Lifting joints are a factor affecting the performance of lifting equipment.
lifting spreaders are divided into lasso, suspender rigging and chain lasso. The structure and size of wire rope rigging have been standardized, generally consisting of single-leg rigging, double-leg rigging, three-leg rigging and four-leg rigging. It can also be said that it consists of a single wire rope combination rigging and a single wire rope combination rigging of the same nominal size.
The existing connection forms are mainly interpolation connection, crimp connection and casting connection. In the rigging production process, traditional production methods include casting and welding. There are many different welding methods, such as: friction stir welding, brazing, manual arc welding, electron beam welding, etc. In addition, the manufacturing method of the rigging joint also includes metal bonding method, split forging and welding combination method.
The anchor connection stress is mainly unstable load, and its main failure form is fatigue failure. The fatigue failure areas are mostly sockets, and fatigue cracks are easily generated on the outer surface and sockets, and fractures are prone to occur after the cracks spread. Especially in the tongue, due to the concentration of stress, it is more sensitive to stress and has a small area of stress, which is a part that is prone to fatigue damage.
Suspension joints are a factor affecting the performance of lifting spreaders. While maintaining and testing spreaders, don’t forget to maintain and inspect the lifting joints to avoid unnecessary trouble!
