Main Applications

It's mainly applicable for the tunneling operations of metal mines and diversified underground roadways and tunnels (Such as electricity and water utilities). 

Maximum operation area coverage: 35m2.

Technical Features

Drill jambo

The hydraulic drill jambo adopts special structural process on the basis of the domestic 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. 

Propeller 

The lightweight high-strength alloy girder features high anti-bending, anti-distortion, and anti-fatigue performances and longer life.  

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. 

Drilling system

The three-stage anti-seizure, anti-empty-drilling, and automatic return functions of drilling tool are provided to effectively improve the drilling efficiency and reduce the consumption of drilling tool. 

Hydraulic system

The electronic control design is applied for the auxiliary motions, including outriggers and roof lamp to simplify the pipelines and ease the maintenances.  

Electric system

The electric parts of world’s renowned brands, including Schneider, Siemens, Phoenix, Littelfuse, and Williams, are applied to realize high reliability and long service life. The production and warning functions, including grounding malfunction protection, phase sequence protection, digital current/voltage indicator, drill jambo impact timer, oil return filter blockage warning, motor thermistor protection, motor overload protection, engine malfunction warning, and transmission malfunction warning, are provided.
