3. To throttle operating speed regulate the amount the lever is
depressed. Depress lever completely for maximum speed;
depress lever partially for slower speeds.
4. To stop haul-in or payout operation release the lever. Lever
will spring return to off and winch motor will stop.
NOTICE
• Pendant haul-in and payout levers provide variable speed
operation. For low speed operation push appropriate lever
slightly; for full speed operation push appropriate lever fully.
* To ensure accurate winch control when remotely operating the
winch at distances greater than 60 feet (18 metres) contact
Ingersoll-Rand Technical Sales for control suitability.
Pendant Operation
(Dwg. MHP1311)
Winch Brakes
Automatic Disc Brake
The automatic disc brake is a spring applied, air released brake.
When the winch is operated in the payout direction air pressure
acting on the diaphragm overcomes spring pressure and releases
the brake. The brake automatically engages when winch
operation is returned from the payout direction to neutral or
when shifted to the haul-in direction. When the winch is in the
neutral or haul-in positions the brake air is vented and the brake
springs apply the brake. The springs, acting on the pressure
plate, compress the brake friction and separator plates and
engage the brake to prevent drum rotation in the payout
direction.
The cam type sprag clutch assembly allows drum rotation in the
haul-in direction with the brake plates engaged, but prevents the
drum from rotating in the payout direction.
Disc brake adjustment is not required. If the disc brake does not
operate properly it must be disassembled, inspected and
repaired.
WARNING
• If the brake is disassembled, the friction and separator
plates must be correctly installed as shown in the
“MAINTENANCE” section of this manual. Failure to
correctly install the friction and separator plates can cause
injury and/or property damage.
Manual Drum Brake
Refer to Dwg. MHP1375.
The manual drum brake may be applied by pushing down on the
handle (135) and released by pulling up. By pushing the handle
down fully it will go over-center and lock in that position,
preventing drum rotation. The drum brake must be kept properly
adjusted to hold the required load. Refer to ‘Adjustments’ in the
“MAINTENANCE” section. If brake band cannot be adjusted to
hold the rated load, the brake must be disassembled, inspected
and repaired.
Drum Brake Handle Operation
(Dwg. MHP1375)
Automatic Drum Brake
Optional feature. The automatic drum brake is a spring applied,
air released, externally mounted brake which uses an air
actuated, spring loaded cylinder to automatically disengage the
brake when the motor is operated in either the haul-in or payout
directions. Air pressure directed to the cylinder overcomes
spring pressure to release the brake and allow the drum to rotate.
When the control valve is placed in the neutral position, the air
in the cylinder is vented which allows the cylinder spring to
automatically engage the brake and prevent drum rotation.
Adjustments to the cylinder clevis can be made to compensate
for normal brake lining wear. The drum brake must be kept
properly adjusted to hold the required load. Refer to
‘Adjustments’ in the “MAINTENANCE” section. If brake band
cannot be adjusted to hold rated load, the brake must be
disassembled, inspected and repaired.
