Kobelco Construction Machinery USA has introduced one new short rear swing excavator, the new SK270SRLC-5, and has announced updates on its SK230SRLC-5 model.
The 21-foot-9-inch dig depth SK270 has a digging force of 31,700 pounds and a maximum digging reach of 32 feet, 3 inches. While working in ECO-mode, Kobelco says the machine offers up to a 27 percent decrease in fuel consumption; while in H-mode, it gains up to a 7 percent increase in work volume per hour. It has a digging force of 31,700 pounds.
The SK230 has a digging depth of 21 feet, 7 inches and a maximum digging reach of 31 feet, 10 inches. According to Kobelco, the unit can see up to 31 percent in fuel efficiency, while gaining up to 8 percent in work volume per hour in either ECO-mode or H-mode.
Both machines have Kobelco’s intelligent control system, which allows smooth engagement and disengagement of machine functions. The power boost function instantly delivers up to 10 percent additional power with no time limit for extra digging capability. Heavy lift can be engaged when requiring extra lift capacity. Independent travel allows the machines to move, lift and swing simultaneously without loss of power.
The units use a Tier 4 Final Hino engine, which features a high-pressure common rail fuel injection system and variable geometry turbocharger to reduce particulate matter. A large EGR cooler decreases NOx emissions by up to 80 percent. A double offset duct structure reduces noise.
The cabs have wide access doors, adjustable suspension seat, and rear and right side cameras.
