2004-2008 KOMATSU WA50-3 WHEEL LOADERS

Technical Description

The Komatsu WA50-3 is a compact wheel loader designed for versatile loading, digging, leveling, and pushing operations, with an operating weight of approximately 8,200 lbs (3,720 kg). It features a turbocharged three-cylinder S3D84E-3B engine delivering 37 hp at 2,500 rpm, providing reliable power within a hydrostatic transmission allowing forward and reverse speeds up to 9.3 mph (14 kph). The loader is equipped with a 0.75 cubic yard heaped bucket of 5.6 ft (1.7 m) width and a breakout force of 6,720 lbs (3,048 kg), offering strong digging and loading capacity. The Z-bar linkage design ensures maximum rigidity and powerful breakout, with a dump clearance of 7 ft (2.1 m) at maximum raise and a hinge pin height of 10.3 ft (3 m). Key dimensions include a length of approximately 15 ft (4.55 m) with bucket on ground, a wheelbase of 6.1 ft (1.85 m), width over tires of 5.5 ft (1.65 m), and ground clearance near 1 ft (0.31 m). The hydraulic system features an 11.4 gal/min (42 l/min) pump flow, operating at a relief valve setting of 2,990 psi, and efficient cycle times with dump time of 1 second, lowering time of 2.8 seconds, and raise time of 4.6 seconds. Fuel capacity is 11.9 gallons (45 l), with hydraulic fluid at 7.4 gallons (27 l). Compact and maneuverable, it offers a turning radius of 10.5 ft (3.2 m), ideal for confined work sites requiring robust performance within a small footprint.
