The Guanhang lifting chain is an essential transmission device in lifting equipment such as electric chain hoists, stage electric hoists, and chain hoists. As an important retrieval device, its smoothness, load-bearing performance, and crack resistance play a crucial role in improving the operational efficiency of lifting machinery. However, once the chain experiences twisting, deformation, or other faults, it will bring serious harm.

For example, it can cause the heavy object being lifted to suddenly fall off during a violent pause, increase the workload of the crane operator, and in severe cases, cause damage to the casing of the lifting machinery equipment. Therefore, when the chain is twisted and deformed, we should actively take measures to deal with it.

The handling measures can be determined based on the degree of twisting and deformation of the lifting chain. If the distortion exceeds 10 °, it must be scrapped and the original specification and model of the chain must be reinstalled before it can continue to be used. If it is only a slight deformation that does not affect the normal operation of the lifting machinery equipment, special tools can be used for correction.

However, no matter what measures are taken, they will have some impact on the customer's lifting operations. Therefore, when using Guanhang lifting chains for lifting operations, overloading should be strictly prohibited to avoid twisting and deformation.
