The invention discloses a lifting device for power maintenance. The lifting device comprises a base, steps and a battery pack, wherein self-locking rolling wheels are arranged on the left side and theright side of the lower end face of the base, rotating rods are rotationally connected into the base, meanwhile, the outer ends of the rotating rods are provided with abutting columns in a penetrating mode, fixed supports and first hydraulic cylinders are fixed to the left side and the right side of the upper end face of the base, the first hydraulic cylinders are arranged on the inner sides of the fixed supports, second hydraulic cylinders are fixed to the inner bottoms of first movable supports, the upper sides of the second hydraulic cylinders are connected with second movable supports through second piston rods, the steps penetrate through a through hole, and the through hole is formed in the bottom of a bearing frame. According to the lifting device for power maintenance, after the device is moved to a required place, a worker can manually rotate the rotating rods towards the outer side under the action of shaft columns, and then the abutting columns can be screwed downwards until the abutting columns abut against and are fixed to the ground, so that the device is placed more stably, and the safety of the device is improved conveniently.
