After approaching, the other hand can control the remote control to lift the entire sling, and use the pressure of the steel pipe to generate friction between clamp 1 7 and clamp 2 8, thereby achieving the corresponding fixed clamping; when it moves to the specified position, it will directly under the steel pipe. After the steel pipe touches the ground, it will lift up the sling, and the pressure rod 10 will be returned to its original position, so that clamp 1 7 and clamp 2 8 are loosened, and the corresponding work is ended.

[0042] When working, the worker will wrap and fix the iron chain on the crane with the lifting ear 1, move the entire hoist above the steel pipe, control the crane to move the hoist below, so that clamp 1 7 and clamp 2 8 cooperate with each other and cover the steel pipe, and then the worker approaches the pressure rod 10, pushes the pressure rod 10 upwards, and uses the structural relationship to make clamp 1 7 and clamp 2 8 approach each other. After approaching, the other hand can control the remote control to lift the entire hoist, and use the pressure of the steel pipe to generate friction between clamp 1 7 and clamp 2 8, so as to achieve the corresponding fixed clamping; when it moves to the specified position, it will directly touch the steel pipe below. After the steel pipe touches the ground, it will lift up the hoist, and the pressure rod 10 will be returned to its original position, so that clamp 1 7 and clamp 2 8 are loosened, and the corresponding work is ended.
