Product Overview

Product Overview

Accurate: Full computer control drilling system, automatic positioning and drilling, accurate control of the angle and hole depth of the propulsion beam, small amount of over-excavation;

Safe: Only 3 people are required to operate a device, workers are far away from the tunnel face, which makes the construction safer. 

Efficient: Automatic drilling, automatic sticking prevention and fast speed of single hole drilling improve the construction progress;

Stable: Rock drills, main hydraulic components and chassis transmission systems are all adopted with imported well-known brands. 

Humanized: Fully enclosed cab with humanized design for operation to reduce noise and dust injury;
