On August 23, in Changsha Second Industrial Park, the staff of the EPB conducted a technical discussion on the main bearing of the shield machine. Recently, the 7.6-meter-diameter main bearing independently developed by CRIC rolled off the production line, achieving another breakthrough in the key technology of super-large diameter main bearing, filling the gap in the domestic super-large diameter main bearing spectrum of the shield machine, and providing the domestic "heart" for the shield machine with a diameter of 16 meters and below.
