PURPOSE:To accurately confirm the floor position of a cage even during outage by providing a means to display the floor position of the cage based on the positions of a winding drum, around which a main cable is wound and from which the cable is unwound, and the main cable. CONSTITUTION:The one end of a main cable 7 is locked to a winding drum 4 of a hoist 3 installed to a machine room 2, and a main cable 7 is extended upward from an opening part 9, formed on the elevation passage side, and an insertion port 11 formed between a cover 10 for covering the opening part 9 and the wall surface of the elevation passage. The other end of the main cable 7 is coupled to a cage through a return wheel at the upper end of the elevation passage, and the cage is elevated through forward and reverse of the winding drum 4. A display plate 15 is mounted on the cover 10, and when the main cable 7 is wound around and unwound from the winding drum 4, the main cable 7 is laterally moved in front of the display plate 15. Thus, by visually watching the main cable 7 and the display plate 15 in the machine room, based on an indication line 16 and a numeral 17 on the display plate 15, the floor position of the cage is mechanically displayed, and the floor position of the cage can be detected even during outage. |
