• [The 10000 ton rotating beam of the Cross Ningxi Railway has successfully rotated]
• On April 21, 2026, the 19000 ton rotating beam of the Hewu High speed Railway over the Ningxi Railway completed an "aerial turn" and successfully crossed the Ningxi Railway. The weight of the beam is 19157.8 tons, and the rotation accuracy requirement is that the error should not exceed 10 millimeters. Due to its proximity to busy main roads, the construction team relies on an intelligent monitoring platform to monitor posture, stress, and wind speed in real-time, and cooperates with a synchronous traction system to achieve precise counterclockwise rotation and positioning. The successful transformation marks significant progress in the project.Editor/Cheng Liting

• [The Tianjin section of the Datong Tianjin Nante High Voltage Project is fully constructed]
• On April 21, 2026, the Tianjin section of the Datong Tianjin Nante High Voltage Project will be fully constructed. The construction adopts unmanned aerial vehicle guidance and mechanized traction, crossing the Changshen Expressway to achieve uninterrupted traffic. This project is a national strategic channel for "West East Electricity Transmission", planned to be put into operation in June 2027, with an annual transmission of over 14.6 billion kilowatt hours of clean electricity and a reduction of 11.81 million tons of carbon dioxide emissions. A new 171 kilometer railway line will be built in Tianjin, and a 7 billion yuan investment will drive an industrial chain worth over 14 billion yuan, providing solid support for the green development of the Beijing Tianjin Hebei region.Editor/Cheng Liting
