EXTREME LOADS BY MULTI SHEAVES FRICTION DRIVES

Sometimes unexpected overloads start up in multi-sheaves cable systems by synchrodrive. These overloads can not be foreseen and could cause the breakage of the rope(s). The correct measuring of tensile force in wire rope is necessary to prevent the breakage. By right and correct measuring the reasons of the breakage could be defined. In this publication the tensile force is measured by micro-modeling and a spring is used instead of wire rope. According to the theoretical analysis and the experiences the wear and the slide have the greatest influences to the overloads. The main aim of this publication is to show shortly the influences of the wears and the slides.
