[0002] At present, the prefabrication of box girders in engineering construction has become a very mature process. The assembly of prefabricated formwork directly affects the progress of box girder prefabrication, especially the assembly of outer formwork. The outer formwork of prefabricated box girders is large and heavy, and it is difficult to control the balance during lifting. It requires the cooperation of multiple people to assemble the formwork into place. There are many techniques for assembling the outer formwork, such as shoulder pole type, ring type, multi-point type, etc.

[0004] In the prior art, if the outer mold falls off the equipment during the process of hoisting and moving the outer mold, it will not only cause damage to the outer mold, but also threaten the life and health of the workers. Utility Model Content
