XTR4/180 Tunnel Roadheader PRODUCT FEATURE

1. New cutting mechanism, conical table-shaped small diameter cutting head, double helix tooth picking, strong rock breaking ability.

2. Ultra-narrow body modular design, body width 1.7 meters.

3. Spray with airborne fan double dust removal, effectively improve the dust removal effect, reduce dust pollution.

4. The shipping mechanism adopts anti-card chain design to effectively avoid the phenomenon of card chain and chain jumping.

5. Air-cooled and water-cooled heat dissipation, good heat dissipation effect, in the absence of external water source, the host can move for a long distance.

6. The electrical system adopts international famous brand components, with advanced functions and high stability.

7. The hydraulic system adopts constant power, pressure cut-off and load sensitive control technology, which effectively improves the life of hydraulic components and reduces system failure. The main hydraulic components are adopted international famous brands.
