Komatsu's PC800LC-8 excavator has an improved Tier 3 diesel engine that produces 487 horsepower. Operating weight is between 179,400 and 192,240 pounds with bucket capacities ranging from 2.23 to 5.93 cubic yards. Two working modes match engine speed, pump flow and system pressure to specific tasks. New arm quick-return circuit returns a portion of oil flow directly to the hydraulic tank for arm dumping, which reduces pressure loss and increases loading speed. Komtrax wireless technology and EMMS provide monitoring and maintenance information. Estimated list price: $960,000.
