Lateral pressure stability

Multilayer spooling is a demanding issue for wire rope. Optimum lateral pressure stability is of extreme importance to achieve proper spooling behaviour. The leading crane manufacturers impose strict criteria in this regard, resulting in a standard requirement. For example the lateral deformation for a 16 mm rotation resistant hoisting rope must be in between 1.8 % (under 7.5 kN) and 16 % (under 120 kN load).
