Intelligent Excavator: Updated Machine Controls

The PC210LCi-11 is the latest revision to Komatsu’s intelligent excavator line. The machine boasts integrated machine controls that ensure the excavator’s arm will work only within a preset excavation model. This approach can drastically reduce rework and removes the need for stakes or grade checkers. The GNSS-based machine-control system can be used for 2D or full 3D grade control and is able to monitor boom and stick positions using load-sensing hydraulics. Common machine-control functions now are located on the operator’s joystick, simplifying operation when using the 3D grade control. Komatsu America; www.komatsuamerica.com
