Abstract
The present invention relates generally to lifting gear such as cranes which use high-strength fiber ropes instead of steel ropes. In this respect, the invention in particular relates to an apparatus for recognizing the discard state of a high-strength fiber rope in use at such lifting gear comprising a detection device for detecting at least one rope parameter as well as comprising an evaluation unit for evaluating the rope parameter and for providing a discard signal in dependence on the rope parameter evaluation. In accordance with the invention, the detection device of the apparatus for recognizing the discard state comprises a plurality of differently configured detection means for a magnetic, mechanical, optical and/or electronic detection of a plurality of different rope parameters which can be evaluated by the evaluation unit individually and/or in combination with one another for recognizing the discard state.
