Mine Tunneling Jumbo Drills with Double Arm

Mine Tunneling Jumbo Drills with Double Arm

Drilling and blasting remains one of the most important tunneling methods, with technology dominating this market segment. Tunneling jumbo is rolling out new drilling hardware in the shape of its sophisticated and powerful tunneling jumbo, which is also said to be productive and versatile. The machine is fully automated and runs on a new articulated carrier, fitted with a new cabin that has more visibility than previous designs, as well as low working noise.

• 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.
