At the construction site of the Yangsigang Yangtze River Bridge, the world's longest-span double-deck suspension bridge with four main cables, a smart mobile factory is working on building a 100-plus meters high tower just like on an assembly line.
CCCC's self-developed “vertical and mobile factory”, an integrated intelligent tower construction machine, has a total height of about 22.5 meters and weight of about 300 tonnes. It caters to the construction of various bridges. With the machine, a 100-plus meters high tower can be built story by story like 3D Printing. The labor cost is reduced, and the construction efficiency is increased by more than 4 times, with the construction speed averaging 1.3 meters per day.
