Excellent for mass excavating, trenching, or fine grading, our largest intelligent machine excavator can increase your productivity and efficiency without the worry of over-excavation from first to last pass, straight to grade. The PC490LCi-11 is designed for heavy construction, quarrying and demolition applications, delivering high productivity and lower owning and operating costs. Key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

    Features and benefits

    Adjusts to the operator's experience level

    Adjusts to the operator's experience level

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

    Auto stop control

    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.

    Comfortable working space

    The wide spacious cab includes a heated air suspension seat with reclining backrest. The seat height and position are easily adjusted using a pull-up lever. The armrest position is easily adjusted together with the console. Reclining the seat further enables it to be fully laid back with the headrest attached.
