Busan Transportation Corporation Completes Metro Escalator Safety Device Upgrades Six Years Ahead of Schedule
Safety Enhanced at Mangmi and Baesan Stations Through Technology Development
283 Billion KRW Invested in Challenging Construction Projects
Busan Transportation Corporation (President Lee Byungjin) has completed the safety device upgrade project for 658 escalators installed at all stations on Busan Metro Lines 1 to 4, six years ahead of the original schedule.
Despite financial difficulties and a global parts supply shortage, the corporation's proactive measures for citizen safety are being recognized as a success.
This project involved the installation or replacement of key safety components on aging escalators, such as overspeed and reverse motion prevention devices, main brakes, and auxiliary brakes, with a total investment of 28.3 billion KRW.
The corporation began the upgrade work in 2019 with plans to complete it sequentially by 2031. However, by consulting with Busan City and the Ministry of the Interior and Safety to secure additional national and municipal funding, and by introducing a dual-track strategy based on the degree of aging, the project timeline was significantly shortened.
Mangmi Station and Baesan Station on Line 3 have ceiling heights exceeding 19 meters, which previously made it impossible to install overspeed and reverse motion prevention devices. After three years of collaboration with the manufacturer, the corporation developed new parts in-house and obtained the necessary safety certifications, successfully overcoming this challenging issue.
