[0002] Steel cages for highway construction are common building materials in civil engineering, mainly used to strengthen the strength and stability of concrete structures. Steel cages are cage-shaped structures made of welded or tied steel bars, and are widely used in the reinforcement and protection of highway roadbed slope protection, bridge pier foundations, drainage ditches, culverts and other parts. It can effectively improve the bearing capacity and seismic performance of concrete structures and ensure the safety and stability of the structure.

[0003] At present, for the assembly of prefabricated component reinforcement cages, a gantry crane (or telescopic crane) is used to suspend the reinforcement cage at the assembly construction site.

[0004] However, during the hoisting process, since the steel cage is heavy and the hoisting point is suspended by a single hook, the steel cage may be deformed or overturned during the hoisting process. Based on the above problems, we provide a prefabricated steel cage hoisting device for highway construction.
