Hook checks
Opening dimension l on the hooks is important. A hook with too
large a maximum dimension has been exposed to overloading or
overheating. It therefore does not have the necessary load capacity.
The hooks may also have been exposed to long-term wear (dimen-
sion K).
Hooks must be discarded and replaced if:
•
the maximum I value is exceeded (according to Table 2)
•
the minimum K value falls short (according to Table 2)
•
the hook is cracked, deformed or otherwise damaged.
Defective hooks must be replaced before using the lever hoist again!

Check measurement of chain
Inspect the chain over its whole length to detect any deformed
or otherwise damaged links. Make a check measurement of
suspect links. Measure the worn areas Also, every 300 mm
(normally), take check measurements of the internal length of 5
links (pitch dimension 5xP according to Table 3).

The chain must be discarded and replaced if:
•
cracks are detected on any link
•
any link is deformed or otherwise damaged
•
The minimum value of any link's diameter falls short
•
the maximum value of the pitch dimension is exceeded at any point
•
the chain is damaged by overheating or has been affected by weld splatter
Chains must not be repaired – they must be replaced by a new original chain. If it is desired to lengthen the chain, it must be replaced by a new
and longer chain.
Replacement of the chain shall be performed professionally by an authorized repairer and the chain must meet the requirements stated in the
standard EN 818-7 from the following manufacturers: Chaineries Limousines, Pewag, Thiele or Rud.
Repairs
The lever hoist must not be modified. Repairs must be carried out by specialists. Damaged parts must only be replaced with original Powertex
spare parts. Order them through your dealer.
