E
The winch runs hot. 1. Same as D1.
2. Be certain that the hydraulic system tem-
perature is not more than 180
°
F (82
°C)
.
Excessive hydraulic oil temperatures may
be caused by:
A. Plugged heat exchanger.
B. Too low or too high oil level in hydraulic
reservoir.
C. Same as D2.
D. Hydraulic pump not operating efficiently.
3. Excessively worn or damaged internal
winch parts.
Same as remedies for Trouble D1.
Thoroughly clean exterior and flush interior.
Fill/drain to proper level.
Same as remedies for Trouble D2.
Engine low on horsepower or R.P.M.
Tune/adjust prime mover.
Check suction line for damage.
Pump worn. Replace pump.
Disassemble winch to inspect/replace worn
parts.
F
Winch “chatters” while
raising rated load. 1. Same as D2.
2. Hydraulic oil flow to motor may be too low.
3. Controls being operated too quickly.
Same as remedies for Trouble D2.
Same as remedies for Trouble E2.
Conduct operator training as required.
G
The wire rope does not
spool smoothly on the
drum. 1. The winch may be mounted too close to
the main sheave, causing the fleet angle
to be more than 1-1/2 degrees.
2. The winch may not be mounted perpendi-
cular to an imaginary line between the
center of the cable drum and the first
sheave.
3. Could possibly be using the wrong lay
rope. There is a distinct advantage in
applying rope of the proper direction of lay.
When the load is slacked off, the several
coils on the drum will stay closer together
and maintain an even layer. If rope of
improper lay is used, the coils will spread
apart each time the load is removed.
Then, when winding is resumed, the rope
has a tendency to criss-cross and overlap
on the drum. The result is apt to be a flat-
tened and crushed rope.
4. The winch may have been overloaded,
causing permanent set in the wire rope.
Check mounting distance and fleet angle.
Reposition winch as required.
Refer to “Winch Installation”.
Consult wire rope manufacturer for recom-
mendation of wire rope that best suits your
application.
Replace wire rope and conduct operator/rig-
ger training as required.
