Lifting belt is a rope commonly used in hoisting operation. It has soft texture but excellent load-bearing performance. It can bind heavy objects to assist hoisting. Abnormal rope use time will cause problems, and fracture is the biggest problem of hoisting. There are two kinds of fracture. One is the fracture caused by the decline of rope performance due to the accumulated use over time, which belongs to tension fracture; The other is the cutting caused by the friction of sharp objects.
Many people can't tell the difference between pulling and cutting the lifting belt, and then attribute it to the poor quality of the rope, but in fact, the two are different. Breaking is caused by the natural stress of the rope. This situation may be caused by the quality problem of the rope, but it may also be caused by overload. The cutting is due to some wounds on the surface that affect the internal continuity of the fiber. When under tension, both sides of the wound continue to bear external forces, resulting in the cutting phenomenon. This is due to the wrong use of the operator. When the lifting object has sharp edges and corners, or there are sharp places around the lifting, it will cause destructive cuts to the rope, To protect the rope, a protective lining can be used to protect the rope.
The above is the relevant introduction of the two fracture conditions of the lifting belt. Do you know?
