Lifting chain how to properly tie heavy objects

Speaking of lifting chain, most of us think of 80-level lifting chain, which is also often used in the chain of lifting hoist, then the chain used in lifting operation can be tied and fixed? In essence, there is no obvious difference between the chain used for lifting and the chain used for binding, but the model of the chain will be different, so what do you need to pay attention to when the chain is used for binding operations?

First, when carrying out the binding operation, whether it is a black chain or a galvanized chain, it should be matched with the sling specifications and the volume of the binding, if the heavy volume of the binding is too large, we can choose some appropriate thickness of the chain for the binding operation, must not use a very thin chain to bind heavy weight and large volume objects, otherwise it is easy to be dangerous.

The second is the lifting work, the chain needs to keep smooth, and the binding work, the chain needs to keep tight, the chain with heavy loads will rise or fall, if the fixed is not strong then the heavy may slip out of the rigging, resulting in irreparable losses.
