The invention discloses a wireless power pack of a hydraulic lift sub of a workover rig. An electric control mechanism is fixedly installed on one side of a lift sub body, and a hydraulic mechanism is fixedly installed on the other one side of the lift sub body. The weight of the electric control mechanism is equal to that of the hydraulic mechanism, a connecting cable between the electric control mechanism and the hydraulic mechanism winds around the rear side of the lift sub body. An antenna (ANT) of a receiver is installed on the outer surface of a box body of an anti-explosion control box of the electric control mechanism and corresponds to a signal antenna of a remote control unit. The electric control mechanism comprises a battery pack and the anti-explosion control box. According to the wireless power pack of the hydraulic lift sub of the workover rig, wireless remote control over the hydraulic lift sub of the workover rig is achieved, and no hydraulic pipelines or cables need to be added to a traveling and hoisting system; and the electric control mechanism is programmable, and different operation requirements are met.
