Stretching
The amount of stretch on a lifting chain is measured on the part of the chain
that runs over the chain roller. The amount of stretch may, at the most, be 2%
on the most worn section of the chain.
The measurement is best made over 300-1000 mm of chain.
The nominal and maximum permitted chain lengths for lift chains are stated in
the table below.
Wear to the bolts and around the holes on the discs is one reason why the
chain stretches. The chain must be replaced if is stretched more than 2%.
Damage
The chain should be replaced if damaged in any way.
