The Doosan DXB260H hydraulic breaker features two-speed control of breaker frequency for improved efficiency in demanding demolition and rock-breaking applications. Delivering up to 600 blows per minute, the 5,400-lb. DXB260H is designed for use with excavators in the 27-to-37-metric-ton weight range, specifically the Doosan DX300LC and DX350LC. Rated in the 8,000 ft.-lb. impact energy class, the DXB260H requires a hydraulic flow rate of between 39.5 and 63.5 gal/min. The breaker’s suspension system extends excavator workgroup life by absorbing harmful vibrations and stress waves. Also, a patented main valve design reduces hydraulic pressure peaks that can reduce pump life, crack excavator workgroup welds and cause system overheating. Finally, an energy recovery system increases strike power by using energy generated by piston rebound. Standard features include a cradle-mounted grease station, blank fire protection, a mounting cap, auxiliary hydraulic hoses, two moil points, toolbox and a nitrogen checking device. In addition to the general purpose moil, tools available for the DXB260H include a blunt tool, a chisel and a pyramidal or “nail” tool.
