Inspection and maintenance
This section deals with operational reliability, availability, and maintaining the value of
your chain hoist.
Although this chain hoist is practically maintenance-free, the components subject to wear
(e.g. chain, brake) must be inspected regularly. This is required by the accident preven-
tion regulations.
Inspection and maintenance must be carried out by qualified persons, see chapter 1.6
WARNING
Danger of falling parts
➢
Cordon off and secure danger area before performing inspection and maintenance
work.
NOTICE
General information on inspection and maintenance
•
Maintenance and repair work may only be carried out when the hoist is unloaded.
•
Before starting, switch off and lock main isolator.
•
Check that the hoist is de-energised.
•
Observe the requirements of the accident prevention regulations.
•
Periodic tests including maintenance every 12 months, possibly earlier if so pre-
scribed by national regulations, are to be performed by a certified fitter.
•
The specified inspection and maintenance intervals apply for normal conditions of
use.
If major components are replaced, further tests must be performed.
•
Replacement of electrical equipment and renewal of electric leads and connections
Insulation resistance test and testing the continuity of the PE system
•
Correct phase connection
The hoist's electrical equipment must be checked regularly. Damage to electrical equip-
ment, loose terminals, damaged cables and worn switchgear contacts must be remedied
immediately.
The inspection and maintenance intervals must be adapted accordingly if one or more
the following conditions apply:
•
If after evaluating the actual use it can be seen that the theoretical useful life of the
hoist will be less than 10 years.
•
In the case of operation in more than one shift or heavy duty.
•
In the case of adverse conditions (dirt, solvents, temperature, etc.).
A general overhaul must be carried out after the useful lifetime has expired.
Lubricants and lubrication points, see page 53.
