CHECKS ON LIFTING CHAINS
1) Chain noise
A grinding metal noise will be heard if the chains are not fully lubricated. This
causes metal-metal friction between the joints of the chain, which can lead
to seizing-slipping effect, causing the work platform to move unevenly.
2) Surface rust
Plates with rusty surfaces are easily recognisable by the typical brown
colour. Rust can lead to chain fatigue failures.
3) Rust on joints
Corroded connection points are recognisable by their red-brown colour. This
phenomenon may arise from lack of lubrication or use of grease and oil
unsuitable for penetrating the joints.
4) Stiff joints
Any joint that is not in a straight position when leaving the return pulley, can
no longer be used. This phenomenon may be caused by corrosion or cold
micro welding.
5) Turned pins
This is the consequence of incorrect lubrication and the aforementioned
phenomenon of stiffened joints. This phenomenon is easily recognised by
the difference in the pin clinching positions compared to factory standard.
6) Pins coming out of their housings
A direct consequence of the stiff joints of turned pins.
7) Wear
It is important to assess whether the connection plates are very worn.
