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.
Product Characteristics
· NTR450 is equipped with electric, hydraulic system and independent circuiting cooling system.
· 1.2m retractable cutting arm provides 8 maximum cutting range of 76m².
· Digital parameter design, optimized picking arrangement, precise matching of power cutput and propulsion, thus ensuring the excellent performance and stability.
· Double cutting speed design of 37/25min, The speed can smoothly switched between high and low according to rock hardness, reducing pick consumption and improving cutting efficiency.
· Equipped with a large 1500m³/min air volume airborn dust removal system to effectively handle the dust generated by cutting
· The lift fully enclosed air coordinating cab can effectively expand the vision or the operator and basically eliminate the blind are of operation.
· Optional soft and hard rock double cutting head configuration according to working conditions.
· Optima drill anchor assembly to improve machine adaptability
