CL351 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.
CL351 crawler pneumatic drill is mainly used in stonework drilling,such as water and electricity project,exploitation of open mine and road construction.
