Analysis of the reasons for crane hook rotation

Thread Content

The rotation of the crane hook is a common hazard in crane lifting operations. When the hook rotates, it can become entangled with the steel wire rope, causing the load being lifted to rotate as well, which hinders the smooth progress of the lifting process and can even lead to serious accidents. Therefore, it is very important to correctly understand the reasons for hook rotation, as well as how to prevent it and deal with it afterward. There are internal and external factors that cause the rotation of a crane hook. Factors such as lifting height, length of the wire rope, weight of the load, dimensions of the hook assembly, size of the pulleys, as well as human and wind power, can all cause the hook to rotate. To prevent the dangerous behavior of hook rotation, it is necessary to take proper measures to improve the stability of the hook. For example, increasing the number of strands in the wire rope, using pulleys with larger diameters, avoiding simultaneous use of the lifting hook and rotating motion, and opting for wire ropes that do not rotate, etc. Furthermore, when the hook rotates during crane lifting, if possible, it should be safely placed on the ground and aligned before continuing work; otherwise, another crane will have to be used to lift the cage in order to align the hook.
