TROUBLE
F
Winch "chatters" while raising rated
load.
G
The wire rope does not spool smooth-
ly on the drum.
PROBABLE CAUSE
1. Same as D2.
2. Hydraulic oil flow to motor may be
too low.
3. Controls being operated too
quickly.
1. The winch may be mounted too
close to the main sheave, caus-
ing the fleet angle to be more
than 1½ degrees.
2. The winch may not be mounted
perpendicular 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 flattened
and crushed rope.
4. The winch may have been over-
loaded, causing permanent set in
the wire rope.
