Maintenance
•
Trained specialists must carry out all maintenance work.
•
The Table 8 lists the parts and functions to be tested and the necessary maintenance work. Defects
must be rectified immediately by a trained specialist. Defects have to be reported immediately to the
owner. The owner is responsible to get defects remedied by a trained specialist.
•
Maintenance work may only be carried out if the electric chain hoist is not loaded and the main
switch is switched off so that the power supply is disconnected.
•
In case of very harsh operating conditions, e.g. multi-shift operation, high number of switching
actuation, poor environmental conditions, the periods between maintenance works must be
shortened.
Checking for wear
•
Check suspension hook and load hook for deformation (measure punch spacing) and rusting, cracks
and the general condition.
•
The chain sprocket in the hook block must be replaced if the running surface is worn by about 1 mm.
•
Check the load chain according to chapter 7.10.2
•
Replace all rubber buffers if worn!
7.1
Maintenance and checks
Note chapter 1 !
The following time periods are estimated, they may have to be shortened due to hard operating conditions (two or
three shifts, high percentage of work with nominal load, dusty or high temperature environment) this maintenance
work has to be done more frequently.
Check
daily
every 3
months
yearly
