Standardized operation of transmission and load-bearing is required for lifting chains to avoid chain twisting and jamming. When lifting chains are used for transmission or load-bearing and need to operate with sprockets, chain twisting is a common cause of damage. If the chain is not inspected for twists before use or misaligned during installation, the twisted links will fail to smoothly engage with the sprocket tooth grooves during operation. This not only causes problems such as chain jamming and abnormal noise but also leads to severe frictional wear between the chain links and the sprocket.
Meanwhile, the chain itself may experience local stretching and deformation due to uneven force distribution. Therefore, before the installation and use of the chain, carefully inspect whether the links are straight to ensure there is no twisting or knotting; if the chain is found to be misaligned or stuck during operation, immediately shut down the equipment for inspection. Check if the sprocket is worn or the chain is misaligned, and resume operation only after the problem is resolved.
