Bridge erection case of Jiangsu Zhonghai Bridge Equipment Co., Ltd.

Jiangsu Zhonghai Bridge Equipment Co., Ltd. (hereinafter referred to as "Zhonghai Bridge") has made remarkable achievements in the field of bridge construction with its advanced technology and rich experience. The company is located in Dantu High-tech Park, Zhenjiang City, and has strong production capacity and advanced manufacturing technology.

Domestic projects
Zhonghai Bridge has participated in many major domestic bridge construction projects, including Runyang Bridge, Hangzhou Bay Cross-sea Bridge, Sutong Bridge, Yellow Sea Bridge, Zhoushan Liandao Bridge, Nanjing Yangtze River Fourth Bridge, Quanzhou Bay Cross-sea Bridge, Hutong Yangtze River Bridge, Zhangzhou Bay Cross-sea Bridge, Fuzhou-Xiamen High-speed Railway Quanzhou Bay Railway Bridge, Wufengshan Yangtze River Highway-Rail Bridge, etc. These projects not only demonstrate the professional strength of Zhonghai Bridge in large-scale bridge construction, but also reflect its outstanding performance in technological innovation and quality control.

International projects
Zhonghai Bridge actively responds to the "Belt and Road" initiative and expands the international market. The company has participated in international projects such as the Maldives China-Maldives Friendship Bridge, the Brunei Cross-Sea Bridge, the Pakistan Hub Power Station, the Kenya-Malaysia Railway, and the Malaysia East Coast Railway. These projects have not only enhanced the international influence of China Ocean Bridge, but also contributed to the promotion of Chinese standards in the international market.

Technological Innovation and Application
China Ocean Bridge is the first company in China to achieve fully automatic welding of Bailey bridges. By introducing advanced automatic welding robot technology, the company has not only improved production efficiency, but also ensured the stability and consistency of welding quality. In addition, the company has also developed a 450-type Bailey bridge with a span of 83 meters and a load of 90 tons. The bridge has simultaneously applied for three sets of Chinese, American and European standard certifications, aiming to further enhance its competitiveness in the international market.

Quality and Safety
China Ocean Bridge always puts quality first. All products undergo strict quality inspections, and the main welds must pass ultrasonic flaw detection to ensure compliance with welding standards. The company has passed the ISO9001:2000 international quality system certification and has been awarded the honorary title of quality system management demonstration unit.

Through technological innovation and strict quality management, COSCO Bridge has provided high-quality bridge equipment and services for many large-scale bridge projects at home and abroad, demonstrating its professional strength and technological innovation capabilities in the field of bridge construction.
