This document deals with all significant hazards, hazardous situations and events relevant to haul-offs
for cable, cable core, profiles and pipes for processing plastic and rubber, when they are used as intended
and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
The hazards have been identified taking into account all phases of the machine life cycle according to
EN ISO 12100:2010, 5.4.
The following kinds of haul-offs are covered:
— caterpillar haul-offs;
— belt haul-offs;
— capstan haul-offs;
