Crawler type deel hole drill adopts diesel motor(electric motor).Hydraulic oil pump unit offers power to hydraulic motor moving,turn-around,propulsion and lifting.and angle orientation of oil cylinder,etc.When drill is working,only the down-hole hammer consumes the compressed air.
The drill is used for water well,geothermic air-conditioner drilling operation and various stonework blast hole operation;the drill can also realize the process such as breast wall drilling with casing following,conduct drilling grouting hole of the hydropower cofferdam,grouting hole dyke seepage control and grouting hole for base enforcement and anchor hole,etc.
