Designed for drilling holes up to 16m deep in hard coal and soft shale using typical spiral drill rods up to 48mm in diameter. The driving element of the drills is a hydraulic satellite motor of the SMW type adapted to be supplied with oil water emulsion of the HFA type coming from emulsion hydraulic buses of mechanized casings. Oil supply from other hydraulic power sources is also possible. An additional design element is a simple percussion mechanism to facilitate drilling in hard materials. In addition, the HWGU/SMW Hydraulic Mining Drillers are equipped with a slotted filter to eliminate larger dirt from the feed medium.
The detailed design of the equipment is the result of direct long-term cooperation with the end users of such tools. The use of a steering wheel with a double-sided handle with optimum spacing, a shielded control system, a built-in filtration system and a low noise level (77dB(A)) make the tools ergonomic, functional and safe to use.
