The invention discloses a fully automatic power equipment secondary handling platform tool capable of automatic centralization, include that box, A base is welded on one side of the box body, and a cross bar is arranged on one end of the base far away from the box body, An upper pin shaft of that cross bar is connected with a gantry frame, the upper pin shaft of the box body is connected with a hydraulic cylinder, the output end of the hydraulic cylinder is connected with the pin shaft of the gantry frame, a support is vertically and equidistantly bolted to the upper end of the gantry frame, acurved outer plate of a hollow structure is weld on the support, and two strong springs are symmetrically welded on both ends of the curved outer plate. The utility model has the advantages that thehydraulic cylinder is used to drive the gantry to rotate in the degree direction with the horizontal bar as the fulcrum, and the gantry is clamped and supported by the arc-shaped bracket in the rotating process, so as to reduce the vibration amplitude when the gantry is centralized; the hydraulic cylinder is used to drive the gantry to rotate in the degree direction with the horizontal bar as thefulcrum; The curved inner plate is clamped and fixed by the elastic force of the strong spring, which is beneficial to further improving the stability of the electric power equipment in the short-distance transportation process.
