Design, Test and Evaluate

The mantra behind the design has been to test and evaluate; this has led to the RH460 design being able to prolong hammer life and increase drilling penetration rates. At its core is the ability of the RH460 to utilize an enhanced air cycle, which leads to a reduction in fuel consumption. Furthermore, power levels improve productivity through better lubrication capabilities and increased resistance against galling; all combined with developments in the piston bearing design. Put quite simply; piston and hammer life are dramatically increased.
