KQ311 Hydraulic Scaling Rock Drill Rig
Request a Quote
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.
