The 68,100-pound SK300LC-10 excavator from KOBELCO is powered by a 252 hp Tier 4 Final HINO engine, enabling it to tackle heavy-duty applications. Its engine incorporates a selective catalytic reduction system with diesel particulate filters, which converts NOx into harmless nitrogen and water emissions; the dual system ultimately minimizes diesel exhaust fluid and decreases NOx emissions by 88 percent, while providing low operation costs. It delivers a digging force of 37,300 ft-lbs, while minimizing fuel consumption. Its hydraulic regeneration system aids the arm by reusing force generated by the boom to further minimize energy loss and ensure performance. A higher boom foot cross-section, thicker arm-foot base plate and stronger foot bases are provided for added reinforcement. A redesigned boss shape and boom foot improve overall stability while evenly distributing digging forces for durability. 281/888-8430; www.kobelco-usa.com
