LKS - MAX C - R Steel Wire Rope Excellent Fatigue Resistance For Excavator Push And Pull

Tips

Numerous studies and practices show that fatigue failure is the main reason affecting the service life of wire rope. The so-called fatigue failure is due to the formation of fracture sources within the steel wire of the wire rope under the action of alternating stress. These fracture sources gradually develop and expand, and finally lead to the fracture of steel wires (commonly known as "fatigue broken wire"). This fatigue fracture has no obvious plastic deformation. It has the characteristics of abrupt and is very harmful to the wire rope. Therefore, for a long time, people have reduced or eliminated the stress of the wire rope to enhance the fatigue resistance of the wire rope, thereby improving the service life of the wire rope.

To eliminate or reduce the stress of wire rope, first of all, we should make an objective analysis and understanding of all kinds of stresses in the wire rope. In this regard, many researchers at home and abroad have made a lot of theoretical and practical research and exploration, and have made great achievements. However, the stress of steel wire rope is very complex. The relationship between wire stress and stress and fatigue limit needs to be further studied.
In a variety of discussions, the stress of wire rope can be divided into two main categories: one is the stress produced in the production process of wire rope, but the stress produced during the working process of the wire rope.
