Chain rigging is a type of rigging that is connected by metal chain links. According to its form, there are mainly two types: welding and assembly. According to its structure, it is made of high-quality alloy steel, which is characterized by wear resistance, high temperature resistance, low ductility, and no elongation after being subjected to force. It has a long service life, is easy to bend, and is suitable for large-scale and frequent use. Flexible multi limbs and various combinations can improve work efficiency and reduce costs.
