Main Applications
It's mainly applicable for the tunneling operations of roadways and tunnels in mines and other underground projects.
Capable of drilling of blast holes, anchor rod holes, and undermining holes and installation of explosives, anchor rods, and air ducts. 
Maximum operation area coverage:72 square meters. 

Technical Features
1. Drill jambo
The hydraulic drill jambo adopts special structural process on the basis of the Chinese tunneling process to realize super-strong anti-bending capability, high drilling speed, and low drilling tool consumption and effectively improve the working performance of tunnel side hole drilling. 
2. Propeller 
The lightweight high-strength alloy girder features high anti-bending, anti-distortion, and anti-fatigue performances and longer life.  
3. Chassis
It's applied with energy-saving, environmental-friendly, and low emission engine, powerful all-road all-drive self-adaptive traveling system, integral frame, and rear-wheel steering system, featuring high vehicle stability. 
4. Drill boom 
The all-directional paralleling-maintained drill booms of proprietary technology features accurate positioning. The drill booms adopt equal-strength structure design to realize reasonable structure, high strength, and long life. 
5. Drilling system 
The automatic anti-seizure, anti-empty-drilling, and automatic return functions of drilling tool are provided to effectively improve the drilling efficiency.
