The present invention generally relates to the detection of the discard state of high-strength fiber ropes. The invention relates to a device for detecting the discard state of high-strength fiber ropes for various operating conditions, wherein a rope core of the fiber rope is sheathed with a rope sheath which is intended to wear more quickly than the rope core, comprising an optical detection device for detecting the rope surface and/or a load spectrum counter for detecting the load cycles to which the fiber rope is subjected, and on the other hand to a lifting gear such as a crane comprising such a device. According to the invention, there is provided a detection device for detecting the light absorption coefficient and/or the degree of reflection of the rope sheath and an adaptation device for adapting the algorithm, by means of which the discard state is determined, in dependence on the detected light absorption coefficient and/or the detected degree of reflection.
A device for determining a discard state of a high-strength fiber rope having a rope core comprising high-strength plastic fibers or strands and a rope sheath surrounding the rope core, comprising:
A method of using at least one high-strength fiber rope from a fiber rope set comprising a high-strength fiber ropes for various operating conditions in a hoisting device, wherein the high-strength fiber ropes comprise a first high-strength fiber rope having a first rope sheath with a first daylight absorption coefficient and a second high-strength fiber rope having a second rope sheath with a second daylight absorption coefficient, wherein the first daylight absorption coefficient is greater than the second daylight absorption coefficient, the method of comprising
