2. The strong magnetic detection mostly requires that the detection sensor is close to the surface of the steel wire rope as much as possible and is limited by the detection speed. When the steel wire rope shakes or the running speed changes greatly, the sensor cannot detect a real damage signal, and the reliability and the stability of a detection result are poor.
