KOMATSU PC800LC-8 CRAWLER EXCAVATOR

Technical Description

The Komatsu PC800LC-8 is a heavy-duty hydraulic crawler excavator engineered for large-scale quarrying, mining, and material handling operations. Powered by a SAA6D140E-5 turbocharged engine producing 487 net horsepower at 1,800 rpm, this machine delivers 363 kilowatts of net power with exceptional fuel efficiency. The excavator features a sophisticated variable-capacity piston pump hydraulic system with a maximum relief pressure of 4,980 psi and flow capacity of 261 gallons per minute, enabling powerful digging force and precise control. The PC800LC-8 offers multiple boom and arm configurations to suit diverse jobsite requirements. Material handler configurations provide maximum reach heights up to 72.9 feet and ground reach distances of 68 feet, while standard excavator options deliver digging depths exceeding 34 feet with maximum cutting heights of 41.7 feet. The unit produces a maximum swing torque of 209,461 foot-pounds at 6.8 revolutions per minute, facilitating efficient material manipulation. With an operating weight of approximately 179,900 pounds, the machine accommodates a 4.1 cubic-yard bucket capacity and generates a maximum drawbar pull of 125,660 pounds. The hydrostatic transmission provides two forward speeds with a maximum travel velocity of 2.7 miles per hour. The undercarriage features 51 track shoes per side with 9 track rollers and 3 carrier rollers each side, delivering exceptional stability and traction. Advanced cab features including Komatsu's Safe SpaceCab design prioritize operator safety, while low-vibration boom circuits and sound-dampened cabins reduce operator fatigue during extended operations.
