Checking the load chain
CAUTION!
The load chain must be tested over its entire length!
The measure of the load chain must be carried out especially in the areas which are subject to the highest
wear. Through the lifting movement, these are the contact points of the chain with sprocket wheel and
deflection pulleys.
acc. DIN 685-part 5
L11 = pitch increase over 11 chain links
L1 = pitch increase over 1 chain link

WARNING!
When the dimensions listed in the table are reached due to wear or deformation, the chain must be
replaced!
DANGER!
In case of corrosion and/or wear of the surface coating, the chains must be exchanged by original
chains!
