Abstract
The present invention generally relates to lifting gears such as cranes which use ropes such as high-strength fiber ropes. The invention in particular relates to a device for determining the discard state of such rope in use on such lifting gears, comprising a detection device for detecting at least one rope utilization parameter influencing the discard state and an evaluation unit for evaluating the rope utilization parameter and for providing a discard signal in dependence on the rope utilization parameter evaluation. According to the invention the detection unit has at least one detecting means for detecting environmental influences on the rope, which can be evaluated by evaluation devices to recognize the discard state.
