8. Technical Information for the Versions
Fundamentals for the following information are our internally gathered
experience, based on EG-Richtlinie 2014/34/EU ATEX guidelines. For chain
hoists in areas 1 and 21, the technical construction documents are registered at
the stated offi ce (no.0123).
In the “HIGH” version, load chains are used with NIROSTA special load
chain fabrication steel, which causes a reduction in the load-bearing
capacity of the series chain hoists.
The table below gives you the varying load-bearing capacities in the
“HIGH” version compared to the “BASIC” and “MEDIUM” versions.
The hoists themselves are in the “HIGH” version, but already indicated
with lower load-bearing capacity on their nameplates.
