CAUTION!

 

When the dimension of hook opening width is deformed more than 10% or when the dimension of the hook 
bottom thickness is fallen short of by 5% due to wear, the hook must be replaced.

12.1 

Load chain 

Wear at the links is mainly due to insufficient maintenance of the chain. 

To ensure optimal lubrication of the links, the chain must be lubricated at regular intervals, depending on 
usage. 

  Lubricate the chain with oil that creeps. 

  Always lubricate the chain when it is not under load so that the oil can wet the links affected by wear. It is 

not sufficient to lubricate the chain from the outside, as this will not ensure the formation of a lubricating 
film within the links. The adjacent link points must always be lubricated to prevent excessive wear.  

  If the same lifting operations are carried out constantly, the switching area from a lifting to a lowering 

movement must be given special attention. 

  Thoroughly effected lubrication of the chain will prolong the life of the chain by approx. 20 times, 

compared to dry run with unlubricated chain. 

  Wash dirty chain with petroleum or a similar cleaner, under no circumstances heat the chain. 

  If there are environmental influences that foster wear, such as sand, a dry lubricant should be used, e.g. 

graphite powder. 

  When lubricating the chain’s condition of wear should be checked.
