The rig is designed for drilling geophysical and structural exploration wells for oil and gas, prospecting for solid minerals, building materials and groundwater, geotechnical surveys, drilling water intake and blast holes. Drilling is performed in a rotary way with flushing or blowing the well or using augers.
The unit is mounted on the MTLB chassis and is powered by the car engine.
Drilling rig control is fully hydraulic and concentrated on the driller's console. The control panel contains control devices and regulators of the bottomhole force, feed and lift rates, as well as the rotation frequency of the rotator spindle. A distinctive feature of the unit in comparison with the standard URB 2A-2 is its lower weight and size, which allows it to be installed on a chassis with a lower carrying capacity.
