1993-1996 KOMATSU WA900-3 TIER 2 WHEEL LOADER

Technical Description

The Komatsu WA900-3 Tier 2 is a heavy-duty wheel loader engineered for demanding material handling and earthmoving applications. Powered by a SAA12V140E-3 turbocharged and aftercooled 12-cylinder engine, it delivers 856 net horsepower at 2,050 rpm with a gross output of 900 hp, providing the power necessary for demanding operational environments. The machine features a heaped bucket capacity of 17.1 cubic yards (13 m³) with a breakout force of 149,690 lbs, enabling efficient loading and material transport. Dimensionally, the WA900-3 spans 47.6 feet in overall length with a 15.1-foot width over tires and 17.4-foot cab height, providing excellent visibility and maneuverability on jobsites. The 17.9-foot wheelbase and 1.9-foot ground clearance ensure stability across varied terrain. Operating weight reaches 236,340 lbs (107,203 kg), delivering substantial traction and load-bearing capability. The hydraulic system incorporates a variable capacity piston pump with 83.3 gallons per minute flow capacity and 4,977 psi relief valve setting, enabling rapid cycle times including 2-second dump, 11.2-second raise, and 4.8-second lower operations. The powershift transmission offers three forward and three reverse gears with maximum speeds of 10.9 mph forward and 11 mph reverse. The machine carries 191.6 gallons of hydraulic fluid and 410.8 gallons of fuel capacity, supporting extended operational periods. Static tipping capacity of 144,780 lbs demonstrates its load-handling capability, making it suitable for high-production loading and material movement applications.
