Rotary Drilling rig URB-25

The URB-25 drilling rig is designed for drilling and repairing industrial water supply wells, as well as for constructing technical wells, including degassing, ventilation, dewatering wells and wells for laying communications in underground mine workings, wells for hydraulic mining and underground leaching. The URB-25 is a lightweight and simplified version of the URB-40 rotary drilling rig. Due to the use of structural elements from the URB-40 drilling rig in the basis of the URB-25 drilling rig, the URB-25 has improved characteristics, greater operating efficiency in comparison with rotary rigs of the URB-3A3 (1BA-15) type. The URB-25 can be installed on cars, 3-axle tractor trailers (the rig is driven by a deck diesel engine with a capacity of 169 kW), trailers and other vehicles at the request of the customer. The drilling technologies used are: - rotary coreless drilling with flushing; - rotary drilling with direct flushing by a ring face; - rotary drilling with reverse flushing (AIRLIFT);
