Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a wire rope threading mechanism. Background Art

[0002] A wire rope is a helical bundle of steel wires twisted together according to specific rules, with steel wires that meet the required mechanical properties and geometric dimensions. It consists of steel wires, a core, and lubricating grease. Wire rope is first twisted into strands from multiple layers of steel wire, and then a certain number of strands are twisted into a spiral around the core. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing. Wire ropes are high in strength, light in weight, operate smoothly, are not prone to sudden breakage, and are therefore reliable. Some wire ropes require one or both ends to be fixed into a loop with connectors for use as slings, spreaders, or other applications. Currently, some wire ropes are produced through manual clamping, which is inefficient and reduces production efficiency. Utility Model Content
