Abstract

The invention discloses a large working platform lifting device which comprises a frame arranged under a working platform. Four lifts are installed between the frame and the working platform, and lifting synchronization devices are connected among the lifts and connected with a lifting driving device. When the height of the working platform is required to be adjusted, the lifting driving device is started, and the four lifts work synchronously and move up and down simultaneously under the effect of the lifting synchronization device to enable the working platform to be located in the horizontal state all the time. The large working platform lifting device is simple in structure, convenient to operate and capable of achieving accurate synchronous lifting.
