Komatsu PC360LCi-11, PC490LCi-11 Intelligent Excavators

May 26, 2016

The PC360LCi-11 and PC490LCi-11 excavators feature Intelligent Machine Control (IMC) technology that uses a “unique” sensor package, including stroke-sensing hydraulic cylinders, an Inertial Measurement Unit sensor, and GNSS antennas. The machines utilize 3D design data loaded into the in-cab monitor to accurately display machine position relative to target grade. When the bucket reaches the target surface, automation kicks in to limit over excavation.

The automated system includes a number of features, says Komatsu:

Auto Grade Assist—As the operator moves the arm, the boom adjusts the bucket height automatically, tracing the target surface and minimizing digging too deep.

Auto Stop Control—During boom and bucket operation, the work equipment automatically stops when the bucket edge reaches the design surface, thus minimizing design surface damage.

Minimum Distance Control—–The machine controls the bucket by automatically selecting the point on the bucket closest to the target surface. If the machine is not facing a sloped surface at a right angle, it will still follow the target surface and minimize digging below it.

Facing Angle Compass—The orientation of the facing-angle of the compass arrow shows the operator the facing angle, relative to target surface. This allows the bucket edge to be accurately positioned square with the target surface.

Realistic 3D Display—the machine and design surfaces are shown in realistic 3D.  The angle and magnification of the views can be changed, allowing the operator to select the optimum view, depending on work conditions.

Control Box—The Intelligent Machine Control monitor uses a large 12.1-inch screen for visibility and ease of use. A touch screen icon interface, instead of a multi-step menu, simplifies operation.
