Komatsu America Corp. introduced its new PC650LC-11 hydraulic excavator with an operating weight between 140,456 lbs. and 145,284 lbs., as well as improved fuel efficiency, upgraded cab design, and enhanced serviceability. It is equipped with the latest KOMTRAX technology that relays fuel levels, Diesel Exhaust Fluid (DEF) levels, operating hours, location, cautions, and maintenance alerts to the web application for analysis. A new Operator Identification System reports key operating information for multiple operators, while a new Auto Idle Shutdown function helps reduce idle time and operating costs.
