39.27 Nonstandard Voltage/frequency for Crane
Standard voltages: 208v/230v/460v/575v – 3ph – 60Hz. Other voltages are available on request.

39.28 Standby Heater for Bridge Motor – MOT17
Heaters are furnished to prevent condensation building up on the motor windings during prolonged
periods of idleness. The heaters operate on single-phase current only.

39.29 Rain/Dust Cover for Bridge Motor – MOT18
The rain/dust cover over each bridge motor and gearbox provides additional protection against rain/dust.
39.30 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 photocell sensor and reflector. The reflector is placed on the
opposite crane directly across from the sensor. The maximum traveling speed is 100 fpm [32 m/min].
It is not important to specify the actual side of the crane the device will be located. (The anti-collision
device is shipped loose.) However, it is important to specify the type of photocell and whether the anticollision
device is needed in one direction or two directions for that crane. For example, when there are
two cranes on the runway, a sensor and a reflector is needed on one side, (one side = one direction) of
each crane. In another example, when there are three or more cranes on the runway, a sensor and a
reflector is needed on both sides (both sides = both directions) of the middle crane(s), and a sensor and a
reflector is needed on one side of the cranes on the ends of the runway.
There are three operation modes to choose from when specifying the anti-collision device.
• Slow down mode - the bridge can only travel in slow speed when the crane is within the sensing
distance. It requires one photocell sensor and reflector on each crane per direction as needed.
• Slow down + stop modes - the bridge drive drops out of fast speed and into slow speed, and
then the crane stops when the crane is within the sensing distance. It requires a photocell sensor
and reflector for each mode of operation (one for slowdown + one for stop) on each crane per
direction as needed.
• Stop mode - the crane stops traveling regardless of the speed when the trolley is within the
sensing distance. It requires one photocell sensor and reflector on each crane per direction as
needed.

39.31 Rail Sweeps – OTH21
Wooden rail sweeps are bolted to the end plate of the top running end trucks. Rail sweeps are added if
the runway rails can be covered with snow or dust. A steel brush is used for harder material on the rails.
The length of the rail sweep is defined in the table below.
End truck Length (mm) Length (inch)

39.32 Storm Locks – OTH22
Storm locks are usually added if the crane cannot be parked safely due to the wind. The storm lock
includes a switch to lock out the crane controls when the locking device is engaged.
The storm lock is mounted on each truck near the drive wheel and to the span side of the crane if the side
is not specified. The position of the storm locks is not adjustable so it is important to advise the SL1
dimension needed for the application, otherwise the storm lock will be place at the minimum SL1 distance
for the selected end truck model. The minimum SL1 distances for the various end truck models are
defined in table below. The minimum SL1 distance listed in the table do not apply to gantry crane trucks.

39.33 Anti-jump Catches for Crane – OTH24
The anti-jump catches can be added to top running end trucks to prevent the crane from jumping the rail
due to wind or if the runway rail can be covered with snow or ice. Two catches are bolted to the span side
of each end truck near the wheels.
Anti-jump catches for end truck models RTN20-RTN32, RT50 are not adjustable so it is important to
advise dimensions L1 and L2 to properly size the catches. Dimension L1 is measuring the thickness of
the runway beam plus the height of the runway rail, and dimension L2 is measuring from the center of the
rail to the edge of the beam flange.

