PURPOSE: A loader controller improves the rapidity, safety and operating efficiency of the work. CONSTITUTION: A controller comprises a vertical post(10), a horizontal transferring servo-motor(18), a vertical transferring servo-motor(20), encoders(22, 24) and a servo system. The vertical post(10) is movably mounted in a transport vehicle. The horizontal transferring servo-motor(18) provides motive power so that the vertical post(10) horizontally moves by a horizontal delivery screw(12) installed to a ceiling of the transport vehicle. The vertical transferring servo-motor(20) provides motive power so that a freight moving loader(16) vertically moves by a vertical delivery screw(14) installed to the vertical post(10). The encoders(22, 24) detect the rotation amounts of the servo motors(18, 20) and output control signal to stop the servo motors(18, 20) when the vertical post(10) and the freight moving loader(16) move to the objective location of a piling stand. The servo system outputs operation signals to the servomotors(18, 20) by the signals a user inputs to an operation box(26) and stops the servomotors(18, 20) by the objective location arrival signal of the encoders(22, 24).
