The inspection vehicle track and bracket, single round column pier bracket (span 32.7m, 24.7m), and hyperbola round end pier bracket (d=2m, 2.3m, 2.5m, 2.8m) for Jinhu high-speed railway, fabricated and installed by the company in 2009 and 2010. The project won great reputation for quality and design. The following are its technical requirements:
