Definitions

  • An indicating lamp 23 serving as display means is connected to the detection portion 17.
  • the indicating lamp 23 is lit up when the movable-side contact 21 comes into contact with one of the fixed-side contacts 22a and 22b.
  • the movable-side contact 21 is open away from the fixed-side contacts 22a and 22b, and the indicating lamp 23 is off.
  • the suction force acting between the main rope body 11 and the magnet 20 increases, so the magnet 20 is attracted toward each of the main ropes 6 sides.
  • the magnet 20 is also attracted in a moving direction thereof. Then, when the coating body 12 is reduced through abrasion to a predetermined thickness, the movable-side contact 21 comes into contact with one of the fixed-side contacts 22a and 22b.
