• Cuts, notches, grooves, cracks: these defects, especially across the tensile
direction) can lead to sudden breaks!

• Excessive corrosion (e.g. pitting corrosion), material discolouration from
heat, burning of the outer surface coating, evidence of subsequent welding
• Missing and/or defective safety measures as well as evidence of the hook
being over-extended. The opening of the hook should not exceed 10 % of
the nominal dimension. A swing-out safety catch is proof that the hook has
been overloaded
Repairs: Subsequent repairs should only be done by qualified personnel with the necessary know-how and
experience.
When carrying out repairs, the chain as a whole must be repaired; individual pieces that are broken, obviously
deformed or stretched, heavily corroded, coated with non-removable debris (e.g. weld splatter), have deep cuts,
notches, grooves, cracks should be replaced immediately. Missing safety device such as safety latches, triggers,
pins as well as damaged, broken or missing springs should be replaced. Only use original pewag replacement parts
and accessories of the correct quality grade and nominal size. winner accessories can be used to repair Nicroman
lifting chains – new bolts, adapter sleeves and other safety elements are advisable.
Missing identification tags can be replaced with a new tag, but only after all the necessary tests have been
conducted and the load capacity is ascertainable using the markings on the individual parts and type.
Small cuts, notches and grooves can be eliminated (e.g. on large hooks or lifting chains) by carefully grinding or
filing. The newly repaired part should blend seamlessly into the adjoining material without there being a marked
difference in the cross-section. Through eliminating the damage, the material thickness must not have decreased by
more than 10 % – after the repairs, the chain should not fit into any of the "discard" categories.
Repairs that involve welding should only be carried out by pewag.
Documentation: The tests conducted by trained personnel, the outcomes as well as the maintenance logs should
be documented in a chain card index which should be kept for the whole of the product's working life.
These recordings and/or the manufacturer's declaration of compliance and conformity need to be shown to the
national trade control on demand.
Storing, Transportation
Lifting chains that are not being used should be stored on designated frames and not in a heap on the floor as that
would be the fastest way to damage them.
If unloaded lifting chains remain on the crane hook, then the end hook must be attached into the master link or,
if this is the case, the end links into the crane hook in order to reduce the risk chains sling legs swinging freely or
accidentally unhooking.
