RD520 Rock Drill Rig 20kW 225kg
brief introduction
RD520 hydraulic rock drill is designed for use in mine development and drilling of the working face of driving carts. It is also suitable for bolt hole, exploration and injection hole drilling.
RD520 is a hydraulic impact rock drill with independent reversible rotation and low profile height. Known for its hydraulic efficiency and high permeability, the RD520 offers superior usability through its modular construction and visual wear indicator.
Robustness is achieved by having only a few pressurized seams between the functional modules. The drill is equipped with stabilizers to control the contact between the bit and the rock. The stabilizer also suppresses the recoil pulse of the rock and prolongs
the service life of the drill.
