The lifting chain is widely used in shipbuilding, equipment manufacturing, storage and transportation of steel structures and other industries, with a wide range of applications, high safety factor, small elastic deformation, not easy to twist and deform, convenient storage, safety and reliability, etc.
In hoisting operation, it has the same function as steel wire rope, especially in small and medium tonnage hoisting operation, which is more durable and convenient than steel wire rope. During binding and lifting, the steel wire rope is easy to coil and forms a dead bend when the curvature radius is small, which is very inconvenient to use. In addition, when the steel wire rope encounters sharp edges and acute angles, it is easy to break, which is a prominent hidden danger, but the chain does not have this problem in use.
From the perspective of economic benefits, the price of lifting chains and wire ropes of the same tonnage and form is about 10% higher than that of wire ropes, but under normal use, the service life of lifting chains is three times that of wire rope rigging. To sum up, the economy of chain rigging is self-evident.
