Great Equipment & Exceptional Service

Rock drill: hydraulic rock drill is designed with a special structural process on the basis of the tunneling construction process in China, being characterized by super-strong deflection resistance capacity, high drilling speed and low drilling tool exhaustion, capable of effectively improving the use performance of the tunnel side hole operation.• Booster: lightweight high-strength alloy beam, high-strength, flexural resistant, torque resistant and fatigue performance, longer service life.

• Chassis: energy-efficient, environment-friendly and low-discharge engine with strong power, all-terrain, and full-driven adaptive walk system; whole vehicle frame, rear wheel steering, and good vehicle stability.

• Drill arm: the proprietary technology is used for the full-sided parallel holding of the drill arm, with accurate positioning; the drill arm is designed with equal strength, characterized by reasonable structure, high strength and long service life.

• Drilling system: designed with the automatic rod jamming, idle drilling prevention, and automatic rod retrieval functions, capable of effectively improving the drilling efficiency.
