Water Well Borehole Portable Pneumatic Diesel Crawler Mounted Drill Rig
Water Well Borehole Portable Pneumatic Diesel Drilling Crawler Machine Rigs
Introduction of ST350 pneumatic drilling rig
The ST350 pneumatic DTH drilling rig is capable of drilling up to 325mm diameter holes for pore-forming purposes to a depth of 350 meters.
ST350 new generation multi-purpose DTH deep water well drilling rig is our independent research and development products. These new generation DTH are coupled to higher air power, and thus play a significant role in leading to faster drilling rates.
Adopting newest model & advanced hydro technology, our water well drilling machine are mainly used for well drilling in resource exploration and hydrology wells, civil use water well, agriculture irrigation project, and can also be used for coal-mine gas exploitation, coalbed methane, shallow
