4. Service and maintenance

Operating failures in electric chain hoists affecting the safe operation of
the device should be remedied immediately.

4.1. General regulations for service and maintenance work

CAUTION!
Maintenance and work on the electric chain hoist may only be carried
out by qualified and trained personnel.
CAUTION!
If the operator performs maintenance work on an electric chain hoist
on his own account, the type of maintenance performed together with
the date carried out must be entered in the log book.
Alterations to, as well as modifications and supplements to electric chain
hoists which may affect safety must be authorized by the manufacturer
in advance. Structural alterations to chain hoists not authorized by the
manufacturer exempt the manufacturer from liability in case of damage.

General:
Service and maintenance are preventive measures designed to preserve
the full functionality of electric chain hoists. Non-compliance with service
and maintenance routines can result in reduction in the useful function of
and/ or damage to electric chain hoists.
Service and maintenance work should be carried out at the predefined
time intervals, in accordance with the instruction manual (Table 4-1 –
Care overview and Table 4-2 – Service overview).
During service and maintenance work, general accident prevention
directions, special safety directions (chapter 1.3) as well as hazard
protection instructions (chapter 1.4) should be followed.
DANGER!
Service and maintenance work should only be performed on unloaded
electric chain hoists. The main switch must be off. The lower sheave
or hook fittings must be lying on the floor or a maintenance platform.
Maintenance work encompasses visual checks and cleaning routines.
Service work includes additional functional checks. During the functional
checks, all securing elements and cable clamps must be checked for
secure seating.
Cables must be inspected for dirt, discoloration and arc spots.
CAUTION!
Used operating materials (oil, lubricants, etc.) should be safely
collected and disposed of in an environmentally friendly manner.
Service and maintenance intervals are defined as follows:
t: daily
3 M: quarterly
12 M: annually
The predefined service and maintenance intervals should be reduced
when the loading of the electric chain hoist is exceptionally large and
when frequently operated in adverse conditions (dust, heat, humidity,
steam, etc.).
