Excavator Uses 3D Design Data for More Precision
Komatsu augmented its intelligent Machine Control lineup with the addition of the new PC290LCi-11 that provides first-to-last-pass accuracy. Like its predecessors, the excavator features Komatsu’s unique sensor package – stroke-sensing hydraulic cylinders, an inertial measurement unit sensor and global navigation satellite system antennas – that utilizes 3D design data to accurately check its position against the target elevation and semi-automatically limit overexcavation.
“The PC290LCi-11 is perfect for applications where customers are looking for good stability and working range. It has a 30-ton-class undercarriage and an upper structure similar to our standard PC240LC model. This excavator also includes a 3.2-meter (10.49-foot) arm,” said Andrew Earing, Senior Product Manager, Tracked Equipment, noting that a 3.5-meter arm option will be available soon. “Its size helps to avoid most transportation limits associated with larger size-class excavators, making it a good fit for residential and utility work, as well as smaller nonresidential jobs.”

The machine and design surface are shown in a realistic 3D format. The angle and magnification of the views can be changed, allowing the operator to select the best option, depending on working conditions.
Easily Switch Modes, Offset Functions, More Precision
Operators can choose between manual and semi-automatic modes, as well as design offset functions using switches on the joysticks. The semi-automatic mode features Auto Grade Assist. As the operator moves the arm, the boom adjusts the bucket height to trace the target surface and minimize the chance of digging too deep.
Additionally, the PC290LCi has Auto Stop Control that halts the working equipment when the bucket edge reaches the design surface, which reduces design surface damage. Minimum Distance Control regulates the bucket by automatically selecting the point on the bucket closest to the target surface. Finally, the Facing Angle Compass shows the operator the facing angle relative to the target surface, allowing the bucket edge to be accurately positioned square to the target surface.
“Komatsu introduced intelligent Machine Control excavators four years ago with the PC210LCi, which is now in its second generation with the dash-11 model,” said Earing. “As we continued to expand our intelligent product line, we heard customers asking for a PC290LCi. With the introduction of this model, we are pleased to demonstrate our commitment to our customers.”
Excavator Covered by Komatsu CARE
The PC290LCi-11 has Komatsu’s KOMTRAX Level 5 technology that provides machine data such as fuel and diesel exhaust fluid (DEF) levels, Komatsu Diesel Particulate Filter (KDPF) regeneration status, machine location, cautions and maintenance alert information.
Whether rented, leased or purchased, the PC290LCi-11 is covered by Komatsu CARE, complimentary for the first three years or 2,000 hours. It includes scheduled factory maintenance, a 50-point inspection at each service interval and up to two complimentary KDPF exchanges and two DEF tank flushes in the first five years.
