Northern Heavy Industries shaft tunnel boring machine
Northern Heavy Industries independently developed its first borehole-expanding shaft shield machine for a pumped-storage power station project in Zhejiang Province. The machine features a conical cutterhead and employs a slag removal method with borehole expansion. 3D intelligent modeling, laser cutting, and robotic welding were employed in its development and manufacturing to ensure product quality and precision. This represents a new achievement in the cross-scenario application of shield machine technology.
