Strong impact energy.
Quick & easy back up the parts in the market as this style of breaker is most common & all the parts are interchangeable.
Features may include:
Auto-Stop- Automatically stops operation of breaker when object is broken which protects damage to parts and extends the life time of breaker
- Less stress to hydraulic components as absorbing pressure fluctuation
- Increases efficiency by replenishing short oil flow
- Used anti-abrasion steel
- Longer life by high quality material
- Minimize the impact caused by blank fire.
- Safe from abnormal wearing
- Higher impact power with long stroke
- Absorbs repercussion from hammering and increases camier endurance
- Ensures higher impact power
- Maximize productivity from variable speed control (D&A 70V-550V)
- Internal control valve system is more efficient by 10% to 15% than other breaker's valve, stays cooler and makes the quicker and harder-hitting
- Avaliable to install auto-Lubrication or centralize lubrication kit (over D&A 100V-550V)
