Table 7-1 Troubleshooting Guide
Improper braking may cause improper load lowering. The hoist utilizes dry friction discs; do not
apply oil to friction surfaces.
Symptom Cause Remedy
Load will not go down
Over tightened brake
The hoist left under load for a long period
Shock loaded during operation
Pull down hard (possibly with 2 people) on
the hand chain to loosen brake.
Brake rusted tight
Replace the rusty components and perform
hoist maintenance.
Load drifts or slips
when lowering
A foreign object between friction surfaces.
Remove the object and clean the surfaces.
Replace if the friction surface is scarred.
Brake slip caused by significant rust
Replace the rusty component and perform
hoist maintenance.
Mis-assembly of friction plates, i.e. friction
plates missing or at one side as shown.
Reassemble properly as shown and ensure
hoist functions properly before reuse.
Cracked friction plate caused by overload
Replace the friction plate and use the hoist
properly within rated capacity.
Friction plate wear caused by very frequent
and long term use.
Perform hoist maintenance.
