Technical Description
The Komatsu WA500-3 wheel loader is a robust heavy-duty machine designed for efficient loading operations. It features a turbocharged SAD140E engine delivering 315 hp at 2100 rpm and displacing 927.6 cubic inches, providing reliable power for demanding tasks. The bucket has a heaped capacity of 6.6 cubic yards (5 m³) and a width of 11.4 feet (3 m), with a breakout force of approximately 55,753 lbs (25,289 kg), allowing substantial material handling and excellent penetration power. The loader offers a maximum dump clearance of 10.5 feet (3 m) and a maximum hinge pin height of 14.8 feet (4 m), facilitating efficient dump cycles.
In terms of dimensions, it measures 30.2 feet (9 m) in length with the bucket on the ground, 10.5 feet (3 m) wide over tires, and 12.7 feet (4 m) tall to the cab’s top. The 11.9-foot (3 m) wheelbase and 21.5-foot (6 m) turning radius support good maneuverability. Operating weight is about 64,970 lbs (29,470 kg), with a static tipping load of approximately 51,588 lbs (23,400 kg).
The hydraulic system uses a gear pump with a flow capacity of 92 gallons per minute (348 l/min) and a relief valve setting of 3045.8 psi, supporting efficient boom raising (6.4 sec), bucket dumping (1.7 sec), and lowering (3.5 sec) cycles. Transmission is a planetary powershift type with 4 forward and 4 reverse gears, enabling a max forward speed of 20.6 mph (32 kph) and reverse speed of 22.5 mph (35 kph). The loader runs on a 24-volt electrical system with a 50-amp alternator. Fuel capacity is 121.6 gallons (458 l), promoting extended operational periods between refueling. Tires are sized 26.5-25, suitable for heavy loading conditions. Rear axle oscillation is 30°, enhancing stability on uneven terrain. This combination of power, capacity, and durability makes the WA500-3 versatile for mining, quarry, and heavy construction tasks.
