Overload Device

Optional feature. An overload device is available on winches
provided with the emergency shut-off valve. Overload device
operation is based on the differential pressure between the motor
inlet and exhaust. The overload device is factory preset to
actuate at 150% (+/- 25%) of rated capacity of the winch. When
an overload condition is sensed air is directed to the emergency
shut-off valve to isolate air to the winch.
If the overload device is activated the load must be reduced.
Reset the Emergency Stop Valve and operate the winch in the
payout direction to lower the load.

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 described in the
“MAINTENANCE” section of this manual. Failure to
correctly install the friction and separator plates can cause
injury and/or property damage.

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.
Minor adjustments 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.

Manual Drum Brake

Refer to Dwg. MHP1449.
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.
