The descriptions of the hydraulic air pneumatic deep well borehole drilling machine.
The hydraulic air pneumatic deep well borehole drilling machine is a type of deep water well drilling rig equipment, it is also a type of DTH water borehole drilling rig machine, it uses compressed air to drill and it can drill through rocks with ease. The hydraulic air pneumatic deep well borehole drilling machine can drill 580m into the earth and the drilling diameter is 140mm to 350mm, the recommended drilling pipe is Φ102mm Φ108mm Φ114mm. It is one of the most popular crawler deep borehole drilling machines in the market.
