DEVICE FOR LIFTING STAGE BATTEN CAPABLE OF STOPPING THE BATTEN AT ONCE AT A DESIRED POSITION IN ORDER NOT TO CAUSE THE SLIP PHENOMENON OF A WIRE

摘要

PURPOSE: A device for lifting a stage batten is provided to stop the batten at once at a desired position in order not to cause the slip phenomenon of a wire, and to minimize the load of a driving motor according to the weight reduction of a balance weight. CONSTITUTION: The device for lifting a stage batten includes; a balance weight(140), arranged on one side of a driving pulley(120A), rotated by a driving motor(120); a batten(110), arranged on the other side of the balance weight(140); a wire(130), wound on the driving pulley(120A), so as to move the batten(110) and the balance weight(140) together; a first, second, and third motor-driven pulley(2,3,4), horizontally axis-connected with a lower supporting body(1) of the driving motor(120) in a parallel manner to the driving pulley(120A); and a motor-driven part(5), composed of a first, second, third, fourth, and fifth wire connection, correspondingly wound or crossed-wound on the driving pulley, and a first, second, third, and fourth motor-driven pulley(2,3,4).
