Beschreibung
Zusammenfassung:	The invention relates in general to lifting gear such as cranes, which use high-strength fibre ropes instead of steel cables. The invention relates in particular to a device for detecting the replacement state of wear of a high-strength fibre rope during use in such lifting gear, comprising a detection system for detecting at least one rope characteristic and an evaluation unit for evaluating the rope characteristic and for providing a replacement signal depending on the rope characteristic evaluation. According to the invention, the detection system comprises flexural-rigidity determination means for determining the flexural rigidity of the rope and the evaluation unit provides the replacement signal according to the flexural rigidity of the rope that has been determined.
