351 Crawler Pneumatic Drilling rig


351 Crawler Pneumatic Drilling rig





351 Crawler pneumatic drill rig (down-hole drill rig 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.
351 crawler pneumatic drill rig is mainly used in stonework drilling, such as water and electricity project, exploitation of open mine and road construction
