7.1 Faults during lifting platform operation
Fault
No motor operation.
Motor operation but lifting
platform not raised.
Support arm locking not working
Lifting platform not lowered.
Noise during lifting or lowering.
Lifting platform tilts on raising
or lowering.
No cut-out by switch rod at
overhead beam.
7.2 Emergency lowering in the event of
power failure
i
No power is required for lowering the lifting
platform. The lowering valve is actuated
mechanically by way of the control lever.
This means that the lifting platform can be lowered
even in the event of power failure, simply by pressing
down the control lever (u).
Emergency lowering
The method described above will not work if the
locking pawls are not released. In this case the lifting
carriages must be raised slightly to relieve the load
on the locking pawls. The lifting platform can then be
lowered by way of the control lever. Always heed the
following hazard warning when doing so:
