Komatsu America has launched the new PC390LCi-11 hydraulic excavator, which according to the company, is a 3D semi-automatic model that features the nimbleness and speed of the popular 36-ton weight class machines and stability of much larger machines.
The intelligent machine control feature comes with a sensor package that includes stroke sensing hydraulic cylinders, an IMU sensor, and GNSS antennas It uses 3D design data loaded into the machine’s monitor to display machine position relative to target grade. Automation is activated when the bucket reaches the target surface to limit over excavation.
Other key features include Intelligent Machine Control Joysticks that feature a semi-auto/manual switching and design surface offset function that can be operated with switches on the control levers. The product also has an Auto Grace Assist that adjusts the bucket height automatically and an Auto Stop Control that automatically stops when the bucket edge reaches the design surface.
Renee Kafka, product specialist, Komatsu America, said: “Whether it’s production excavating, utility trenching, site prep or any application where greater over-the-side lift capacity is required, this could be the machine operators fight over on the jobsite. Also, to increase operator comfort and convenience, all PC390LCi-11 machines come standard with the machine-control-enhanced joysticks first introduced on the PC210LCi-11.”
