The chain rigging is a rigging made of metal chain link. According to its form, there are mainly two kinds of welding and assembling. The outstanding features are wear resistance, high temperature resistance, low ductility, and no elongation after force. It has long service life and easy to bend, and is suitable for large-scale and frequently used occasions. Flexible multi limbs and multiple combinations can improve work efficiency, reduce cost, and so on.
