[China's large-diameter and multi-support TBM Plateau Pearl off the line at CRCC] Recently, the domestic large-diameter multi-support TBM Plateau Pearl, jointly built by CRCC and the 14th Bureau of China Water Resources, rolled off the production line in the Changsha Second Industrial Park of China Railway Construction Heavy Industry. The equipment will be used for construction under extreme conditions such as high altitude, high ground stress, and super hard rock. The excavation diameter of TBM is 10.23 meters, the length of the whole machine is about 185 meters, the total weight is about 2300 tons, and the installed power is 8200 kilowatts. Editor/Ma Xue

• [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
