The lifting plate has a long stroke and a wide range of applications, and can be used in large, small and other three-dimensional garages. At present, in the existing lifting plate lifting device, it is necessary to match a high-power drive motor that meets the maximum lifting quality of the lifting plate, and drive the reel of the hoist to run through the reducer. The speed of the reel is limited after being decelerated by the reducer, so the lifting speed of the lifting plate is also low, which affects the access efficiency of the three-dimensional garage.

To increase the lifting speed of the lifting plate, an expensive high-speed lifting drive motor needs to be set up, which will greatly increase the construction and maintenance costs of the three-dimensional garage. In addition, the three-dimensional space occupied by the hoisting equipment is relatively large. In the three-dimensional garage, it is usually necessary to set up a separate layer of space for placing the hoisting equipment. It will significantly affect the space utilization of the three-dimensional garage.
