Epiroc Hydraulic Attachments HB7000

Our features make the difference
We want to make our hydraulic breakers highly adaptable, durable, efficient and with best noise and vibration level. For your profitability, operator comfort and for the environment.

Energy Recovery
The piston recoil energy is automatically utilized to increase the performance without additional hydraulic input and to lower vibrations.

Intelligent Protection System (IPS)
IPS ensures that the hydraulic breaker always starts in the AutoStart mode. When the contact pressure between chisel and material increases and AutoControl switches from a short piston stroke to a long piston stroke IPS switches automatically to the AutoStop mode. When the chisel breaks through the material the breaker automatically shuts off and prevents blank firing.

PowerAdapt
Built-in overload protection valve shuts off the hydraulic breaker when operating pressure is not in line with specifications thus protecting it from costly downtimes and repairs.

VibroSilenced Plus
System insulates the percussion mechanism and breaker box by polyurethane damping and guiding elements and sealing of all breaker openings to reduce noise and vibration levels.

AutoControl
Automatic piston stroke length switching system adjusts the output balance during operation, thus optimizing the performance.

Retainer bars
Two oval-shaped tool retainer bars with a simple but reliable locking system - for quick tool exchange and increased durability.

Tie rods
Vibration damping tie rods with polyurethane collar and HeliCoil locking system for high durability

chamber ventilation
Active non-return valve ventilates the percussion chamber during the upwards movement of the piston minimizing penetration of abrasive dust and expelling dust contaminated grease

Hybrid technology
With an integrated nitrogen piston accumulator for constantly high impact energy, safe start-up and smooth operation
