The utility model provides a 500 kV overhead ground wire lifting tool, which comprises a screw rod, a hook, a hanging plate and a connecting piece thereof. The lifting tool is characterized in that the upper end of the screw rod (2) is fixedly connected with the hook (1) through a hook hitch clevis (4b). The lower end of the screw rod (2) is fixedly connected with the hanging plate (6) through hanging plate hitch clevises (4a). Two hitch clevises on the hanging plate are clamped on the tower of a power transmission line. Through rotating the moment arm of the screw rod, the upper and lower sections of the screw rod are elongated, so that a to-be-processed overhead ground wire is conveniently hooked by the hook. Through rotating the moment arm of the screw rod for a second time, the screw rod is retracted in length, so that the ground wire clamped in the hook can be lifted to a place to be conveniently handled with. The lifting tool is convenient to use. By means of the lifting tool, the occurrence of safety r