39.34 Stainless Steel Bridge Panel (IP55) – PAN04
The IP55-rated stainless steel panel gives a degree of protection against corrosion.
Plug kits for the cable connections are furnished only for IP55-rated stainless steel enclosure if the plug
kit rules apply to the standard enclosure. Cable glands are used in place of plugs.
Note: To get an IP66-rated stainless steel panel, select Stainless Steel Bridge Panel (PAN04) and the IPtype
of Bridge Panel (PAN07). Exclusions apply. Use QuoteMaster ® or contact R&M for assistance.
39.35 IP-type of Bridge Panel (Add for IP66) – PAN07
The IP66 protection rating can be added to the control panel to give better protection against dust or high
humidity. Plug kits are not furnished on panels rated IP66. Power and control cables are hardwired to
terminal strips, and cable glands are used to seal the cable entries.
The KA220 and H15 enclosures do not have IP66 protection rating available. The IP rating
of these enclosures is IP54/IP21 and the panel is identified in QuoteMaster ® as “enclosed”.
The IP21 side of the enclosure has vents that allow the air to circulate for cooling the
dynamic braking resistors.
KA220/H15 panel
39.36 Standby Heater for Bridge Control Panel – PAN08
Heater provides additional protection against moisture in cold or humid conditions. The standby heater in
bridge panel cannot be used in combination with the thermostat controlled heating device – EL24.
39.37 Plug Source in Bridge Panel – PAN17
This option provides the transformer and protection for up to three single-phase plug outlets in the bridge
control panel. The 115VAC, 16A plug outlet is not furnished; it is supplied and mounted by others. IECtype
plug outlet and/or 230VAC plug outlet voltage can be furnished in lieu of 115VAC.
39.38 Standby Heater for Pendant Enclosure – PEN03
Heater provides additional protection against moisture in cold or humid conditions.
39.39 Contactor Control, Bridge – PRI01
Two-speed contactor control replaces the variable frequency drive, which is standard equipment. The
contactor is the IEC type.
39.40 Display in Radio Transmitter – REM20
Adds display to RaCon or RaCon II radio transmitter.
39.41 Longer Chain for Trolley Tow Arm & Festoon – PS05
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.
39.42 Crane Sticker Set – ST09
The set includes two load stickers, one direction symbols sticker, and four bolt tightening instruction
stickers in English. The load stickers are available three different sizes – height of 127 mm, 238 mm, or
330 mm.
39.43 Sticker Set – ST11
The sticker set includes two SWAY CONTROLLED CRANE stickers. The stickers mount to the bridge
girder to clearly point out the crane feature.

39.44 ControlMaster TM Anti-Sway System – DP01
ControlMaster TM Anti-Sway System is designed to prevent load swing. The anti-sway system can be
selected for trolley traveling or bridge traveling, or for both. It can be added to cranes with one hoist or
two similar hoists. The anti-sway system cannot be used for any other hoist combinations such as
main/auxiliary hoist applications, or for lifts greater than 131 ft [40 m].
The ControlMaster TM Elite inverter for travelling is required with the ControlMaster TM Anti-Sway System.
The control method for the inverters will be setup for two-speed (MS2). The ratio between fast speed and
slow speed is programmed for four to one (4:1).
Other components for the anti-sway system include the height measuring unit, height sensor (encoder) –
EL20, activation light (amber), hook operated limit switch – HS22, sticker set – ST11, and the RaCon ®
radio control.
The traveling inverters and the height measuring unit are mounted in the bridge panel. The activation light
is supplied loose and mounts on the crane. The encoder is mounted to the back end of the rotary
(geared) limit switch on the hoist. The encoder is completely wired and the shielded cable leads are
terminated in the hoist panel. Shielded cable is also used to send the encoder signal back to the height
measuring unit in the bridge panel. The shielded cable and grounding hardware will be supplied in the
hoist electrification package. The SWAY CONTROLLED CRANE stickers mount to the bridge girder(s) to
clearly point out the crane feature. The hook operated limit switch – HS22 is included for back up.
RaCon ® radio control, outfitted with the sling length adjustment switch, must
operate the crane with the anti-sway system. A backup pendant can be
provided but the anti-sway system cannot function from the pendant. Sway
control for a crane with one hoist will use the pushbutton transmitter. Sway
control for a crane with two similar hoists will use the joystick transmitter that
will also include the hoist selector switch (I, I+II, II). A display for the
HoistMonitor ® can be added to either one of the radio transmitters.
ControlMaster TM Anti-Sway System corrects the movements of the trolley
and bridge inverters based on a mathematical model using the swing time
principle. The load swing can be predicted by the swing time, which is
directly related to the pendulum length. The pendulum length is measured
from the center of the rope drum to the center of gravity of the lifted load.
The height measuring unit measures the pendulum length as it varies when
the load is lifted or lowered. The sling length (from hook to center of gravity
of load) must also be included in the pendulum length. The crane operator
can adjust for different sling lengths by dialing in the sling length adjustment
switch on the radio control. The switch can also turn off the sway control
system.
