The overall combination of the cross-shaped main beam 201 and the auxiliary beam 202 makes the support mechanism 2 more stable, and the frame 4 includes two load-bearing rods 401, and a plurality of mounting holes 402 are opened on the load-bearing rods 401 along the length direction thereof, and the mounting holes 402 extend along the length direction of the load-bearing rods 401. The number of mounting holes 402 can be set to three, and the ends of the mounting holes 402 are arc-shaped. Two support rods 404 are connected between the two load-bearing rods 401, and the two support rods 404 both pass through the steel cage 1. Hanging the steel cage 1 on the support rods 404 facilitates the later hoisting of the steel cage 1, and the parts of the two support rods 404 extending out of the steel cage 1 can pass through the mounting holes 402 on the load-bearing rods 401.

The spacing between the support rods 404 will be changed, and the mounting hole 402 extends along the length direction of the load-bearing rod 401. Therefore, the position of the support rod 404 inside the mounting hole 402 can also be adjusted to adapt to different types of steel cages 1. The subbeam 202 is connected to the load-bearing rod 401 of the frame 4 through the connecting mechanism 3. The connecting mechanism 3 can move on the subbeam 202 and the position can be fixed. When the connecting mechanism 3 moves on the subbeam 202, the load-bearing rod 401 connected to the connecting structure will also move with it. At this time, the spacing between the load-bearing rods 401 will also change. The support rod 404 adapts to the change in the spacing between the load-bearing rods 401 by adjusting the length of the support rod 404 extending into the mounting hole 402, which has a better adaptation effect on different types of steel cages 1. The connecting mechanism 3 is provided with a lifting ear 302 for connecting the lifting device. After the support mechanism 2, the frame 4 and the connecting mechanism 3 are adjusted according to the size of the steel cage 1, the lifting device can lift the steel cage 1 by connecting the lifting ear 302.
