Doosan: DXB260H

By |  August 6, 2013

The Doosan DXB260H hydraulic breaker features two-speed control of breaker frequency for improved efficiency in 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 range. Rated in the 8,000 ft.-lb. impact energy class, the DXB260H requires a hydraulic flow rate of between 39.5 and 63.5 gallons per minute. With two speeds, the breaker frequency can be easily adjusted between short and long stroke settings. This allows the operator to match the breaker frequency to the ground conditions for optimized productivity. Standard features include a cradle-mounted grease station and blank fire protection. The breaker’s suspension system extends excavator work group life by absorbing harmful vibrations and stress waves. Also, a main valve design reduces hydraulic pressure peaks that can reduce pump life, crack excavator workgroup welds and cause system overheating.
