 Medium Hydraulic Breakers
Constant impact energy whatever the oil flow rate
The Medium Breakers are powered by a combination of oil and gas (Nitrogen). 70% of the impact
energy is generated by gas power, which means that the breakers run independent of the carriers
hydraulic supply.
Simple design for high reliability and low maintenance
There are only three moving parts:- the percussion piston
- the control valve
- the pilot valve
Routine maintenance take only a matter of minutes.
