In the process of our use, we need to tighten the U-bolt of the product, and the internal wire rope needs to be deflected to one-third of the degree, because in the process of being pressed, deformation occurs, so we also need to tighten it for the second time in the process of stress, so as to ensure the firmness of the joint. Secondly, when we fix the end of the wire rope, there are two methods to choose from and use. One is through a double barta, and the other is a single barta. A single bartack can be used at both ends of the product, or in the case of a double bartat, it is mainly used to fix the end of the rope.
