FIG. 1 is a side view showing a state in the middle of an operation of a method of modifying an elevator according to an embodiment of the present invention. An existing operation panel 4 for operating an existing car 3 that can move up and down the hoistway 1 is provided in a machine room 2 formed above the hoistway 1. The other end of the existing electric wire 9 having one end connected to the existing operation panel 4 is connected to an existing car device 5 such as a landing device or a slowdown switch mounted on the existing car 3. Further, existing equipments 6, 7, 8 such as limit switches for each floor are electrically connected to an existing electric wire 10 having one end connected to the existing operation panel 4.

操作スイッチ１１間を接続しても良い。The modification of the elevator involves replacing the existing car 3, the existing operation panel 4, the existing wires 9, 10 and the like with new ones, and includes the work of removing the existing wires 9, 10 during the work. Here, the existing car 3 is to be used for the removal work of the existing wires 9 and 10. However, when the existing wires 3 are cut off while the existing car 3 is stopped on the first floor, the existing car 3 is no longer used. The car 3 cannot be moved up and down. Therefore, the other end of the temporary electric wire 12 having the operation switch 11 at one end is connected to the existing operation panel 4. That is, as shown in the main part circuit diagram of FIG. 2, the operation switch 11 has an ascending command button UP and a descending command button DN.
And a safety device check switch ES,
It is connected to an existing operation circuit CTL that raises and lowers the existing car 3 in the existing operation panel 4 of the machine room 2. The operation switch 11 may be provided in the existing car 3 in advance, and the existing operation panel 4 and the operation switch 11 may be connected by a temporary electric wire 12 laid along a different route from the existing electric wire 9.

The existing car 3 is raised or lowered using the command circuit. At this time, the existing car 3 can be used as a work scaffold to dismantle and remove the existing tower equipment 6, 7, 8 and the existing electric wires 9, 10, and it is not necessary to provide a work scaffold in the tower as in the conventional case. In addition, this makes it possible to reduce the labor and the working time, and also allows the existing equipment to be completely removed before installing the new equipment, thereby simplifying the work.
