Inspection and maintenance
•
This wire rope hoist is largely maintenance-free.
•
Components that are subject to wear (e.g. wire rope, brake) must be subjected to
regular tests.
–
This is also required by the accident prevention regulations.
•
Tests and maintenance must be performed by qualified personnel.
WARNING
Falling parts hazard.
➢
Cordon off and secure danger area before inspection and maintenance work.
WARNING
If work is necessary on live parts, a second person must be involved to stop hazardous
movements through emergency stopping
in case of an emergency or to actuate the main
isolation switch / disconnector to switch off the power.
NOTICE
Danger of material damage due to damage or wear
If tests or maintenance on the hoist show increased wear or damage, the hoist shall only
be put back into operation after the defects have been eliminated.
General information on inspection and maintenance
1.
Make sure a qualified person performs inspection and maintenance.
2.
Perform maintenance and repair work only when the hoist is unloaded.
3.
Before starting disconnect power and implement a Lockout/Tagout (LOTO) procedure
before servicing the equipment.
4.
Check that the hoist is de-energized.
5.
Perform periodic inspections including maintenance every 12 months, possibly earlier
if so prescribed by national regulations like ASME B30.16.
NOTE
: The specified inspection and maintenance intervals apply for normal
conditions of use.
If major components are replaced, further tests must be performed.
•
Replacing components of the overload safety device (sensor, electronic overload
device)
For load test of cut-off values of system, see separate Operating instructions / Service
manual
•
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
equipment, 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.).
•
If abrasive dusts are present (foundry, cement industry, glass manufacture or
processing, etc.) the maintenance intervals for the rope guide (cleaning, lubricating,
checking and if necessary replacing tension spring, etc.) must be reduced.
•
A general overhaul must be carried out after the useful lifetime has expired.
