Description
Technical Field

[0002] In actual on-site production, when replacing catenary cantilever insulators, a hand winch is mostly selected as the force-bearing tool. The wire sleeves are respectively fixed on the pillar and the cantilever, the hand winch is used to connect the two wire sleeves, and then two operators cooperate to shake the hand winch to unload the force of the cantilever, so as to complete the replacement of the cantilever insulator. This replacement method has the following four disadvantages:
[0003] (1) The hand winch is heavy in structure, and consumes a lot of physical energy for the operator. The hand winch itself has a ratchet structure and a metal chain, resulting in a bulky body structure. When the operator hangs and takes it, it consumes a lot of physical energy, which directly affects the physical state of the operator and increases the safety hazard.
