Device for determining the replacement state of wear of a rope during use in lifting gear

摘要

The invention relates in general to lifting gear such as cranes, which use ropes such as high-strength fibre ropes. The invention relates in particular to a device for determining the replacement state of wear of a rope of this type during use in lifting gear of this type, said device comprising a detection system for detecting at least one rope utilization characteristic that influences the replacement state of wear and an evaluation unit for evaluating the rope utilization characteristic and for providing a replacement signal according to the evaluation of the rope utilization characteristic. According to the invention, the detection device has at least one detection means for detecting environmental influences on the rope, which influences can be evaluated by the evaluation device in order to identify the replacement state of wear.
