Maintenance
10.1
General
All monitoring, servicing and maintenance operations are to ensure correct functioning of the equipment;
they must be effected with utmost care.
Only “qualified persons” may do this work.
Servicing and maintenance work must only be done when the hoist is not loaded.
Records must be kept of all test results and measures taken.
10.2
Monitoring
The monitoring and servicing intervals stated are valid for operation under normal conditions and single-shift
operation. In case of severe operating conditions (e.g. frequent operation with full load) or special
environmental conditions (e.g., heat, dust, etc.), the intervals must be shortened correspondingly
10.3
Replacing the load chain
CAUTION!
If there is any visible damage and when the conditions for replacement are reached (i.e. one or several dimensions in
the table have been reached, there is corrosion or elongation), the chain must be replaced.
When replacing the chain, also check the chain wheels.
Procedure:
Only insert new chains in an unloaded state and as the chains that are currently in the device – i.e. not
twisted.
Remove chain from its fastening at the end and attach a chain link which is open at the side.
A chain link which is open at the side, can
easily be produced by grinding out a small
piece. The opening must have the same
thickness as the chain link.
