Rock drill, YN30E internal combustion rock drill, YN27C internal combustion gasoline rock drill, internal combustion rock drill 
 Feature 
 1, YN30E handheld internal combustion rock drill is made by a small gasoline engine, compressor, rock drill Trinity combination of hand-held drilling tool. 
 2, operating by itself to produce the compressed air blowing to wash the eyes of the rock powder gun. 
 Host weight only 30KG, easy to carry, suitable for alpine, no power, no region of the pressure equipment, greater mobility of temporary works is particularly suitable. 
 On the rocks perforated vertically downward, horizontal, up less than 45 °. Vertically down the deepest hole to a depth of 6m. 
 Use 
 1, the machine applies to the perforated rock, can be changed to a crusher and tamping machine to replace a few parts for a variety of broken shovel chisel, digging, splitting and tamping work. 
 2, whether in the mountains, plains; can work both in the heat of the +40 ° C or -40 ° C cold region. The machine has a wide range of adaptability.
