Special lifting chains winner fire for use in hot-dip galvanisation
Purpose: Mounting and lifting/transporting loads to be galvanized. In doing so, the chains go through a repetitive
work cycle „stripping" and "galvanising". The chains can be used in a 15 % hydrochloric acid pickling bath and also
in a zinc bath. Light material removal through the acid and the zinc is normal.
Temperature application range: -40 °C to 30 °C (pickling bath) or 475 °C (zinc bath).

The coefficient for the static test = 2 x load capacity respective of the chain segment. Attention: the load capacity
and in turn the test force for the static test of the individual chain segments (e.g. an individual chain strand of a
multi-leg lifting chain) differs from the total load capacity.
Reduction factors
The maximum load capacity of the chain sling arises from multiplying the load capacity on the tag with the
corresponding reduction factor according to the table as well as the accompanying factors in the table on page 28.

Misapplication: Not to be used with chemicals or other higher concentrated acids not stated in this instruction
manual.
Testing: The chains should be visually inspected after they have been thoroughly cleaned (stripped). Do not test
above the maximum load capacity! This would increase the risk of stress corrosion cracking.
