Main performance of crane wire rope fatigue

The crane wire rope mainly suffers from bending fatigue and tensile, twisting, and vibration caused by vibration during use. The normal operation and operation of the crane have a great influence on the wire rope. Let me introduce it to you in detail.
The first type is bending fatigue. The steel wire rope is repeatedly flexed and flexed through the pulley or the reel. The bending of the wire rope is easy to cause fatigue of the wire rope, the toughness is reduced, and finally the broken wire is caused, and the fatigue broken wire appears to be the most severely bent of the strand. One side of the outer wire. Usually, the appearance of fatigue broken wire means that the wire rope is nearing the end of use.
The second type is the fatigue caused by stretching, twisting and vibration. At the beginning and the end of the starting and braking of the crane wire rope, the tensile force of the wire rope can cause metal fatigue before and after the load. In addition, the wire rope is often subject to distortion and vibration, which is also a cause of poor fatigue.
