The invention relates to the technical field of hoisting devices, in particular to an electric movable gantry crane driven by an accumulator. A walking portion is arranged at the bottom end of a gantry. A first motor is arranged at one end of a cavity of a cross beam. A threaded rod is connected to the power output end of the first motor. A horizontal movement base is in threaded connection to thethreaded rod in a sleeving manner. Rolling wheels are mounted on the front face and the back face of the horizontal movement base correspondingly. The bottom ends of the rolling wheels are in rollingcontact with the bottom face of the cavity of the cross beam. A corner driving portion is fixedly connected to the lower surface of the horizontal movement base. The top end of the corner driving portion is in sliding and clamped connection with a groove which is formed in the middle of the lower surface of the cross beam and extends in the axial direction. A rotating disc is connected to the bottom end of the corner driving portion in a rotary manner. A second motor is arranged in a cavity of the corner driving portion. The power output end of the second motor is connected with the circle center of the rotating disc in a sleeved manner. The top end of a hoisting portion is fixedly connected to the edge of the rotating disc. By means of the electric movable gantry crane, the problem thatat present, the angle cannot be adjusted safely, conveniently and fast when an object hoisted by an electric gantry crane falls is solved.
