3.2 Care and maintenance
General:
Care and maintenance tasks are preventive measures designed to preserve the full functionality of electric chain hoists. Non-compliance
with care and maintenance routines can result in limited use and damage to electric chain hoists.
Care and maintenance should be carried out in accordance with the instruction manual at predefined time intervals (table 3-1 and 3-2).
During care and maintenance work, general accident prevention directions, special safety directions (chapter 0.3) as well as hazard pro-
tection instructions (chapter 0.4) should be followed.
Care and maintenance work should be performed only on electric chain hoists with no loads. The main switch must be off. The
hook fittings must lie on the ground or on the maintenance platform.
Care work encompasses visual checks and cleaning routines. Maintenance work includes additional functional checks. During the functio-
nal checks, all fixing elements and cable clamps must be checked for tightness. Cables must be inspected for dirt, discolouration and arc
spots.
Used operating materials (oil, grease, etc.) should be safely collected and disposed of in an environmentally friendly manner.
Care and maintenance intervals are defined as follows:
d (daily), 3 m (quarterly), 12 m (annually)
The predefined care and maintenance intervals should be reduced when the loading of the electric chain hoist is exceptionally large or
when frequently operated in adverse conditions (e.g. dust, heat, humidity, steam, etc.).
