Drilling rig URB-210

Designed for:
- Hydrogeological, industrial water well drilling
- Drilling for water depression wells, ventilation bore-holes, bumping wells, energy wells, freezing wells 
- Geological exploration

Applied drilling technologies:
- Rotary drilling with direct water circulation
- Rotary with reverce water circulation drilling (air lift technology)

Technical specifications:
1-st Rotary head type:
- hydraulic with the right side of the well's axis diversion possibility by the hydraulic cylinder operated from the driller's control panel
- hydraulic with rotation in forward direction from the drilling axis up to the 90 degrees angle, which makes safe and rapid hoisting possible during the rig's assembled/disassembled process
2-nd Rotary head type:
- hydraulic with a side diversion by hidraulic cilinder;
- all of unit's operating elements are hydraulically driven. Because of that additional technological equipments supplying without significant construction design changes is possible. Depending on the rig purpose application could be supplying by drilling rotary heads (technical characteristics could be diffrent from the presented); different hoisting equipments (pipe's rotation/clamp equipments depending from the using diameter). Operational labour intencity decreases in comparison with the mechanical transmission driven drilling rigs;
- hydraulic system operation provides the exact drilling tuning and operational control;
- the driller's workplace is organized on a hinged platform, fixed on the rear side ot the platform rig;
- for the DTH drilling implementation in hard geological-technical conditions rigs could be supplying of lubricator for the immersible DTH machinery;
- wide range of the accessories avalible on request provides the basic operations with the different types of the drilling toos and additional operations mechanisation.
