Further, the diameter of the raising stand 13 is gradually reduced from the lower end to the upper end.
[0012]
Next, the operation will be described. When the elevator is installed or the main ropes 14 are replaced, the winding body 14A and the main rope pay-out device are carried into, for example, the landing floor 15 on the top floor. The main rope extension device can be disassembled, and is disassembled into a base 1 on which the universal wheel device 5 is mounted, a rotating shaft 4, a plurality of receiving plates 12, a plurality of raising stands 13, and an upper plate 11. It is carried on the landing floor 15.
[0013]
When assembling the main rope extension device, first, the base 1 is placed on the landing floor 15 so that the non-slip member 2 contacts the landing floor 15. Next, the rotation shaft 4 is inserted into the shaft support portion 3, whereby the rotation shaft 4 is erected on the base 1. Thereafter, the first-stage receiving plate 12 is placed on the universal wheel device 5, and the raising stand 13 is further placed on the receiving plate 12. At this time, the receiving plate 12 and the raising stand 13 are penetrated by the rotating shaft 4.
