• [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
