URB-2A-2 drilling rig on the chassis "Ural-4320" or "KamAZ-43114"

The URB-2A2 drilling rig is one of the most popular models in this range of drilling machines due to its reliability and versatility. URB-2A2 is designed for drilling geophysical and structural exploration wells, field exploration, engineering and geological surveys, construction wells, construction of water intake and blast wells at temperatures from -400 to +400 C. The URB-2A2 drilling rig is equipped with a movable rotary perform rotary drilling with flushing or bottom hole blowing, as well as drilling with augers. The hydraulic cylinder and the tackle system ensure the movement of the rotator along the mast, due to which drilling and extension of the drilling tool occurs. Together with the hydraulic jack, the rotator performs lowering, lifting and feeding of the drilling tool. The URB-2A2 unit can be equipped with two 4VU1-5 / 9 compressors, with a 4VU1-5 / 9 compressor and a NB-50 or NB-4 mud pump, or a KV- compressor station. 10 / 10S, KV-12 / 10S, KV-12 / 12S.
