36- Main lift chain system – 7120
36.1 General
Applies to all machines with a mast.
36.2 Checking the chain setting
The lift chains must be adjusted at regular periods due to stretching,
see below. The chain setting is checked during servicing as set out in
the maintenance schedule.
Any adjustment is made with the chain mounting bolts.
Adjust the fork height according to C code 7100, 7420, 7700 and 7800
as applicable.
36.3 Chain inspection
The chains are exposed to two types of wear, outline wear and stretch-
ing. Wear to the bolts and disc holes is caused by stretching. The
chains are also affected by the environment they are used in.
36.3.1 Noise
If lubrication has been insufficient there will be metallic friction on the
chain and this will result in noise.
The chain should be replaced.
36.3.2 Surface rust
Surface rust is easy to recognize as the chain will be reddish brown.
Deep-seated rust has generally started and the chain has impaired
strength.
The chain should be replaced
36.3.3 Rusty links
Fretting corrosion results in a reddish brown powder being visible by
the outer discs. It can also appear as if the chain is bleeding when lubri-
cated.
The chain should be replaced.
