Tunnel boring machine XCMG XTR4/230

TUNNEL MINING MINERS XCMG XTR series

XCMG Roadheader for tunneling

XCMG XTR series roadheaders have high cutting performance of various rocks. These flexible miners with optimal transverse or longitudinal actuators can be used for most tunneling operations. They can also be used to restore existing tunnels.

XCMG XTR roadheaders let you focus on what matters most: hassle-free, efficient demolition. Combines are designed for continuous rock excavation without blasting, which causes unwanted ground vibrations.

The XCMG XTR series tunnel boring machine is characterized by its flexible use for mechanized tunneling in hard and abrasive rock conditions. The robust, actuated and stabilized boom delivers perfectly matched cutting power, maintaining high productivity, excellent energy efficiency and, as a result, low operating costs.

Advantages

Economical rock removal to minimize operating costs
Optimal cutting performance thanks to telescopic boom with cutters and hydraulic stabilization
Effective dust suppression and cooling of cutter cutters thanks to the irrigation system
Fast assembly and disassembly and easy maintenance thanks to modular design
