Definitions

  • the present invention relates generally to hoists such as cranes that use ropes such as high strength fiber ropes.
  • the invention relates in particular to a device for monitoring operating data and / or determining the readiness for discarding of such a rope when used on such hoists, with a detection device for recording at least one rope usage parameter influencing the discardability and a data memory for storing the recorded rope use parameter and / or one operating parameter derived therefrom, which characterizes the remaining service life and / or maturity of the rope.
  • a rope is known in which a rope force transducer is woven in the form of a piezoelectric element, voltage values of the piezo element being stored in a transponder unit connected to the piezo element, which is also provided in the rope, so that they can be read out.
  • a disadvantageous property of such high-strength fiber ropes is their breaking behavior or their failure without clear, longer advance notice. While the wear and tear of steel ropes is clearly evident and a long-term failure is foreseen, for example due to the breakage of individual steel wires and a corresponding splicing that is simply noticed, high-strength fiber ropes hardly show any signs of excessive wear that would be easily perceptible to the eye and would show up clearly over a period of time before the actual failure. In this respect, intelligent monitoring measures are required in order to detect the maturity of high-strength fiber ropes in good time.
  • a rope is also known in which an RFID chip is embedded.
  • Certain manufacturer data such as batch, raw materials used, stranding speed or stranding date are to be stored in the said RFID chip during manufacture, so that conclusions can be drawn about the manufacturing conditions in the event of a later break in the rope or general problems with the rope .
  • the effects on the lifespan of a rope that differ greatly which can lead to a wide spread of the actual lifespan, can hardly be predicted from the rope's data stored by the manufacturer, however, the actual discardability, which is particularly the case with fiber ropes an unpredictable failure or vice versa when determining a worst case scenario can lead to the loss of a larger part of the usual lifespan.
