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 achievement marks a significant milestone, as the product has reached international advanced standards and filled a critical domestic gap in large-scale bridge construction equipment.
Beidaihe Tonglian Road and Bridge Machinery Co., Ltd. is a leading manufacturer and designer of specialized bridge construction equipment in China. Over the years, its products have played a vital role in major infrastructure projects across the country. In August 2005, the TP75-meter segmental erection machine produced by the company was successfully deployed on the world's first cable-stayed suspension bridge—the Sutong Bridge in Jiangsu Province. This marked a breakthrough in China's bridge construction capabilities.
In September 2019, the TLC100A special vehicle, independently developed by Qinhuangdao Tonglian Special Vehicle Co., Ltd.—a subsidiary controlled by Beidaihe Tonglian—achieved a one-time success during its trial run. This accomplishment ended China’s long-term reliance on imported special vehicles for road and bridge construction, showcasing the company’s growing technological independence.
The 900-ton railway bridge-passing machine that recently passed the type test is a large-scale bridge erection equipment specifically designed for China’s upcoming high-speed rail passenger line projects. After a rigorous international public bidding process, the China Railway 12th Bureau Group selected Beidaihe Tonglian Co., Ltd. as the manufacturer. With a safety load capacity of 900 tons and a total weight of 530 tons, this advanced machine is currently produced by only a few developed countries worldwide. It has also secured national patents, further emphasizing its innovation and technical excellence.
