This patent mainly uses a hydraulic cylinder, a hydraulic rod and a moving wheel. When the position needs to be adjusted, the hydraulic cylinder supplies oil to the hydraulic rod, and the hydraulic rod extends to push the moving wheel out of the mounting hole, and then the main bracket of the equipment is pushed to move the entire equipment to a suitable position. It is convenient to adjust the position within a small range of the lifting device when in use. The structure is simple and easy to use, which solves the problem that the equipment is bulky and heavy, and difficult to move after installation. However, the device may shake when rising or falling, and items may fall. For this reason, we propose a lifting device for construction engineering. Utility Model Content
