Drilling rigs are designed for drilling geophysical and structural/exploratory oil-and-gas wells, for exploring the deposits of solid minerals, construction materials, and groundwaters, for engineering and geological surveys, as well as for drilling water-intake and blast holes.
Drilling is done by rotation with subsequent washing or blowing of wells, or by means of augers.
Hydraulically-driven rotator moves along the mast and is used for drilling, for build-up of the drilling tool, as well as (when combined with a hydraulic jack) for lowering and lifting the tool and for feeding the tool when drilling. The rotator is moved along the mast by a hydraulic cylinder and a hoist system.
Rig controls are fully hydraulic; the rig is controlled from the operator's control unit.
