The wait is over. Komatsu has released two larger intelligent Machine Control excavators—the PC360LCi-11 and PC490LCi-11. “Many of our customers have been asking us to scale iMC technology to a larger-sized excavator,” said Jason Anetsberger, Komatsu America senior product manager. “Whether you are mass excavating, trenching, or fine grading, the PC490LCi-11 will help increase productivity and efficiency while removing the burden and worry of over-excavation. All the operator has to worry about is keeping the bucket full. Komatsu delivers maximum productivity and accuracy, from first to last pass.” The Komatsu PC490i is the largest 3D, semi-automatic construction excavator on the market. Noting that the 36-ton class is the most popular size excavator for North American contractors, Anetsberger commented that “The PC360 is nimble, yet highly productive. From trenching on a utility worksite to mass excavating on a highway project, the PC360LCi-11 is flexible and versatile enough to be at home on any jobsite.” Komatsu’s iMC system—which utilizes sensors, stroke-sensing hydraulic cylinders and GNSS antennas— is fully integrated into the machine. The system uses 3D design data that is loaded into the monitor to accurately display the excavator’s position relative to the target grade. When the bucket reaches the target surface, auto- matic features kick in to prevent over-excavation. Anetsberger explained several features that enable these excavators to go Straight To Grade: • Auto Grade Assist: As the operator moves the arm, the boom automatically adjusts the bucket height, tracing the target surface and limiting over-digging. • Auto Stop Control: During boom and bucket operation, the equipment automatically stops when the bucket edge reaches the design surface, minimizing design surface damage. • Minimum Distance Control: The machine con- trols the bucket by automatically selecting the point on the bucket closest to the target surface. If the machine is not facing a sloped surface at a right angle, it will still follow the target surface and limit digging below it. The Komatsu PC490i is the largest 3D, semi-automatic construction excavator on the market. PRODUCT NEWS New Komatsu PC360LCi-11 and PC490LCi-11 Excavators: WHEN BIGGER REALLY IS BETTER 9
