Precision and energy-efficient back head
Structure more concise , guarantee the pressure of Nitrogen ,reducing the volume of back head to make hydraulic breaker more energy-efficient.
Accumulator
To reduce the irregular pulse pressure in the hydraulic circuit pipe,so increase the strick power that make more powerful hydraulic breaker .
Long life piston
Increase piston’s stroke in order to improve hitting power
Special shock mitigation system to reduce recoil force,protect cylinder
The long service life due to applied heat treatment.
Main body
After six surface forging, the density of main body is much stronger and it’s hard to deformation
Good quality chisels
Use good material and special heat treatment
Through bolt
High strength screw design to ensure much longer life usage
