Komatsu PC800LC-8 crawler excavatorThe PC800LC-8 hydraulic excavator has an improved Tier 3 SAA6D140E-5 diesel 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. High-production applications include quarry work and large-scale utility work. 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 increasing loading speed. All major components are designed and produced by Komatsu. Komtrax wireless technology and EMMS provide monitoring and maintenance information.
