Doosan’s new DXB260H is a 5,400-pound breaker designed to be used with excavators in the 27- to 37-metric ton weight range. Rated in the 8,000 foot-pound impact energy class, the unit requires a hydraulic flow rate of between 39.5 and 66 gallons per minute. Tight tolerances in the manufacture of pistons and cylinders on the DXB260H eliminate leaks and jamming and guarantee full interchangeability of replacement parts, the maker says. www.doosanequipment.com
