Description

Technical Field

[0001] This application relates to the field of lifting devices, and in particular to a self-balancing C-hook combination lifting device with telescopic function. Background Technology

[0002] C-hooks are frequently used in the steel industry when lifting steel coils or wire rods. Since a single C-hook can only lift one coil at a time, multiple C-hooks are often combined to form a spreader, enabling the lifting of multiple coils simultaneously. However, ordinary C-hook spreaders can only perform balanced lifting and cannot handle uneven loads. When the weight of the coils on both sides is inconsistent, the spreader will tilt, resulting in low lifting efficiency and potential safety hazards. Furthermore, when lifting steel coils onto ships at ports, fixed C-hook spreaders, due to their fixed length, cannot adapt well to vessels of various widths, thus limiting their application.
