We embarked on an intriguing endeavour to construct a versatile maintenance platform equipped with multiple hoists, specifically tailored for the repair and modernisation of city trains. At the heart of this initiative lies the seamless replacement of AC units, modernisation of pantograph systems, and the installation of new cabin windows. Ensuring worker safety amidst the intricate machinery was paramount in our design process. Collaborating closely with the existing infrastructure, including the HV track lines spanning the building, we meticulously integrated safety measures to prevent operation while the HV lines are active. Incorporating gap closure panels and a secure dual-key system, we guarantee the utmost safety for personnel working on the moving gantry, mitigating potential hazards, and facilitating smooth operations.
