Nominal dimensions and wear limits are shown in table 2. If one of the limit values is reached,
the load chain must be replaced.

Maintenance of the load chain
In most cases, chain wear in the link points is caused by insufficient care of the chain. In order
to ensure optimal lubrication of the link contact points, lubricate the chain at regular intervals
adapted to the application with creep-type lubricant (e.g. gear oil). A dry film lubricant, e.g.
PTFE spray, should be used in environments where abrasives like sand, etc., occur. The
service life of the load chain can be increased by careful lubrication to 20 - 30 times compared
with a chain that is not serviced.
• When lubricating the chain, make sure the chain is in no-load condition so that the oil can
reach the contact points of the chain links which are subject to wear. Chain link parts
contacting each other must always be coated with lubricant, otherwise increased wear on the
chain results.
• It is not sufficient to lubricate the chains on the outside as this does not ensure that a
lubricant film can build up in the contact points.
• With a constant lifting path of the chain, the change-over area from lifting to lowering
movement must be checked in particular.
• Make sure that the load chain is lubricated over its entire length, also including the part of the
chain in the housing of the hoist.
• Clean dirty chains with petroleum or a similar cleaning agent, never heat the chain.
• When lubricating the chain, also check the chain for wear.
ATTENTION: It must be ensured that no lubricant can penetrate into the brake
enclosure. This may result in failure of the brake.
