piroc MB and HB hydraulic breakers are built for medium and heavy excavators from 10 to 140 tonnes. The MB range is designed for concrete and asphalt demolition, secondary rock breaking and primary rock excavation on construction sites. The HB range takes on the toughest work: blast-free rock excavation, secondary breaking in quarries and mines, and demolition of massive reinforced concrete structures.
Both ranges feature smart control technology. AutoControl automatically adjusts the piston stroke to the material, and VibroSilenced Plus reduces noise and vibration. Automatic lubrication with ContiLube II comes as standard on every breaker. The result is more output from your machine, with less wear and less downtime.
Epiroc MB breakers are available for excavators from 10 to 32 tonnes, HB breakers from 22 to 140 tonnes.
Request a quoteThe nitrogen chamber acts as a gas spring and pushes the piston back after every blow. This puts the available hydraulic energy to more efficient use and delivers high impact energy and blow frequency without placing a heavier load on the excavator's hydraulic system.
The piston stroke adjusts automatically during operation. In soft material, the breaker uses short strokes at a high impact rate. In hard material, it switches to long strokes with maximum impact energy. You get the best performance in every material, without the operator having to change any settings.

On the MB range, StartSelect lets the operator choose how the breaker starts and stops. AutoStop prevents blank firing on solid ground, and AutoStart makes positioning on unstable ground easier. The HB range has IPS, which manages this automatically during operation. Both systems protect breaker and machine against unnecessary wear.
