The upper surface of each support plate 26 is fixedly connected to two first support columns 8. The side surfaces of each group of first support columns 8 that are close to each other are fixedly connected to a transverse telescopic rod 2.

[0025] The working principle of the utility model is:

[0026] When a material hoist for a construction project is used, first, the construction personnel need to control the transverse telescopic rod 2 through the operation box 5, so as to push the first support column 8 to connect the support plate 26 and the telescopic plate 12 to expand outward. Each telescopic plate 12 is provided with a slide groove 25 on both sides, and is slidably connected with two limit blocks 13 on the inner wall of the storage groove 15 provided on the outer surface of the lifting platform 11, so that the telescopic plate 12 is stretched. Then, when the construction personnel operate the transverse telescopic rod 2 to reach a certain length, the limit block 13 will prevent the telescopic plate 12 from continuing to expand outward, thereby preventing the telescopic plate 12 from falling off. Then, the construction personnel place the material to be lifted on the lifting platform 11 in the device. When using the device for lifting, the construction personnel need to control the start of the self-locking motor 9 through the operation box 5, thereby driving the rotation of the threaded rod 7, so that the nut 16 drives the slider 18 and the lifting plate 14 to lift. Finally, when it is lifted to a suitable position, the operation box 5 is operated to control the extension and retraction of the vertical telescopic rod 24, and the fixed plate 23 is pushed to quickly fix the position with the support leg 21, so that the construction frame does not move.
