Description

The crawler drilling rig is designed for drilling geophysical and structural exploration wells for oil and gas, exploration of solid minerals, building materials and groundwater, engineering and geological surveys, as well as drilling water intake and blast wells.
Drilling is performed by a rotational method with washing or purging of the well or augers. 
Moving along the mast rotator with hydraulic drive in conjunction with a special Elevator is used for screwing and unscrewing drill pipes and perform lifting operations.
The tripping and flow of the drilling tool in the bottom hole are produced by using hydraulic flow and provides optimum pressure on the face, including when drilling with air hammers and enables highly efficient drilling in rocks of any fortress.
Manage the installation tool is hydroficated and is carried out with the remote control. Serve the drilling rig two people. The unit is mounted on the frame of the skidder TT-4M or T-147.00 and is driven by its diesel engine.
