Generally speaking, the sling equipment includes both sling and rigging, so what are the specific differences between sling and rigging? First of all, we can see from the definition, sling, which refers to the rigidly lifting device for lifting the heavy lifting operation. That is to say that the articles can be directly suspended, mainly: hook, grab, clamp, sucker and special sling, and so on. And the rigging is used to tie the goods. It is usually composed of high strength flexible parts (wire rope, hoisting ring chain, artificial fiber belt, etc.) with end ring, hook, unloading buckle and so on. The limit working load of the general hanger refers to the maximum mass (weight) of the goods under the vertical suspension under the normal use of the single sling; the maximum safety load of the rigging: except for the vertical suspension, there is a angle between the hoisting point and the articles, which makes the force of the sling change and in a specific hanging way. The maximum allowable load is called its maximum safe working load. So you can understand that the word “hoisting rigging” can not be simply understood as a product, nor can it be realized that all the hoisting devices have the same function and need to be understood.
