Load Chain
To determine if load chain should be continued in service, check gauge lengths and condition. Chain worn beyond the
maximum allowable gauge length (as shown in Chapter 6), nicked, gouged or twisted chain should be replaced before
returning the chain block to service.
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 with appropriate lubricant, taking into account the
application, temperature range, corrosion resistant properties required and other relevant conditions.
It is recommended that you lubricate load chain at least weekly, or more frequently than normal depending on severity of
service. Apply new lubricant over existing layer. Lubricate chain more frequently in a corrosive environment. Corrosion
resistant chain is available for Tiger chain blocks as an option on TCB models.
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
(crown/saddle) 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.
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 around the load sheave/wheel. Remove excess lubricant from the chain by wiping with a cloth.
When lubricating the chain, also check the chain for wear.
Clean dirty chains with acid free or water based solvent or a similar cleaning agent, to remove rust or abrasive dust build up.
Never heat the chain.
! WARNING
Make sure that no lubricant can penetrate into the brake enclosure. This may result in failure of the brake.
Replacing the load chain
The load chain must be replaced by a new chain of the same dimensions and quality in the event of visible damage or
deformations, or when the discarding status has been reached, at the latest.
A load chain to be discarded must only be replaced by an authorised competent person. Only fit load chains which have been
approved by the manufacturer. Non-compliance with this specification will render the legal warranty or guarantee void with
immediate effect.
If the chain links are not deformed, the chain can be replaced with the hoist in the suspended position as in the instructions
below. Alternatively, remove the hoist from the suspension point and work on a bench. If the chain is jammed in the lifting unit
the hoist must be removed and stripped.
Note: Replacement of a load chain must be documented!
