PC290LCi-11

Komatsu is pleased to announce the latest arrival to the intelligent Machine Control family: the PC290LCi-11 intelligent Machine Control hydraulic excavator. Leveraging the proven excavator technology first introduced on the PC210LCi, the PC290LCi-11 is the 5th intelligent Machine Control excavator from Komatsu. Featuring factory integrated 3D GNSS technology, and improved machine control performance, the PC290LCi-11 empowers operators to dig straight to grade, faster. Minimizing over-excavation and bedding material, this machine leaves behind nothing but clean and accurate grade.

Features

intelligent Machine Control

Intelligent Machine Control excavator with semi-automatic control allows the operator to improve work efficiency as compared to conventional aftermarket machine guidance (indicate only) or manual operation. Rough digging to finish grading, intelligent Machine Control minimizes over-excavation to make every pass count.

Auto Grade Assist

With the auto grade assist function, the operator moves the arm, the boom adjusts the bucket height automatically, tracing the target surface and minimizing digging too deep. This allows the operator to perform rough digging without worrying about the design surface, and to perform fine digging by operating the arm lever only. The working range is expanded by holding the lever to move the boom downward.

Auto Stop Control

During boom or bucket operation, the work equipment automatically stops when the bucket edge reaches the design surface, thus minimizing damage to the design surface.

Minimum Distance Control

The intelligent Machine Control excavator controls the bucket by automatically selecting the point on the bucket closest to the target surface. Should the machine not be facing a sloped surface at a right angle, it will still follow the target surface and minimize digging below it.

Komatsu intelligent Machine Control Components

Standard factory installed intelligent Machine Control system for 3D GNSS machine guidance and semi-automatic control. Sensor package includes stroke sensing hydraulic cylinders, inertial measurement units, and GNSS antennas.

Stroke Sensing Hydraulic Cylinder

Sensor package with stroke sensing hydraulic cylinders provides real time position, immediately displayed to the operator. This is in contrast to conventional aftermarket machine guidance (indicate only) systems with tilt sensors that require time to stabilize.

Control Box

The monitor of the Komatsu intelligent Machine Control (control box) uses a large 12.1" (30.7 cm) touch screen for visibility and ease of use. The screen layout is customizable to display information in an easily understood fashion with a variety of views including 3D, plan, and section.

Facing Angle Compass

The orientation and color of the facing angle compass’s arrow shows the operator the facing angle of the bucket edge relative to the target surface. This allows the bucket edge to be accurately positioned square with the target surface, which is useful when finishing slopes.
