KOMATSU PC650LC-8 CRAWLER EXCAVATOR

The Komatsu PC650LC-8 is a heavy-duty hydraulic excavator engineered for high performance in demanding environments. It is powered by a Komatsu SAA6D140E-5 engine delivering 429 hp (320 kW) at 1800 rpm, combining robust power output with advanced fuel efficiency and compliance with Stage 3A/EPA Tier 3 emissions standards. The machine’s operating weight ranges up to 146,390 lbs, enabling exceptional stability and strength for large-scale excavation and material handling tasks. Its maximum digging depth is 27.8 feet, with a maximum reach along the ground of 42 feet, facilitating extensive operational flexibility. The excavator features a ground clearance of 2.6 feet, has an overall height of 10.8 feet to the top of the cab, and measures 11.5 feet in width across the tracks, offering balance between reach and transportability. The undercarriage includes 52 track shoes per side, 3 carrier rollers, and 9 track rollers, supporting a maximum travel speed of 3 mph and a drawbar pull of 93,250 lbs for reliable mobility on rough terrain. Hydraulics are managed through an open-center load-sensing variable displacement piston pump system with a hydraulic fluid capacity of 95 gallons, supporting precise control over boom, arm, bucket, swing, and travel circuits. The swing system achieves speeds of 8.3 rpm with a fluid capacity of 6.8 gallons. The machine is equipped with features such as lift mode to increase lifting capacity by 17%, economy mode levels for fuel savings, and electronically controlled variable-speed fans for optimal cooling with a coolant capacity of 15.3 gallons. Fuel capacity is 232.5 gallons, maximizing operation time between refueling. Designed with operator comfort and serviceability in mind, the PC650LC-8 offers easy engine access, low operational noise meeting EU Tier 2 standards, and robust structural components built from high-tensile steel for durability and long life in heavy construction and mining applications.
