Details
RDA351(ALTAS CM351 TECHNOLOGY) crawler pneumatic drill (down-hole drill with high blast pressure) totally utilizes compressed air as its power. It is equipped with pneumatic motor with high power, the heavy-duty hydraulic drill arm and the key parts are all imported, which guarantee the reliable quality of the drill, especially realize much less energy consumption of rolling fraction than that of sliding fraction and make the wear of sliding framework be lower.
