DANGER
BECAUSE OF THE HIGH RESISTANCE
OF THEIR COMPONENTS, CHAINS
CAN BE WEAKENED BY HYDROGEN.
YOU
SHOULD
STAY
CLEAR
OF
OXYDATING
AND
CORROSIVE
ENVIRONMENTS.
ACID
ENVIRONMENTS
MUST
BE
AVOIDED. TAKE GREAT CARE IN CASE
OF
DEGREASING.
ALL
SURFACE
TREATMENT
ON
A
CHAIN,
IN
PARTICULAR
ELECTROLYTE
TREATMENT SHOULD BE BANNED.
1.2.3 LIFTING CHAINS
LIFTING CHAIN MAINTENANCE
Regularly check:
- The geometry of the assembly, in particular the alignment of the anchors with the pulleys and
the wear of the pulley
- The condition of the chain, in particular to detect possible friction indicating an incorrect
geometry of the assembly or contacts with structure parts.
- Wear of the chain links either by measuring the chain length (measuring instrument or ruler),
either by appreciation or measurement of its deflection or of the shifting of the tensioning
device.
- Wear of the plates of the lifting leaf chain.
- Wear of the pulley bushes.
Find the cause of the malfunction and rectify. Replace the pulley or the chain if too worn (over 2%
of the chain length and over 5% of the height of the plates). It is advised to replace the assembly
chain + pulley.
LUBRICATION
The lubrication’s role is to:
- Keep a fluid between the friction surfaces
(pin/bush, pin/plate, bush/roller, plate/plate…)
to reduce their wear and prevent seizing.
- Protect the chain against corrosion.
- Reduce the noise by getting between the
surfaces subjected to shocks.
- Release the heat from the energy released in
friction..
