Winch Use, Operation, and
Maintenance—Manual
Prior to Use
•
Inspect rope or cable, and replace if damaged.
•
Inspect mounting hardware for correct tightness.
Torque if necessary.
•
Gears, ratchet pivot point, and shaft bushings must
be kept lubricated with a thin film of oil or grease.
Operation
Raising the Lights:
1.
Verify the cable is securely fastened to the object
being lifted and to the winch drum.
2.
Verify the cable and cable attachments are not
damaged. Contact a GMP ASD to order a replace-
ment cable if necessary.
3.
Referring to the “Lift / Let Down” decal on the
winch, turn handle according to the specified direc-
tion to lift. The ratchet MUST make a loud clicking
sound while winding the cable.
Lowering the Lights:
Referring to the “Lift / Let Down” decal on the winch, turn
handle according to the specified direction to lower. No
clicking will be heard because the brake system is acti-
vated.
Maintenance
The following procedures should be performed at least
annually:
1.
The gears and bushings of the winch must be kept
lubricated. Apply a thin film of grease to the gear
teeth, and oil the bushings as needed.
2.
The ratchet pawl pivot point must be kept lubri-
cated with a thin oil.
NOTE:
Do not get oil or grease on the brake mechanism.
Winch Use, Operation, and
Maintenance—Electric
•
Keep the winch free of dirt, oil, grease, water, and
other substances.
•
Inspect all mounting bolts and verify they are tight-
ened to the recommended torque values. Replace
any damaged fasteners.
•
Periodically inspect all connections to verify they
are tight and free of corrosion.
•
Inspect 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 the
winch drum continues to turn after controls are
released, the brake may need to be replaced.
•
Periodically clean and grease the brake assembly
to 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.
•
Inspect motor brushes periodically and replace
when necessary.
NOTE:
Only the motor brushes and brake assembly
require periodic replacement.
