た。2. Description of the Related Art Conventionally, when an existing elevator that has been delivered in the past is modified into a new elevator, for example, Japanese Patent Laid-Open No. 61-5507.
As described in Japanese Patent Publication No. 9, first, the parts to be replaced and the parts to be added are carried by using the existing elevator, and the car is disassembled and removed while the counterweight is positioned on the shock absorber in the pit. The main rope removed from the frame is lowered to the pit and removed. After that, the hoisting machine and control panel are also removed from the machine room. Next, the parts of the new elevator, which had been previously transported from the top floor, were attached, the elevator was put into operation, and the removed parts were then carried out by the new elevator to complete the modification work.

ばならず、無駄も多かった。In such a conventional remodeling method, it takes about 2 weeks from the start of work to the operation state by the new elevator, and the service operation must be stopped during that time. Therefore, in the case of a lift installed alone, the user is forced to rely on the stairs, which causes a great deal of trouble. Further, in the above-mentioned conventional example, during the work by this remodeling method, provision of a temporary elevator is provided for the convenience of the user, but a great deal of effort must be spent for preparation, installation and disassembly of this temporary elevator. Of course, there was a lot of waste.
