1975-1987 KOMATSU WA800-3 WHEEL LOADERS

Technical Description

The Komatsu WA800-3 is a heavy-duty wheel loader engineered for demanding material handling and loading applications. Powered by a turbocharged and aftercooled 12-cylinder SAA12V140E-3 engine, it delivers 808 net horsepower at 2,000 rpm with a displacement of 1,861 cubic inches, providing robust performance across various jobsites. The loader features a substantial bucket capacity ranging from 10 to 14 cubic meters with a breakout force of 152,120 pounds, enabling efficient material loading and excavation. Built for stability and maneuverability, the WA800-3 measures 47 feet in overall length with bucket on ground and boasts an 18-foot wheelbase. It achieves a maximum dump clearance of 15.5 feet and reaches a hinge pin height of 22.3 feet, facilitating superior dumping capabilities. The machine operates at a maximum forward speed of 17.4 mph with a full-powershift transmission featuring three forward and reverse gears. The hydraulic system incorporates a double-acting piston pump delivering 107 gallons per minute at 4,550 psi relief pressure, with impressive cycle times: 11.2 seconds raise, 2 seconds dump, and 4.8 seconds lower. The operating weight reaches approximately 224,650 pounds, while the static tipping load is 135,033 pounds. Large fluid capacities—including a 376.5-gallon fuel tank and 191.5-gallon hydraulic system reservoir—support extended operational periods. Equipped with 45/65-45-46 tires and a turning radius of 35.9 feet, the WA800-3 combines productivity with maneuverability for demanding loading and material handling operations.
