WARNING!
If one or several of the dimensions fall below or exceed the dimensions in the table, or if cracks or corrosion
are found, the parts must be replaced with original spare parts.

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.
