When the steel bar sling is hoisted, the length of the steel wire rope can be adjusted by adjusting the connecting position of the steel wire rope self-locking device and the second steel wire rope, and then the height of the anti-falling barrel is adjusted, so that the lower part of the hoisted steel bar is positioned in the anti-falling barrel. When the steel bar is hoisted to a specified unloading position, the height of the anti-falling barrel at the bottom is adjusted through the steel wire rope self-locker, so that the anti-falling barrel is separated from the steel bar. If the vertical steel bars fall off in the hoisting process, the vertical steel bars can fall down into the anti-falling barrel, and the anti-falling barrel can hold the gliding steel bars and cannot fall down to hurt people. After the anti-falling barrel is transferred to an operation point, the anti-falling barrel is stressed and cannot directly unload materials, and a shackle can be unfastened to unload the reinforcing steel bars or a steel wire rope self-locking device can be opened to unload the reinforcing steel bars.

Has the advantages that:

by adopting the anti-falling pallet for vertically hoisting the steel bars, workers can reduce the height of the anti-falling barrel by adjusting the height of the steel wire rope self-locking device; when the hoisting operation of the reinforcing steel bars is not influenced, the reinforcing steel bars can be conveniently unloaded, the safety protection effect can be achieved, and the safety accidents are avoided.
