Description

Technical Field

[0001] This utility model relates to the technical field of lifting and transportation equipment, specifically to an anti-rotation multi-layer braided steel wire rope. Background Technology

[0002] Wire rope is a helical bundle of steel wires that meet the requirements of mechanical properties and geometric dimensions, twisted together according to certain rules. It consists of steel wires, a core, and lubricant. Wire rope is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, winding a certain number of strands into a helical shape. It is an important component for various purposes such as lifting, traction, tensioning, and load bearing. However, existing wire ropes are prone to rotation during use. When used for single-rod or high-lift lifting, the wire rope twists due to rotation, which not only affects the service life of the wire rope but also the efficiency of lifting operations and the safety of operators.
