Description

Technical Field

[0001] The utility model relates to the technical field related to steel wire ropes, in particular to a steel wire rope with a compacted strand process. Background Art

[0002] Wire rope is a spiral bundle of steel wires twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. It is first twisted into strands from multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center.

[0003] Steel wire ropes are widely used in hoisting, transportation, engineering construction and other fields. In some special applications, steel wire ropes with higher strength, better wear resistance and oil storage performance are required to meet special engineering needs. Traditional steel wire ropes are usually twisted together with multiple strands of steel wires. The technology and structure are often restricted and it is difficult to meet some special performance requirements. The steel wire rope industry is also constantly pursuing higher performance. For this reason, we provide a compacted strand process steel wire rope. Utility Model Content
