The invention relates to the technical field of locomotive car lifting jacks, and discloses an electric car lifting jack movable bracket which comprises a machine base, a machine frame and a fixed bracket, the machine frame is vertically fixed to the machine base, a base is arranged on the machine frame in a sliding mode, the base moves in the height direction of the machine frame, the fixed bracket is arranged on the base, and the fixed bracket is arranged on the machine frame. The movable bracket is rotationally connected to the fixed bracket, the movable bracket has a vertical use state and a horizontal use state, when the movable bracket is in the vertical state, the top surface of the movable bracket is flush with the top surface of the fixed bracket, and when the movable bracket is in the horizontal state, the top surface of the movable bracket is flush with the top surface of the fixed bracket. And the top surface of the movable bracket is lower than the top surface of the fixed bracket. The minimum height from the supporting head of the movable bracket to the rail surface can be adaptively adjusted as required, and the lifting operation of various rolling stocks with small wheel diameters can be increased.
