FIELD: instrumentation.
SUBSTANCE: devices are proposed to detect condition, when it is necessary to replace a rope (1) from high-strength fibres used in a lifting crane. The device comprises a device (2) for indication of a rope parameter, a unit of rope parameter evaluation and signal supply about unfitness depending on rope parameter evaluation. The device (2) for indication comprises facilities (2a) for magnetic, mechanical, optical and/or electronic detection of several parameters of the rope, evaluated by the specified unit of evaluation individually and/or in combination with each other for detection of unfitness condition. Also a crane is proposed, which is equipped with the above device.
EFFECT: invention provides for reliable accurate detection of unfitness condition by simple means of indication.
