If a chain appears to be faulty or worn, it must be
replaced ; the condition of the pulleys and the
telescopic mast alignment must be checked.
5.19.2 Chains lubrication.
Do not use grease to lubricate the lifting
chains.
Do not remove lubricant applied at the factory
from the chains. Do not use acid or detergent
to clean the lifting chains.
Lubrication of the lifting chains can be performed
manually with a 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 temperatures
according to the chart below :
A viscosity too low facilitates draining of the
lubricant by gravity. A viscosity too high
prevents the lubricant from reaching the
friction surfaces.
Lubricant must be applied :
- Longitudinally : in areas where joints are under
small load to facilitate penetration of the
lubricant.
- Transversely : between the plates to enable
the lubricant to reach the joint and between
the internal plates and the rollers (lubricant type
refer to § 8.1).s

5.19 Chain control and lubrication
The service life of a lifting chain depends on the work
platform operating conditions and on the environment
in which the machine is used or stored. Service life
is reduced if the chains are exposed to significant
temperature fluctuations, acid or corrosive products
or vapours, or abrasive dust.
Due to the high resistance level of their
components, chains can be weakened by
hydrogen.
5.19.1 Control of chain wear.
Inspect thorougly each chain in turn over its entire
length :
ç
Chains, chain yokes, clevis pins and split
pins must not be corroded.
ç
Plate must not be cracked.
ç
The plate clevis pins must not present
excessive play. The pins must not be
turned in their housing.

:
ç
Plates must not present a wear above 5%
of the total height (refer to chart below).
ç
Chain stretching cannot be superior to the
values indicated in the chart below :
