Tunnel Roadheader Machine for Coal Mine

Tunnel Roadheader Machine for Coal Mine

NTR450 Road Header is a kind of mechanized heavy-duty and efficient tunneling equipment used for tunnel excavation, which can be used for large-section highway, railway and other tunnel excavation construction projects with an altitude of over 3,500 meters.
The need to understand the rock cutting process in an intensive way has become more and more of a necessity due to the various options using mechanized excavation and tunneling methods. The selection of the right rock cutting and excavation method is the starting point for every project and determines the project’s success or failure. Over the last decade, major changes have occurred not only in the development, but also with the technology of rock cutting via roadheaders and rock cutting attachments. The new engine provides up to a 90 per cent reduction. The tunneling roadheaders utilizes a new carrier which uses more efficient hydraulic and water systems.
