Inquire Now
• Rock drill: hydraulic rock drill is designed with 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: high-efficiency low-discharge engine, articulated frame, full-driven adaptive walk system, good vehicle manoeuvrability, and good trafficability.
• Drill arm: the proprietary technology is used for full-sided parallel holding of the drill arm, with accurate positioning; the drill arm is designed with the interlocked telescopic structure, capable of effectively enlarging the rock drilling range.
• Drilling system: designed with the automatic rod jamming, idle drilling prevention and automatic rod retrieval functions, capable of effectively improving the drilling efficiency.
