Hydraulic drills are intended to make geological-exploratory, methane drainage and protection boreholes in rocks of various hardness by means of a rotary drilling head supplied by a hydraulic unit. Power of the hydraulic unit supplying the drill is between 45 and 90 kW. Parameters of the unit are adapted to the drill applied and they meet customer expectations regarding any additional equipment to be likely supplied from it, e.g. mud pump, rope winch etc.
Through the modular design and structure, the drills may be configured to meet the customer’s demands. A frame the drill is mounted on, may be provided with cylinders enabling adjustment of the setting angle in vertical and horizontal plane. The drills are capable to drill boreholes both from 0 to +90˚ and from 0 to -90˚.
