Description

Technical Field

[0001] The utility model relates to the field of slings, in particular to a mobile sling for hot-rolled coils. Background Art

[0002] Hot-rolled coils are made from continuously cast or initially rolled slabs. They are heated in a walking beam furnace, descaled with high-pressure water, and then fed into a roughing mill. The roughing mill then undergoes head and tail trimming before entering a finishing mill where computer-controlled rolling is performed. After final rolling, the coils are cooled with laminar flow and then coiled in a coiler to form straight-rolled coils. Transporting large hot-rolled coils requires a hoist for lifting and handling. However, existing hoists typically lack safety features, posing a safety hazard. Therefore, developing a new hoist for moving hot-rolled coils has become a pressing challenge for those skilled in the art. Utility Model Content
