Winch Mechanical Brake
The mechanical brake generates heat when loads are
lowered and the wire cable is powered out. Avoid
overheating the mechanical brake.
Whine or chatter associated with a new mechanical
brake is normal and typically disappears with use.
Overheating the mechanical brake may result in
permanent damage to, or failure of, the brake. Replace
003784
any damaged brake components before resuming use of
the winch.
After First
Operation
•
Check all mounting bolts and make sure they are
tightened to the recommended torque values.
Replace any damaged fasteners.
•
Periodically check all connections to be sure they
are tight and free of corrosion.
•
Check the cable for visible damage every time the
winch is operated. Examples of damage are: cuts,
knots, crushed or frayed portions, and broken
strands. Replace cable immediately if damaged.
Failure to replace a damaged cable could result in
breakage.
•
Regularly check the brake for slippage or drift. This
is detected visually when winch is under load. If
winch drum continues to turn after controls are
released, the brake may need to be replaced.
•
Periodically clean and grease the brake assembly.
This will ensure proper performance and extend
the life of the winch. If winch seems to labor or get
excessively hot during the lowering of loads, the
brake will need to be serviced or replaced.
•
Check motor brushes periodically and replace
when necessary.
