Einflussgrößen auf die Lebensdauer von HM-HT-Faserseilen

Abstract

Steel wire ropes have established as transmission, connection and safety elements in intermittent conveyors such as cranes and elevators. This is justified due to their high breaking strength and operational reliability as well as their many years of experience. However, steel wire ropes have disadvantages such as high net mass, low bending elasticity and corrosion sensitivity. Increasing demands on energy-efficient and resource-efficient operation of technical systems are increasingly require new materials, technologies and processes. As a result, textile machine elements like HM-HT fibre ropes (high modulus - high tenacity) are also being considered. They offer an alternative to steel wire ropes due to their favorable breaking force-mass ratio. However, with the growing innovations new cases of damage also go hand in hand. It lacks on experience and long-term studies of textile tensile elements.
