Our KQ311 hydraulic rock drill is powered by diesel engine and is mainly suitable for scaling operations in tunnels and caves of metal mines and various underground projects. The folding arm is fitted with a hydraulic hammer and translation mechanism driven by the rotating oil cylinder. It is capable of all-around operation thanks to the working surface, top plate, side wall and base plate. Meanwhile, the proportion pilot control is applied to the hydraulic system, making it flexible and smooth. The equipment can considerably improve the scaling efficiency and operational safety based on the compact structure, excellent mobility, small turning radius, and powerful climbing capacity.
- Equipped new Cummins QSB3.9-C80-31 Engine, inproved the standards for emissions and environment.
- Stable performance and high working efficiency.
- Safe travelling system, easy to move.
- Powerful and reliable engine
- The machine is small and easy to operate
- Suitable for water wells of different diameters, widely used in construction and agriculture.
