Hydraulic Breaker - Doosan

The Doosan DXB170H hydraulic breaker features nitrogen gas-assisted operation for improved efficiency in demanding demolition and rock-breaking applications.  The 3,572-lb. DXB170H delivers up to 600 blows per minute and is designed for use with excavators in the popular 18- to 28-metric-ton weight range. Rated in the 5,000 ft.-lb. impact energy class, the DXB170H requires a hydraulic flow rate of between 26.5 and 39.5 gal. per minute. An energy recovery system on the DXB170H increases strike power by using energy generated by piston rebound. Also, a patented main valve design reduces hydraulic pressure peaks that can reduce pump life, crack boom welds and cause system overheating. Finally, the breaker’s suspension system extends boom life by absorbing harmful vibrations and stress waves.
