On some construction sites, fir or steel pipes are simply used for support or inverted chains are used for pull. For fir or steel pipe support, a stable fulcrum needs to be set at the bottom of the fir, but it is often difficult to implement the fulcrum on the supporting structure on site. Not only that, when using fir support, the contact stability between the top of the fir and the beam body is poor. Easy to slide or loosen; in the form of reverse chain pulling, there is also the problem that it is difficult to find the force point of the reverse chain, and the operation of the reverse chain is complicated and slow.

At present, there is no portable anti-dumping device for prefabricated beams that is simple, can be quickly adjusted in length, and has good stability.
