What are the synthetic fiber lifting belts?
There are many names for slings, such as synthetic fiber slings, round slings, flexible slings, flat slings, white slings, and colored slings Belts, etc., how to distinguish such a wide variety of lifting belts? In fact, they are all made of synthetic fiber, so we can call all lifting belts synthetic fiber lifting belts.
1. Divide according to shape
Synthetic fiber slings are divided according to their shapes, and they are divided into round slings and flat slings. The shape of the round sling is It is round and relatively thick. The flat lifting belt is flat in shape and has a certain thickness. At the same time, there is one thing to note. The round lifting belt is also called a flexible lifting belt.
2. Divide according to color
If the color of synthetic fiber lifting belts is divided, we generally divide it into white lifting belts and colored lifting belts. This kind of The classification is mainly based on different materials. Most white slings are made of polypropylene, and most colored slings are made of polyester.
Through these divisions we can combine them to call them, including white flat slings, colored flat Lifting straps, colored flexible lifting straps, etc. This is how to distinguish lifting straps.
Why are synthetic fiber slings so strong?
Since 1955, the world’s first synthetic fiber flat sling was successfully used in the United States After being used in the field of industrial hoisting, the hoisting industry has entered a new era.
So where does its strength come from? Synthetic fiber is a synthetic polymer compound. There is a binding force between molecules. This bonding force is like hands pulling each other tightly. If the molecules of a certain polymer compound are arranged neatly, their pulling forces will be in inconsistent directions, forming a huge binding force and high strength. On the contrary, if the internal molecules are not arranged neatly and the direction of the pulling force is inconsistent, its strength will also be low.
In addition to the advantage of strength, the sling also has such an advantage because of its material texture Being soft, it can protect the lifting target very well and will not cause scratches or indentations during large-scale hoisting operations, thus giving it a wider space for use. It is precisely these Various reasons have just shaped the sling’s current glory.
