The 900-ton railway bridge-erecting 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 milestone marks a significant achievement, as the product has reached international advanced standards and filled a critical gap in domestic infrastructure technology.
Beidaihe Tonglian Road and Bridge Machinery Co., Ltd. is a leading manufacturer specializing in bridge construction equipment. Over the years, its innovative products have played a vital role in major infrastructure projects across China. 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 bridge construction technology.
In September 2005, 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 specialized vehicles for road and bridge construction, showcasing the company’s growing technical capabilities.
The 900-ton railway bridge-erecting machine that passed the type test is a large-scale, high-performance equipment specifically designed for China’s upcoming high-speed rail projects. After a rigorous international bidding process, the China Railway 12th Bureau Group selected Beidaihe Tonglian Co., Ltd. as the manufacturer. The machine can safely carry a load of 900 tons and weighs 530 tons. Currently, only a few developed countries have the capability to produce such equipment, and the technology has already been granted national patents in China. This development not only strengthens the country’s infrastructure industry but also enhances its global competitiveness.
