Walking-width widening transfer car

　　The traveling widening section carriage is a device specifically designed for highway tunnel widening construction. It plays a key role in the secondary lining concrete pouring of tunnels and water conveyance tunnels. This carriage adopts a full hydraulic system design, with automatic walking and hydraulic automatic positioning and demolding functions, which can significantly improve construction efficiency while ensuring construction quality.

　　The traveling widening section carriage mainly consists of a gantry and a formwork. The gantry is responsible for load-bearing, while the formwork is custom-designed according to the shape of the tunnel to ensure a tight fit with the tunnel wall. Driven by the hydraulic system, the carriage can move up, down, left, and right, flexibly adapting to various construction environments. In addition, the carriage is equipped with an electric speed reducer, further improving its walking stability and accuracy.

　　In widening section construction, the traveling carriage can effectively solve the problems of slow speed, poor lining surface quality, and high engineering investment that exist in traditional construction methods. Its use not only reduces labor intensity but also improves work efficiency, making the lining effect more aesthetically pleasing. At the same time, the carriage pays attention to details in its design, using reasonable processing and welding processes to ensure the accuracy of the overall external dimensions and welding quality.

　　In general, with its efficient, stable, and flexible characteristics, the traveling widening section carriage has become an important piece of equipment in highway tunnel widening construction. Its application has not only improved construction efficiency and quality but also injected new vitality into the development of the tunnel construction industry.
