With a power booster feature, the 13 models in the RX line of hydraulic breakers achieve high breaking performance in tough applications without requiring additional hydraulic input. While the impact energy remains constant, the breaker increases blow frequency, resulting in enhanced percussive performance. A power stop function reduces blank firing, protecting the breaker and carrier while increasing the life of the components. Additional standard features on the hydraulic breaker line include hybrid technology (gas/oil), effective noise and vibration damping, and a highly efficiently internal control valve.
