Entwicklung einer multifaktoriellen Messmethode zur Zustandsüberwachung von Faserseilen für Krane – Belastungen im Seil und Wahl des Leitermaterials

Abstract

A measuring system to determine the rope condition and time of discard of fiber ropes used on cranes is being developed. It consists of two electrical conductors integrated in the rope core and electronic components connected to them at regular intervals. These electronics have to be protected from the mechanical loads inside the rope. To design the necessary cylindrical and hollow protective covers, the compressive forces and their distribution are determined. Furthermore, various materials are tested for their suitability as electrical conductors in the rope, which mainly depends on their elastic elongation behavior and electrical resistance.
