Komatsu Ltd. is the second largest global manufacturer and supplier of earth-moving equipment for the construction, surface and underground mining, and forestry industries, and its Rolling Meadows, Illinois-based subsidiary, Komatsu America Corp., just launched the new PC390LCi-11 hydraulic excavator. The new machine is a 3D semi-automatic excavator that was designed to be as fast and nimble as Komatsu’s 36-ton (32.6-tonne) machines, but with the stability of a much bigger excavator.

An Atypical Excavator

Komatsu designed the PC390LCi-11 to tackle a variety of applications that call for greater over-the-side lift capacity, from production excavating to utility trenching, site prep, and more. Komatsu knows how appreciated the PC210LCi-11’s factory-standard machine-control-enhanced joysticks are, and as a result they have included them on the new model to enhance operator comfort, control, and convenience.

Other standout features that are sure to make the PC390LCi-11 popular at the jobsite include an 8.85 liter, 257-horsepower, Tier 4 Final-complaint SAA6D114E-6 engine. To assist the operator, the excavator supports KOMTRAX level 5 technology, which reports fuel and diesel exhaust fluid levels, Komatsu Diesel Particulate Filter regeneration status, machine location, as well as cautions and maintenance alerts.

Fully Tech’ed Out

The Komatsu PC390LCi-11 also supports a number of assistive technologies, including Auto Grade Assist for automatically adjusting the bucket height, Auto Stop Control for preventing the bucket edge from encroaching on the design surface, Minimum Distance Control for minimizing digging below the target surface, and Facing Angle Compass to ensure the bucket edge is always square with the target surface. The Realistic 3D Display allows for rendering the machine and design surface in realistic detail, which helps the operator visualize the machine’s orientation relative to the features of the jobsite. And finally there’s Control Box, which consists of a 12.1-inch (307-millimeter) touchscreen with an icon-based interface for ease of use.

The PC390LCi-11 excavator includes a 3-year or 2,000-hour (whichever comes first) Komatsu CARE maintenance program. This covers scheduled factory maintenance, a 50-point inspection at each service, up to two complimentary Komatsu diesel particulate filter (DPF) exchanges, and up to two diesel exhaust fluid (DEF) tank flushes in the first five years.
