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 high-level bridge construction equipment.
Beidaihe Tonglian Road and Bridge Machinery Co., Ltd. is a leading manufacturer and designer of professional bridge construction equipment. Over the years, its products have played a vital role in major infrastructure projects across China. In August of this year, the company's TP75m segment-erecting bridge machine was successfully deployed on the world's first cable-stayed suspension bridge, the Sutong Bridge in Jiangsu. On September 19th, another breakthrough came when the TLC100A special vehicle, independently developed by Qinhuangdao Tonglian Special Vehicle Co., Ltd.—a subsidiary controlled by the company—achieved a one-time success. This development ended China's long-term reliance on imported specialized vehicles for road and bridge construction.
The 900-ton railway bridge-passing machine, which recently passed the 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 ultimately chose Beidaihe Tonglian Co., Ltd. to manufacture it. The machine has a safety load capacity of 900 tons and weighs 530 tons. Currently, only a few developed countries in the world are capable of producing such advanced equipment, and the product has already secured national patents, further highlighting its technological significance.
