The 900-ton railway bridge-passing machine, jointly developed by Hebei Beidaihe Tonglian Road and Bridge Machinery Co., Ltd. and the Railway Fifth Survey and Design Institute, has successfully passed the type test organized by the General Administration of Quality Supervision, Inspection and Quarantine in Beidaihe. This groundbreaking product has reached international advanced standards, filling a critical domestic gap in high-tech bridge construction equipment.
Beidaihe Tonglian Road and Bridge Machinery Co., Ltd. is a leading manufacturer specializing in the design and production of bridge construction machinery. Over the years, its products have played a vital role in major infrastructure projects across China. In August this year, the TP75m segment-erecting bridge machine was successfully deployed on the world's first cable-stayed suspension bridge, the Sutong Bridge in Jiangsu. Just a month later, on September 19th, the TLC100A special vehicle, independently developed by Qinhuangdao Tonglian Special Vehicle Co., Ltd.—a subsidiary of the company—achieved a successful one-time trial run, marking the end of China's reliance on imported specialized vehicles for road and bridge construction.
The 900-ton railway bridge-passing machine, which recently passed the rigorous type test, is a large-scale bridge erection system specifically designed for China's upcoming high-speed rail passenger line projects. It was selected through an international public bidding process, and the China Railway 12th Bureau Group finally awarded the manufacturing contract to Beidaihe Tonglian. With a safety load capacity of 900 tons and a total weight of 530 tons, this advanced equipment is currently produced in only a few developed countries worldwide and has already been granted national patents. Its successful development represents a major milestone in China's efforts to build self-reliant and technologically advanced infrastructure solutions.
