Form MHD56331 Edition 1
When released, handle will return to the neutral or center position. Fold the handle
down to engage and lock the control handle in place.
Remote Live Full Flow Air Throttle (optional feature)
Provides for remote mounting of winch control at a fixed location at up to 20 feet (6
metres) away from winch motor. Air hoses connect throttle to winch motor to
provide winch operation.
Move control throttle handle to the right (clockwise) to payout wire rope and to the
left (counterclockwise) to haul-in wire rope. Avoid sudden movements of control
valve to ensure smooth operation of winch.
Remote Pilot Pendant Throttle (optional feature)
Refer to Dwg. MHP0204.
Provides for remote winch control at distances of up to 66* feet (20 metres) away
from winch. The pilot pendant control throttle is a two function movable control
station for winch operation. Pilot pressure from pendant control activates winch
control valve. The winch control valve, located on winch motor, controls motor speed
and direction of drum rotation. Direction of drum rotation is determined by the
pendant lever/button depressed.
Remote Pilot Lever Throttle (optional feature)
Provides for remote winch control at distances of up to 66* feet (20 metres) away
from winch. The lever pilot control throttle is a fixed mounted lever control station
for winch operation. Pilot pressure from lever pilot control throttle activates winch
control valve. The winch control valve, located on winch motor, controls motor speed
and direction of drum rotation. Direction of drum rotation is determined by the
direction in which lever is shifted.
* For distances greater than 66 feet (20 metres) contact

Winch Brakes
Manual Band Brake
Refer to Dwgs. MHP0152 and MHP0209.
The manual brake may be applied by pushing down on handle and released by pulling
up. If handle is pushed down fully, it should lock in that position and prevent drum
rotation, until released by operator. The brake must be kept properly adjusted to
hold required load. Refer to ‘Adjustments’ in “MAINTENANCE” section in Product
Maintenance Information Manual Form MHD56332 for adjustment instructions.
Automatic Band Brake (optional feature)
The automatic brake is a spring applied, air released brake which utilizes an air
actuated, spring loaded cylinder, that automatically disengages brake when motor is
operated. Air pressure in cylinder overcomes spring pressure to release brake. When
control valve is placed in neutral position, air in cylinder is vented and spring
automatically engages brake to prevent drum rotation.
The cylinder clevis must be kept properly adjusted to hold required load.
Automatic Disc Brake
The automatic brake is a spring applied, air released brake. Using an air actuated,
spring loaded piston, the brake automatically disengages when motor is operated
and engages when throttle is returned to neutral position.
Air pressure ported through brake housing overcomes spring pressure and moves
piston which releases brake. When control valve is placed in neutral position, air is
vented, spring pressure overcomes air pressure and spring pressure moves piston,
engages brake and prevents drum rotation.
Limit Switch
Pre-set limit switch settings prevent winch wire rope payout and haul-in by stopping
air flow to the winch motor when a set point has been reached. It is the owner’s and
operator’s responsibility to adjust winch operating limits prior to using the winch. To
adjust the limit switch set points, refer to “INSTALLATION” section on page 4.
Press Roller (optional feature)
Ensure wire rope is positioned between press roller and drum barrel and springs keep
press roller in tight contact with wire rope.
Slack Wire Rope Detector (optional feature)
Contact factory for information.
INSPECTION
Inspection information is based in part on American National Standards Institute
Safety Codes A10.22 and American Standards of Mechanical Engineers Safety Codes
B30.7.
WARNING
• All new or repaired equipment should be inspected and tested by
Ingersoll-Rand trained Service Technicians to ensure safe operation at rated
specifications before placing equipment in service.
• Never use a winch that inspection indicates is damaged.
Frequent and periodic inspections should be performed on equipment in regular
service. Frequent inspections are visual examinations performed by operators or
Ingersoll-Rand
trained Inspectors and include observations made during routine
equipment operation. Periodic inspections are thorough inspections conducted by
Ingersoll-Rand
trained Service Technicians. ASME B30.7 states inspection intervals
depend upon the nature of the critical components of the equipment and the severity
of usage. Refer to ‘Inspection Classifications’ chart and ‘Maintenance Intervals’ chart
in Product Maintenance Information Manual Form MHD56332 for recommended
maintenance intervals.
Careful inspection on a regular basis will reveal potentially dangerous conditions
while still in the early stages, allowing corrective action to be taken before the
condition becomes dangerous.
Deficiencies revealed through inspection, or noted during operation, must be
reported to designated personnel to ensure corrective action is taken.
A determination as to whether a condition constitutes a safety hazard(s) must be
decided, and the correction of noted safety hazard(s) accomplished and documented
by written report before placing the equipment in service.
Records and Reports
Personnel Lifting System
Owners are responsible for establishing and implementing operation and safety
procedure training for all personnel involved in the use and operation of a Personnel
Lifting System.
1. PERSONNEL TRAINING. Records of training provided to supervisors, operators,
service personnel and personnel being transported should be maintained and
made available to designated personnel for review.
2. SYSTEM MAINTENANCE. Records of all service, maintenance and testing
performed on the Personnel Lifting System should be maintained and made
available to designated personnel for review.
Winch Records and Reports
Inspection records, listing all points requiring inspection, should be maintained for
all load bearing equipment. Written reports, based on
Initial
,
Weekly
and
Quarterly
inspections, should be made on the condition of critical parts as a method of
documenting inspections. These reports should be dated, signed by the person who
supervised the performance of the inspection, and kept on file where they are readily
available for review. A sample winch ‘Inspection and Maintenance Report’ has been
provided in the Product Maintenance Information Manual Form MHD56332.
Wire Rope Reports
Records should be maintained as part of a long-range wire rope inspection program.
Records should include the condition of wire rope removed from service. Accurate
records will establish a relationship between visual observations noted during
frequent inspections and the actual condition of wire rope as determined by periodic
inspections.
Personnel Lifting System wire rope records should be maintained and made available
to designated personnel for review.
System Inspections and Tests
WARNING
• Information provided by Ingersoll-Rand is applicable only to the winch to
assist in determining the condition of the winch components described.
References to other Personnel Lifting System components are made with respect
to their relationship to the winch. For specific information on system
components other than the winch, reference the manufacturer’s literature and
ANSI A10.22.
Personnel Lifting System inspections and tests of installed components, functions
and safety devices should be established based on procedures derived from ANSI
A10.22 specifications, OSHA regulations, manufacturer’s literature and
recommendations, system designer recommendations and all applicable local, state
and national standards.
1. SYSTEM. Frequency of inspections:
a.
Initial system inspection.
b.
Daily checks and Weekly inspections.
