[CRCC Inclined Shaft Tunneling Machine Rolled Off the Production Line] On April 20, 2023, a tunnel boring machine that can achieve 50° ultra-large slope climbing, 6.53 meters and 8 meters variable diameter excavation rolled off the production line in Changsha First Industrial Park of China Railway Construction Heavy Industry. The variable-diameter inclined shaft rock tunnel boring machine marks another new breakthrough in my country's underground construction site equipment, filling the gap in the field of full-section mechanized construction equipment for super-large slope two-stage inclined shafts in China, and further enriching the global roadheader product spectrum. This equipment is named Tianyue, with a total length of 87 meters and a total weight of about 900 tons. It was jointly built by China Railway Construction Heavy Industry, State Grid Xinyuan Hunan Pingjiang Pumped Storage Company, and China Hydropower Eighth Bureau. It will participate in key energy projects in Hunan Province— —Construction of diversion inclined shaft project of State Grid Xinyuan Hunan Pingjiang Pumped Storage Power Station. Edit/Ma Xue
