12.4.3 Measuring the wear on the chain
This should be done by measuring the dimensions, at several points of the chain, of one link (d) and
(t), and over 11 links (11 t).
Maximum wear allowed :
Minimum link thickness allowed (d) :
4.30 mm
Maximum pitch allowed (t) :
13.10 mm
Maximum length allowed (11 t) :
140.25 mm
)
If these limits are exceeded
, the chain must be replaced immediately
. In this case, the wear
on the guide chain and chain sprocket should also be checked and they should be replaced if
necessary.
)
If a single link is defective in any way whatsoever,
the chain must be replaced
,
A repetitive stop and start at the same point of the chain will create a more important
wear on the 2-3 links which are in the chain sprocket
Never twist the lifting chains (turning around of the hook block)
