  • the existing safety device mounted on the existing car is also replaced with a new safety device.
  • the guide surface of the existing car guide rail may be worn due to long-term contact with the guide device mounted on the existing car, and the coefficient of friction with the emergency stop device may be reduced. For this reason, when replacing an existing car with a new car, the existing car guide rail is also replaced with the new car guide rail.
  • the processing apparatus main body 7 is suspended in the hoistway 1 via the suspension member 8. Then, the processing apparatus main body 7 is moved along the car guide rail 2 while processing the braking surface 2 c by the processing tool 13. Therefore, the coefficient of friction of the car guide rail 2 with respect to the safety device 5 can be further optimized while the car guide rail 2 is installed in the hoistway 1.
  • the braking surface 2c can be uniformly processed over substantially the entire length of the car guide rail 2.

  • the first guide roller 15 is disposed above the processing tool 13, and the second guide roller 16 is disposed below the processing tool 13. Therefore, the parallelism between the outer peripheral surface of the processing tool 13 and the braking surface 2c can be more stably maintained. Accordingly, even when the car guide rail 2 is vertically inclined, bent, or undulated, the parallel relationship between the outer peripheral surface of the processing tool 13 and the braking surface 2c can be maintained.
  • the processing tool 13 is disposed at an intermediate position between the first and second guide rollers 15 and 16. For this reason, the moving direction of the processing tool 13 with respect to the frame main body 21 can be set to a direction perpendicular to the braking surface 2c. Thereby, the force for pressing the processing tool 13 against the braking surface 2c can be stabilized. In addition, it is possible to perform stable processing without generating unevenness of processing, that is, non-uniformity of the shaving amount.
  • the frame 11 is divided into a frame main body 21 and a frame divided body 22. Then, the frame spring 28 generates a force for moving the frame divided body 22 to the sandwiching position side. Therefore, the guide portion 2b can be stably sandwiched between the guide rollers 15, 16 and the pressing rollers 17, 18 with a simple configuration.
  • the processing tool 13 and the processing tool driving device 14 are movable between a processing position and a separation position.
  • the processing tool spring 33 generates a force to move the processing tool 13 and the processing tool driving device 14 to the processing position. Therefore, with a simple configuration, the processing tool 13 can be stably pressed against the braking surface 2c to perform stable processing. Further, by moving the processing tool 13 to the separated position, the processing apparatus main body 7 can be moved along the car guide rail 2 without processing the braking surface 2c.
  • the frame body 21 is provided with front end surface rollers 19 and 20. Therefore, the processing apparatus main body 7 can be smoothly moved in a stable posture along the car guide rail 2.
  • the outer peripheral surfaces of the guide rollers 15 and 16 are cylindrical, and the cross-sectional shapes of the outer peripheral surfaces of the pressing rollers 17 and 18 are arc-shaped. This automatically adjusts the outer peripheral surfaces of the guide rollers 15 and 16 to be parallel to the braking surface 2c.
