China Railway Engineering Equipment Group Co., Ltd.

Earth Pressure Balance Shield Machine is core mechanized tunnelling equipment that cuts soil or rock with a rotating cutterhead, removes muck by screw conveyor or slurry circuit and erects segments simultaneously, delivering integrated excavation and support for metro, railway, road, municipal and water-conveyance tunnels.

• mechanized tunnelling for metro, railway, road and municipal tunnels

Slurry Balance Shield Machine is core mechanized tunnelling equipment that cuts soil or rock with a rotating cutterhead, removes muck by screw conveyor or slurry circuit and erects segments simultaneously, delivering integrated excavation and support for metro, railway, road, municipal and water-conveyance tunnels.

• mechanized tunnelling for metro, railway, road and municipal tunnels

Open Hard Rock TBM provides full-face mechanized excavation for hard-rock and complex-geology tunnels, relying on heavy disc cutters and high-thrust systems for continuous rock breaking, support and mucking in railway mountain tunnels, water-conveyance projects, pumped-storage schemes and mine roadways.

• mountain tunnels, water-conveyance projects, pumped storage and mine roadway excavation

Dual-Mode Shield Machine is core mechanized tunnelling equipment that cuts soil or rock with a rotating cutterhead, removes muck by screw conveyor or slurry circuit and erects segments simultaneously, delivering integrated excavation and support for metro, railway, road, municipal and water-conveyance tunnels.

• mechanized tunnelling for metro, railway, road and municipal tunnels

Rectangular Shield and Rectangular Pipe Jacking Machine serves mechanized excavation of non-circular and rectangular sections. Multi-cutterhead layouts deliver high space utilization with low disturbance to surroundings, ideal for underpasses beneath existing roads, mining-and-excavation metro stations, utility corridors and shallow municipal tunnels.

• underpasses beneath existing roads, mined metro stations, utility corridors and municipal tunnels

Vertical Shaft Boring Machine provides full-face mechanized excavation for hard-rock and complex-geology tunnels, relying on heavy disc cutters and high-thrust systems for continuous rock breaking, support and mucking in railway mountain tunnels, water-conveyance projects, pumped-storage schemes and mine roadways.

• mountain tunnels, water-conveyance projects, pumped storage and mine roadway excavation

Inclined Shaft TBM provides full-face mechanized excavation for hard-rock and complex-geology tunnels, relying on heavy disc cutters and high-thrust systems for continuous rock breaking, support and mucking in railway mountain tunnels, water-conveyance projects, pumped-storage schemes and mine roadways.
