What size concrete breaker do I need?
When working in hard material we recommend a 7,500 – 10,000-ft.lb. breaker, and if high production is critical, a 13,500-ft.lb. breaker would be beneficial. BREAKING CONCRETE: When breaking Concrete, the breaker is expected to penetrate the material, allowing it to crack and shake loose from the reinforcing steel.
How much does a rock breaker weight?

Are hydraulic hammers hard on excavators?
Hydraulic breakers are demanding on compact loader and excavator hydraulic systems, which is why some manufacturers recommend that routine hydraulic system maintenance is cut in half when breakers are used on these carriers.
How does a Rockbreaker work?
The upper force is greater than the down force and the valve spool is moved upwards. As the valve spool is rising and the oils passage is getting opened, the nitrogen gas pressures down the piston. The whole pressure is transmitted to the tool (also known as a chisel), which uses the hammering energy to break rocks.
