The extreme requirements for drilling in mines and tunnels require the highest quality and reliability.
The reliability of the full-face drilling machine, the shaft drilling machine, Deep hole drilling and tunnel boring machine is mainly dependent on the used hydraulic system. The Hydro Space Research in Mining Equipments has developed new hydraulic valves for extreme applications, under a holistic view of the physical, technological, tribological and functional aspects.
In addition to security, reliability, availability and performance are added other priorities such as energy efficiency and environmental protection.
