MAINTENANCE
Make frequent and careful inspections of the puller. Make
sure puller and wire rope are sufficiently oiled, and that
they are free of any sand, dirt, dust or other obstruction or
abnormality.
Make sure hooks are not deformed and that the puller body
has not been warped or damaged.
Use care to prevent the wire rope from kinking. If the rope
is left shaped like a basket or is kinked many turns at a
single point, its strength is greatly diminished and may
result in failure.
Replace the wire rope immediately if:
• The thickness of the rope becomes less than
half of the original value due to abrasion.
• The rope exhibits basket-like shapes, kinks,
or any abnormal deformation.
• The rope is given an exceptionally heavy shock during
operation; this can fatigue the rope even if the load is
within puller capacity.
• The entire rope is napped due to many small cuts.
• The eye section (thimble) of the wire rope becomes
elliptical in shape.
• The clamp is deformed.
Trouble
Probable Cause
Remedy
Insufficient lubrication.
Oil the puller and wire rope.
Wire rope will not move in
either direction.
Puller is dirty.
Disassemble and clean out dust, dirt or other
foreign matter. Oil the puller after reassembly.
Clamp lever is not in proper
position.
Release clamp lever from notch,
and allow it to return to engaged position.
Clamp lever is not in proper
position.
Release clamp lever from notch,
and allow it to return to engaged position.
Wire rope will not advance
during normal operation, or
advances with great difficulty.
Pawls are not lubricated.
Oil the pawl linkages properly;
the pawls must engage the wire rope.
Load is beyond puller capacity.
Decrease load.
There is an obstruction within the
wire rope’s path.
Remove the wire rope; clean and oil the puller
and the wire rope.
The reverse lever is engaging the
wire rope.
Check the position of the reverse lever.
Correct as needed.
Clamp lever will not engage
the wire rope properly.
Spring on clamp lever has
become stretched.
Replace spring.
