NTR450 Tunneling Roadheader

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.


Product Characteristics

1.NTR450 is equipped with  electric, hydraulic system and independent circuiting cooling system.

2.1.2m  retractable cutting arm provides 8 maximum cutting range of  76m².

3.Digital parameter design, optimized picking arangement, precisematching of power cutput and propulsion thus ensuring the excellent performance  and stablity.

4.Double cutting speed design of 37/25min, The speed can smoothly.switched between high and low according to rock hardness, reducing pickconsumption and improving cutting efficiency.

5.Equipped with a large 1500m³/min air volume dust removalsystem to effectively handle the dust generated by cutting.

6.The lift fully enclosed air coodinating cab can effectively expand the visionor the operator and basically eliminate the blind are of operation.  

7.Optional soft and hard rock double cutting head configuration According to working conditions.

8.Optional drlll anchor assembly to improve machine adaptability.
