Leave nothing behind

Expect first-to-last-pass accuracy in a stable and productive machine across multiple applications, without the transportation-permit headaches of bigger machines. The 5th intelligent machine control excavator in the Komatsu family, the PC290LCi-11 leverages proven technology that minimizes over-excavation and leaves nothing behind but a clean and accurate graded surface.

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 standard air suspension seat.

Features and benefits

Excavator_PC210LCi 11_literature link_Slope_ko_v1.psd

Adjusts to the operator’s experience level

A fully integrated grade assist automatically traces the target surface to minimize over digging. A built-in facing angle compass ensures the machine is aligned with the target surface.

Auto stop control

To help eliminate potential damage during boom or bucket operation, the machine automatically stops when the bucket edge reaches the design surface.

Minimum distance control

IMC controls the bucket by automatically selecting the point closest to the target surface, which minimizes operator input while providing higher accuracy and grading confidence.

Critical precision for utility applications

For utility customers looking for the utmost precision, the excavator allows your operator to input structure, invert elevations of pipe runs and automatically calculates fall of pipe.

Powerful, advanced engine

Your fleet can be environmentally friendly without sacrificing power. Excavators with IMC 1.0 are equipment with a Tier 4 Final certified Komatsu SAA6D107E-3 engine, which features an integrated diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger and selective Ccatalytic reduction system.

Stroke sensing hydraulic cylinder

Stroke sensing hydraulic cylinders provide real-time position that is immediately displayed to the operator. This is an improvement over conventional aftermarket machine guidance (indicate only) systems with tilt sensors that require time to stabilize.

Robust undercarriage

A large counterweight and robust undercarriage components help provide outstanding stability.
