Research on the Comprehensive Testing of Drawbacks in Wire Ropes

The method and principle of testing steel wire ropes are proposed. According to the ferromagnetic characterstic of the steel wire ropes, the drawback of the steel wire ropes is detected by the magnetic method, the magnetic flux leakage method is adopted to test the broken wires of the wire ropes, the wear of the wire ropes is detected by magnetic bridge circuit method and the Hall displacement sensor is applied to measuring the diameter of the wire ropes. All these methods are integrated into one detector. By designing corresponding the electronic circuit and signal processing software, the comprehensive drawback is inspected.
