The Komatsu PC450LC-6 is a powerful crawler excavator engineered for demanding earthmoving and construction applications. Powered by a turbocharged Komatsu SA6D125E-2 diesel engine, this machine delivers 306 net horsepower at 1,950 rpm, providing exceptional digging force and productivity. The excavator features a 2.7 cubic yard bucket capacity and operates at a maximum travel speed of 3.4 mph with a drawbar pull of 74,957 lbs, making it suitable for heavy-duty operations. Equipped with an advanced Electronic Closed-Centre Load Sensing (E-CLSS) hydraulic system called HydrauMind, the PC450LC-6 optimizes fuel efficiency and precision control. The machine offers five distinct working modes—heavy operations, general operations, finishing, lifting, and breaker operations—each automatically adjusting engine speed, pump speed, and system pressure for optimal performance. With a swing speed of 9.1 rpm and an operating weight of 96,474 lbs, this excavator delivers robust stability and control. The working envelope varies based on boom and stick configuration, with maximum digging depths ranging from 17.7 to 27.1 feet and maximum reach along ground from 35.5 to 42.5 feet, providing versatility for diverse jobsite requirements. Ground pressure of 11.1 psi minimizes ground disturbance, while the 49 shoes per side ensure reliable track performance. The cab height of 10.8 feet and tail swing radius of 12 feet facilitate operational efficiency in confined spaces. With a hydraulic pump flow capacity of 172.3 gallons per minute and comprehensive diagnostic capabilities monitoring 119 potential problems, the PC450LC-6 represents a reliable, fuel-efficient solution for professional excavation work.
