4.3 Technical specifications ATEX
Worm gear screw jack for use in spaces with explosion hazards are designed based on the
environmental influences (ATEX checklist) that have been given to us. The technical specifications and
ATEX terms and conditions specified in the order confirmation must be adhered to. The manufacturer of the
total system needs to evaluate the suitability according to the identification.
The declaration of conformity, in accordance with guideline 2014/34/EC, is rendered void if the
technical data and ATEX conditions are not adhered to
