Abstract

PURPOSE: To make the life span of a cable long with simple structure by mechanically detecting the hanging length of the feeder cable to a gondola from the gondola rise and fall mechansim and adjusting the feeder cable winding tensile force by its detection value.
CONSTITUTION: A gondola 1 rises and falls by the wire 4 wound by a winch 3 through a pulley 2 and the feeder cable 6 to the gondola 1 is wound by the reel 8 which is driven by a torque motor 9 through a pulley 7. The turning force of the torque motor 9 is controlled by the voltage regulator 11 which is connected by a wire 10. The hanging length l of the feeder cable 6 is converted and detecting by the angle of revolution of a wheel 14 which is connected from the winch 3 through a speed changer and decelerator 13 and the output voltage of the voltage regulator 11 is changed in accordance with the angle of rotation of the wheel 14.
