marketplace | by Amy Materson AMaterson@randallreilly.com EDITO R PICK 'S BOOST BREAKER POWER A chieve increased strike power with the DXB130H and DXB190H breakers from Doosan, which feature an energy recovery system to boost productivity. Designed for use with 15- to 22-metric-ton excavators, such as the DX180LC, DX 190W and DX201W, the DXB130H delivers up to 600 blows per minute and is rated in the 3,000-foot-pound impact energy class, requiring a hydraulic flow rate between 23.8 and 37 gpm. The DXB190H, suitable for 21- to 31-metric-ton excavators such as the DX225LC, DX235LCR, DX255LC and DX300LC, requires between 31.7 and 47.5 gpm and is rated in the 6,000-foot-pound impact energy class. Both nitrogen powered breakers have an upper/lower suspension system that isolates the power unit from the housing, as well as standard blank-fire protection via a cushion of oil at the base of the piston. The breakers have a suspension system that absorbs vibration and stress waves, and a main valve design that reduces hydraulic pressure peaks to extend pump life while reducing overheating. The DXB190H also has two-speed control, enabling the operator to manually adjust the breaker frequency between low and high frequency settings, matching the breaker impact rate to the working conditions. TRAILER HAULS EMPTY CONTAINERS Haul empty 20-foot containers with Landoll's Model 342 light duty gooseneck trailer, which has a standard fifth wheel kingpin, 7-way electrical connector and single air brake axle. Suitable for short single-axle tractors, the 31-foot-long trailer has an 8-foot gooseneck with 23-foot lower deck and will handle 25-foot-long containers. The trailer operates hydraulically via a wet kit on the truck or with an optional 27-horsepower engine package. The 8,800-pound Model 342 has a 10.3-degree load angle, 15,000-pound air brake axle and features a gear box chain drive system with continuous 1/2 chain with 12,000 pounds line pull. Additional standard features include loading bridle, tie-down chains, push bar, container side pin lock-downs and storage box. EquipmentWorld.com | January 2013 15
