Overhead, underground

The Redbore 30 boxhole drill has a clear mission. It is searching for veins of ore that cannot be accessed without costly development. What’s so special about this concept? It works overhead, drilling upward into the back. This is the first Direct Drive designed by J. S. Redpath for this specific application. The choice fell to the compact Hägglunds direct drive hydraulic motor from Rexroth. It occupies minimum volume since it has no gear reduction, couplings and foundations, which would require additional space. In addition the motor is very robust and not sensitive to the high shock loads.
