TROUBLE

PROBABLE CAUSE

REMEDY

C

The brake will not hold a load
with the control lever in neutral.

1. Excessive system back pressure

acting on the brake release port.

2. Friction brake will not hold due to

worn or damaged brake discs.

3. Brake clutch is slipping.

The same as Remedy 2 of Trouble B2.

Same as Remedy 3 of Trouble A3.

Improper planetary gear oil may cause the
brake clutch to slip. Drain old gear oil and
fl ush winch with solvent. Thoroughly drain
solvent and refi ll winch with recommend-
ed planetary gear oil listed in “Preventive
Maintenance”.

Brake clutch may be damaged or worn.
Disassemble and inspect brake clutch as
described in “Brake Clutch Service”.

D

The winch will not hoist the
rated load.

1. The winch may be mounted on an

uneven or fl exible surface which
causes distortion of the winch
base and binding of the gear train.
Binding in the gear train will ab-
sorb horsepower needed to hoist
the rated load and cause heat.

2. System relief valve may be set too

low. Relief valve needs adjustment
or repair

3. Be certain hydraulic system tem-

perature is not more than 180
degrees F. Excessive hydraulic
oil temperatures increase motor
internal leakage and reduce motor
performance.

4. Winch line pull rating is based on

1st layer of wire rope.

5. Rigging and sheaves not operating

effi ciently.

Reinforce mounting surface.

If necessary, use shim stock to level winch.
Refer to “Winch Installation”.

First loosen, then evenly retighten all winch
mounting bolts to recommended torque.

Check relief pressure as follows:

A. Install an accurate 0-4000 psi (27,580
kPa) gauge into the inlet port of the brake
valve.

B. Apply a stall pull load on the winch while
monitoring pressure.

C. Compare gauge reading to winch speci-
fi cations. Adjust relief valve as required.

NOTE: If pressure does not increase in
proportion to adjustment, relief valve may
be contaminated or worn out. In either case,
the relief valve may require disassembly or
replacement.

Refer to winch performance charts for ad-
ditional information.

Perform rigging service as recommended
by crane manufacturer.
