However, it is known to form a monolithic product, transport it to the site with a large transport vehicle such as a trailer, and lift it with a large crane and install it on the site.
[0003]
[Problems to be solved by the invention]
In the former conventional construction method, what is incorporated only in the main body frame is carried in, and then the balustrade and wiring are incorporated locally. For this reason, there are many on-site work with poor environment, and it was not possible to obtain such an effect for shortening the installation work. Also, in the case of Patent No. 254345, assembling time at the site can be shortened by incorporating the balustrades at the upper and lower ends, but assembling work for other balustrades, wiring, etc. is done locally, It could not be said that it solved the former problem. In addition, the latter integrated loading can greatly reduce the installation work in that the installation work at the site is eliminated, but on the other hand, a large trailer is required for transportation, and there are a lot of restrictions in terms of road transportation. There was a problem.
[0004]
An object of the present invention is to provide a passenger conveyor installation method that does not require a large-sized transport vehicle for transportation and that can shorten the installation work.
