Technical Description

The Komatsu PC800SE-6 is a heavy-duty hydraulic excavator designed for demanding mining and quarry applications. Powered by a Komatsu SAA6D140E turbocharged diesel engine, this machine delivers 443.9 net horsepower at 1800 rpm, providing robust digging and loading capabilities. The excavator features a 930.1 cubic inch displacement engine with a 232.5-gallon fuel capacity, enabling extended operational periods in remote locations. With an operating weight of 165,082 pounds, the PC800SE-6 offers exceptional stability and breakout force. The hydraulic system operates at 4,550 psi relief pressure with a 261.1 gallons-per-minute pump flow capacity, supported by 116.3 gallons of hydraulic fluid. The machine accommodates bucket capacities ranging from 5.3 to 5.9 cubic yards, with a reference capacity of 5.7 cubic yards for standard applications. The excavator's digging dimensions are impressive, achieving a maximum cutting height of 37.8 feet, maximum digging depth of 23.1 feet, and maximum reach along ground of 39 feet. Its ground pressure of 17.5 psi minimizes surface disturbance, making it suitable for environmentally sensitive sites. The track gauge measures 11.5 feet with 24.1-inch shoes, distributing weight effectively across varied terrain. Operationally, the PC800SE-6 maintains a maximum travel speed of 2.7 mph with a swing speed of 5.7 rpm, allowing efficient repositioning on jobsites. The machine's compact shipping dimensions—42.3 feet length and 15.5 feet height—facilitate transportation between locations. The tail swing radius of 14.2 feet and 2.8-foot ground clearance enable operation in confined spaces while maintaining operator safety and visibility from the 12.8-foot cab height.
