Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope releasing, in particular to a steel wire rope releasing device. Background Art

[0002] Wire rope is a rope made of multiple strands of steel wire, generally used in heavy load and large span situations. It has the advantages of high tensile strength, light weight and wear resistance. It is widely used in lifting, traction, transportation, ocean, petroleum and other fields.

[0003] In order to facilitate sales and transportation, wire rope manufacturers generally roll the wire rope on the spool for packaged sales. After purchasing, major manufacturers will remove the wire rope from the spool and install it on the equipment according to their own needs. However, when the workers release the wire rope from the spool, the wire rope wrapped around the spool is heavy as a whole, making it very difficult for the workers to turn the spool, making the operation extremely inconvenient and reducing work efficiency.

[0004] In view of the above-mentioned problems that when the steel wire rope is removed from the I-spool, the workers have difficulty in operation and the work efficiency is low, a steel wire rope releasing device is urgently needed. Summary of the Invention

[0005] Aiming at the problem that workers have difficulty in operating and have low working efficiency when removing the wire rope from the spool, the utility model proposes a wire rope releasing device to solve the above problems.
