The above first to fifth steps are procedures for newly assembling a passenger conveyor. However, for a situation where an installed passenger conveyor is to be repaired or improved, the above-mentioned maintenance system does not necessarily need to be supported together with the frame of the passenger conveyor, and the maintenance system may be supported by a fence or the like. In addition, in the above embodiments, the entire weight of the maintenance system is completely supported by the side of the passenger conveyor. However, when the maintenance system is large, the maintenance system may be installed on the passenger conveyor, on the upper and lower floors, and on steps. Therefore, the weight of the maintenance system is supported by the floor and stairs, and the passenger conveyor side is only used to prevent the maintenance system that has been set up from falling. As mentioned above, according to the present invention, the maintenance of the passenger conveyor can be performed on the floor surface without the need to set up a script body. Compared with the conventional maintenance system, the number of components of the maintenance system is smaller, and its structure can be simplified. Case. As a result, process costs can be reduced. In addition, compared with the conventional maintenance system, the total volume of the maintenance system of the present invention can be reduced, because the script body can be omitted, and the handling and management of transportation and management can be extremely simple. In addition, compared with the conventional maintenance system, the area around the passenger conveyor can be kept more spacious, so the restrictions on the sidewalk area can be moderately regulated.
