The illegal use of flat lifting belt will bring the consequences of fracture, and the cause of fracture can be roughly divided into two kinds, one is the pull of overload, the other is cut off by sharp edges and corners, so how to judge the two different fracture modes?
Although both are fractures, there are great differences in the fracture points of the two fractures. Let's have a brief understanding of them below.
First of all, we first to look at the caused by overload hoisting belt snap, super load when using fracture embodied in for sewing thread touch crack sound, then the product fragile place also is the eye part will tear, fracture surface is very irregular, filaments showed different length of the flash, and the distorted state, this is shown by the snap features. Then traces is cut by a sharp object, embodied the characteristics of this approach for fracture appearance appears as a straight line, is flat lifting belt around constantly in the process of friction, presented the fracture characteristic is neat, broken filaments almost the same length, lifting with no obvious distortion, which is cut's characteristics.
Whether it is pulled or cut off, it is bound to be not checked before use, so whether it is the load problem or the detection of the connection fixed point should be done, so as to effectively prevent the fracture of the flat lifting belt.
