At present, there are three kinds of sling, wire rope and chain sling, which are most widely used. If we distinguish from the material, it is mainly the lifting belt and the metal sling. The lifting belt is mainly made of synthetic fiber, while the wire rope and chain are made of metal. So what kind of lifting operation are these two kinds of slings used respectively? Chenghua Manufacturing makes a simple popular science for you.
It is well known that the strength of synthetic fiber materials is far less than that of metal materials, so it seems that the wire rope and lifting chain can be competent for all lifting operations, and the lifting belt is in the status of dispensable. In fact, this is not the case. Many lifting operations not only focus on the strength of the sling, but also on the protection of the sling to the lifting target.
There are a lot of there is no fixed points of the hoisting, the wind fan blade assembly is so, for example, and according to the lifting operation, such we need to take the way of bundling hoisting, and the binding will need to use to lifting belt, lifting for lifting the quality of a material soft, in the process of bundling lifting blades will not cause scratch and indentation, in contrast, wire rope and chain rigging, There is no way to operate under high load without causing significant indentation to the fan blade. This is the advantage of lifting belts, and such lifting operations are not uncommon. When faced with some aesthetic requirements for surface is not very high, and has the wind lifting objects of edges and corners, the advantage of metal sling will play out, because of sharp edges and corners on hoisting belt may be cut, so as to face great risks, in contrast, metal sling, without having to worry about this problem, this is the advantage of metal sling. There are also many such lifting operations.
This is the different lifting operations of lifting belt and metal slings. Both kinds of slings have their own uses, and neither of them will be completely replaced.
