CURRENT SITUATION AND ISSUES FOR FUTURE MAINTENANCE OF SUBWAY STATION ELEVATORS

Abstract

Due to changes in social structure such as declining birthrate, aging population, and diversity, it is important to develop elevators as barrier-free facilities for public transportation. Each companies try to response these social demands and realize the condition suitable for the host country of Olympic and Paralympic Games in 2020. Therefore, elevators will certainly increase in the future. On the other hand, maintenance and management costs increase as the number of elevators increases and this problem becomes heavy burden to the company. In order to reduce the burden of each companies, it is necessary to properly maintain to reflect the actual usage. The study focus on elevators at subway stations and illustrate the current situation and issues based on the number of operation times. Furthermore, the study clarify the relationship between the actual usage and maintenance cost to propose concrete countermeasures quantitatively for cost reduce control.
