Abstract

The invention discloses an electric power overhaul lifting platform. The electric power overhaul lifting platform comprises a platform base and a lifting table arranged above the platform base. At least four pressure sensors are arranged on the lifting table at equal intervals. A control box is arranged on the platform base. A control circuit is arranged in the control box. The pressure sensors are connected with the control circuit through wires. According to the electric power overhaul lifting platform, four hydraulic cylinders are adopted to push a support to move in the direction of a diagonal line of the platform base, when the pressure sensors detect that the weight on the lifting table is not even, the supporting position can be adjusted by adjusting the position of the support, and therefore potential safety hazards caused by the unstable gravity center of the lifting table can be avoided.
