The 49,400-pound SK210 excavator from Kobelco Construction Machinery USA is powered by a 160 hp Tier 4 Final Hino engine for fuel efficiency during heavy-duty operation. It delivers a digging force of 29,330 ft-lbs. In H mode, it has a 7 percent increase in work volume. In S mode, it provides up to a 10 percent increase in fuel economy. Eco mode adds another 6 percent increase in fuel economy. Efficiency comes from a new hydraulic regeneration system, which aids the arm by reusing force generated by the boom. A higher boom-foot cross section, thicker arm-foot base plate and stronger foot bases provide power to lift heavy loads and work safely. 281/888-8430; www.kobelco-usa.com.
