Checking of the outreach extension and retraction chains
6.4.13.1
Lengthening of the chains
Attention
: The chain must be replaced when the elongation reaches 3% of the original length.
To check the elongation it is necessary to measure the length of approximately 10 links of the
chain (record the value) before the machine is put back into service.
Periodically (according to the general table in the previous chapters) the 10 links must be
measured by configuring the machine in the same condition it was in when it was originally
measured.
If the measured value is greater than 3% of the original value, the chain must be replaced.
Also perform visual checks on the condition of the links in the chain.
Dents and corrosion are conditions that require more thorough checks by an authorised
workshop.
L = 10 links + 3%
L = 10 meshes
