Metro maintenance depots present unique material handling challenges: extreme height restrictions (often below 5 meters), dense infrastructure (piping, ventilation, and electrical conduits), and precision operations for heavy components like train bogies (weighing 5-10 tons) and car bodies. Conventional overhead cranes struggle here, sacrificing hook height for structural bulk. Dongqi Crane’s specialized low headroom double girder […]
