Tighten the nut on the anchor
of the chain that is too slack or
loosen the nut of the anchor of
the chain that is too tight,
ensuring the final alignment of
the mast sections is kept.
6- Check the presence and
correct tightening of the locknut
on each chain anchor.
7.8 Verification and lubrication of
the lifting chains
Service life of a lifting chains depends from the
operating conditions of the platform and from the
environment in which the machine is stored or used.
Service life is reduced if the chains are exposed to
important temperature variations, acid or corrosive
products or vapours or abrasive dust.
Because of the high resistance level of their
components, chains can be weakened by
hydrogen.
7.8.1 Verification of chain wear
Inspect thoroughly each chain over its entire length :
ç
Chains, anchors, clevis pins and split pins
should not be corroded.
ç
Plates should not be cracked.
ç
The plate clevis pins should not present
excessive play. Pins should not have turned
in their housing.
(1)
:
ç
Plates should not be worn above 5% of their
total height (See chart below).
ç
Chain should not have stretched the values
indicated in the chart below :
If a chain appears faulty or worn, it must be replaced;
the condition of the pulleys and the telescopic mast
alignment must be checked.
7.8.2 Chain lubrication.
Do not use grease to lubricate the lifting
chains.
Do not remove the lubricant from the chains.
Do not use acid or detergent to clean the
lifting chains.
Chains can be lubricated manually with a paint brush
or by spraying.
Chain lubrication intervals must be established with
care, depending on the environment in which the work
platform is operated or stored (dusty or agressive
environment).
The lubricant must be adapted to the machine's
operating conditions.
In general, a non detergent mineral oil is sufficient.
Its viscosity must be adapted to the temperature
according to the chart below :
