Experience unmatched accuracy from the first to the last pass with the stable and productive PC290LCi-11, the 5th intelligent machine control excavator in the Komatsu family. Utilizing proven technology, it minimizes over-excavation and ensures a clean and accurately graded surface, eliminating the need for transportation permits common with larger machines.
- Large high-strength steel castings on the boom, arm, and bucket link.
- Closed-center load-sensing hydraulics for precise, fine control.
- Large displacement high-efficiency pumps provide optimal attachment flow.
- Large, spacious, quiet cab featuring a standard air suspension seat.
Product Features and benefits:
- Adjusts to Operator’s Experience: The excavator’s Intelligent Machine Control (IMC) system is designed to adapt to the operator’s experience level. The fully integrated grade assist feature automatically traces the target surface, minimizing over-digging. Additionally, a built-in facing angle compass ensures proper alignment with the target surface.
- Auto Stop Control: The machine is equipped with an auto stop control feature, which helps prevent potential damage during boom or bucket operation. When the bucket edge reaches the design surface, the machine automatically stops, enhancing safety and protecting equipment.
- Minimum Distance Control: IMC controls the bucket by automatically selecting the point closest to the target surface. This minimizes operator input while providing higher accuracy and confidence in grading. It streamlines the operation, making it more efficient.
- Critical Precision for Utility Applications: Specifically tailored for utility applications, the excavator allows operators to input structure details, invert elevations of pipe runs, and automatically calculates the fall of the pipe. This ensures critical precision in utility-related tasks.
- Powerful, Advanced Engine: The excavator is equipped with a powerful and environmentally friendly Tier 4 Final certified Komatsu SAA6D107E-3 engine. The engine features an integrated diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger, and a selective catalytic reduction system.
- Stroke Sensing Hydraulic Cylinder: The stroke sensing hydraulic cylinders provide real-time position feedback immediately displayed to the operator. This is an improvement over conventional aftermarket machine guidance systems, offering stability without requiring time to stabilize.
- Robust Undercarriage: The excavator features a robust undercarriage with a large counterweight and sturdy components, providing outstanding stability, especially in challenging working conditions.
