Description
Excellent for mass excavating, trenching, or fine grading, Komatsu's 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.
Overview
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.
