From December 4th to 6th, 2020, the 3rd Zhejiang International Smart Transportation Industry Expo was held at Hangzhou International Expo Center.

With the theme of "New Journey to a Powerful Country in Transportation, New Momentum for Industrial Development", this exhibition is committed to creating a national comprehensive transportation industry cooperation platform with international influence. Well-known domestic and foreign companies such as CRRC, CRRC, the Chinese Academy of Railway Sciences, Huawei, and Tesla Motors are invited to participate in this exhibition.

China Railway Science and Industry Group, as a core member of China Railway Industry, was invited to bring new products such as "New Era" suspended rail transit (empty rail) system, two-wheel milling and milling machine, 1000-ton bridge erector, resonance crusher, etc. The brilliant technology debut showcased the latest achievements of China Railway Science and Industry Group in the field of smart transportation construction guided by the "three transformations".

In June 2020, the Enshi Qingyunya Project, the first domestic "air track" commercial operation line undertaken by China Railway Science and Industry Corporation, has started. On November 9, "Empty Track" successfully completed the unmanned operation test. At present, the "empty rail" prototype car has a smooth and safe operation mileage of more than 1,900 kilometers on the Wuhan Jiangxia test line. China Railway Science and Industry has now fully mastered the complete set of suspended rail transit system technology.

China Railway Science and Engineering has fully mastered the core technology of double-wheel milling. China Railway Science and Technology double-wheel milling equipment is currently widely used in the construction of underground diaphragm walls such as bridges and subways. It has successively completed Guangzhou Metro Line 11 and Construction of underground continuous walls in projects such as Line 18 and Shenzhen Chunfeng Tunnel. The domestic double-wheel milling has hard construction quality, high precision and good efficiency, which effectively guarantees the safety of the project, the quality of the wall and the construction progress, and has been widely recognized by the industry.

The 40-meter-span 1000-ton racking equipment displayed in the exhibition area is one of the model products of science and technology innovation of the Science and Technology Group, leading the upgrade and breakthrough of high-speed rail box girder racking technology. The single-span beam frame mode is adopted. The trolley and the beam trolley on the beam transporter simultaneously drag and take the beam, and walk through the hole in a walking style. The successful use of this equipment marks the third major breakthrough in my country's high-speed rail construction technology.

The successful development of the resonance crusher broke the foreign monopoly, solved a series of problems in the regeneration of old cement roads, and the overall technology reached the international leading level.

At this exhibition, a promotional video for China Railway's new standard rail transit was released, and relevant units exchanged products and technologies on the "New Times" series of new standard rail transit vehicles, high-speed maglev turnouts, and the world's largest cross-section rectangular shield machine. . Leaders such as Tan Shunhui, Deputy General Manager of China Railway Industry, and Lin Chengchao, General Manager of China Railway Science & Industry, attended the exhibition and gave guidance, accompanied by relevant personnel from the Industrial Brand Operation Department and China Railway Science & Industry Group.Editor/Xing Wentao
