If the hoist has been driven against the
lower final limit cam
If, due to heavy load and poor brake function, the hoist has been
driven against the final limit cam at the bottom landing so that
the power to the drive unit has been cut off, the hoist can be
cranked back manually to the normal landing level.
The motor brake should be checked by trained/authorized
personnel, before the hoist is put back into service.
WARNING!
Crushing hazard.
Always disconnect the power by means of the main
switch on the electrical panel before working on the
machinery.
Can cause severe personal injury.
Cranking
1. Release the lower brake (or both lower brakes on 3 motor
machinery) with one / two ratcheted tie down.
2. Apply a ratchet spanner with socket dia. 19 mm
on the hexagon shaft end of the brake motor.
3. Pull the ratchet spanner on the applied motor
brake in clockwise direction.
WARNING!
Violent stroke of the ratchet spanner.
Do not release ALL brakes at the same time
when the ratchet spanner is applied on the
shaft end of the brake motor.
Can cause severe personal injury.
Note. The hoist can be driven off the final limit cam by using the
equipment intended for drop test. See headline ”Drop test” in
chapter Service and Maintenance for instructions.
