Title:
CABLE SYSTEM
Document Type and Number:
Japanese Patent JP2014064456
Kind Code:
A
Abstract:

To provide a cable system that can prevent slackening of a cable when a traveling body is finishing climbing, about to descend or finishing descending stairs, steps or the like.

A cable system A includes: a cable 3 connecting a base device 1 and a traveling body 2; a reel device 10 mounted on the traveling body 2; a motor controller for controlling a motor of the reel device 10; and an acceleration sensor 50 for detecting acceleration of the traveling body 2 in the vertical direction. When a reel 12 is rotating in the drawing out direction, the motor controller basically applies no motor power, and when the reel 12 is rotating in a winding direction, the controller basically applies rotational torque in the winding direction to the reel 12. Further, even when the reel 12 is rotating in the drawing out direction, if a differential value of the acceleration in the vertical direction from the acceleration sensor 50 exceeds a set value, the controller applies the rotational torque to the reel 12 in the winding direction.
