Put it temporarily inside.

Next, in FIG. 5, the hanging weight 22 and the car frame 21 are connected by a main rope 24 via a hoisting machine 23, and the hoisting machine 23 moves the car frame 21 and the hoisting weight 22 up and down. Movement. In this state, the work floor 60 is mounted on the car frame 21, and the car and the guide rails 8a, 1
Centering and fixing 0, 10a. When the work has been completed to just below the intermediate work scaffold 13, the intermediate temporary scaffold 15 on the intermediate work scaffold 13 is disassembled, the intermediate work scaffold 13 is removed, and another guide lifted by the electric winch 3 on the work floor 60. The lower end of the rail 8b is connected to the upper end of the guide rail 8a, and the upper end of the guide rail 8b is temporarily fixed to another intermediate work platform or an upper work platform 14 (not shown).

By repeating the above operation, the centering and fixing of the unified car and the guide rails 20 and 50 for the suspended weight can be completed over the entire travel of the hoistway 1 as shown in FIG. it can.

Next, the elevator and other components are mounted while moving up and down with the unified and centered and fixed car and hanging weight guide rails 20 and 50 as guides, thereby completing the installation work.

[0029]

As described above, according to the present invention, a number of guide rails corresponding to the capacity of the electric winch are lifted, and a hoistway corresponding to a multiple of the length from the lower end to the upper end of these guide rails.
