Description

Technical Field

[0001] This utility model relates to the technical field of wire rope cutting devices, specifically a wire rope cutting device for replacing wire ropes in gantry cranes. Background Technology

[0002] Gantry cranes mostly run along crane tracks on the ground or buildings to carry out lifting and loading / unloading operations. One side of the running track is located on the ground, and the other side is located on a building above the ground. Wire ropes are increasingly widely used in production. Under normal circumstances, the wire ropes in gantry cranes wear out quite severely and often need to be replaced or cut.

[0003] In existing technologies, cutting wire ropes requires two people to work together in an open area using a sledgehammer and a chopping axe, resulting in a waste of manpower. Furthermore, improper operation can cause the cut wire rope to bounce up or wire rope debris to fly, posing a significant safety hazard to the operator. This task cannot be completed by non-professional maintenance personnel, is labor-intensive and inefficient, and personnel injuries frequently occur during the rope cutting process, posing a safety hazard. Therefore, it is necessary to improve the wire rope cutting device for replacing wire ropes on gantry cranes to solve the above problems. Utility Model Content
