According to a recent report in *Shaanxi Daily*, a 900-ton transport and racking system, developed by China Railway Construction Machinery Research and Design Institute Co., Ltd. and manufactured by Shanxi Construction Machinery Co., Ltd., was recently completed in Juning, Anhui Province. This advanced equipment played a key role in the construction of the Hefei-Nanjing High-Speed Railway Passenger Dedicated Line. It marked a historic milestone as the first successful installation of a 32-meter, 900-ton double-hole box girder, setting a new precedent in China's railway bridge construction history. The achievement highlights the country's growing capabilities in producing large-scale bridge construction machinery, reaching a level that is now considered among the best domestically.
The 900-ton system consists of the YL900 beam transporter and the JQ900A bridge erection equipment. Designed specifically for high-speed rail projects, this cutting-edge technology represents a major breakthrough in China’s infrastructure development. With its outstanding technical performance, safety features, and practical application, it has become a benchmark in the industry. For the first time ever, this kind of equipment was used to erect a 32-meter double-hole box girder on a national railway project, demonstrating the nation’s increasing self-reliance and technological advancement in the field of civil engineering. This development not only boosts confidence in domestic manufacturing but also positions China as a global leader in high-speed rail construction technology.
