Following the release of four intelligent Machine Control (iMC) crawler dozers, Komatsu has now introduced its first intelligent Machine Control excavator, the PC210LCi-10.
Komatsu says that because of the machine’s exclusive control function, the PC210LCi-10 goes beyond simple guidance systems to semi-automatically limit over-excavation and trace a target surface. The control function also semi-automatically follows the design surface allowing for accurate finish grading, with real-time bucket edge positioning in relation to the machine and the job surface.
The company’s factory-installed iMC system, developed in partnership with Topcon, includes GNSS antennas, and stroke-sensing hydraulic cylinders for the boom, arm and bucket, plus an Inertial Measurement Unit for the real-time bucket edge positioning. Status is instantly displayed on the full color, multi-function 12.1-inch control box monitor, eliminating the wait time associated with conventional sensors, according to Komatsu. The iMC technology controls the boom, arm and bucket by checking position data from the bucket teeth using GNSS antenna and base station. It has three key features:
Auto grade assist allows the operator to move the arm, and the boom automatically adjusts the bucket height and traces the target surface. Fine digging can be done with the arm lever only, Komatsu says.
Auto stop control automatically stops the boom or bucket operation when the bucket edge reaches the design surface.
Minimum distance control automatically controls the bucket by selecting the point on the bucket closest to the target surface.
The 158-horsepower PC210LCi-10 has an operating weight of 52,036 pounds, and is powered by a Tier 4-Interim Komatsu SAA6D107E-2 engine.
