1973-1990 KOMATSU WA600-3 WHEEL LOADER

Technical Description

The Komatsu WA600-3 is a heavy-duty wheel loader designed for high performance in mining and quarry applications. It features a turbocharged 6-cylinder SAA6D170E-3 engine delivering 522 hp gross power and 458 hp net power at 2000 rpm, enabling robust operational capacity. The loader boasts a bucket breakout force of 82,898 lbs (37,602 kg) with a heaped bucket capacity of 8 cu yds (6 m³) and struck capacity of 6.7 cu yds (5 m³), supported by a bucket width of 12.1 ft (4 m). Critical operational dimensions include a wheelbase of 13.5 ft (4 m), total length with bucket on ground of 30.5 ft (9 m), height to cab top of 14 ft (4 m), and a dump clearance at max raise of 11 ft (3 m). It offers a turning radius of 27.9 ft (8 m) and ground clearance of 1.7 ft (0.5 m), facilitating maneuverability on rugged terrain. The hydraulic system supports a pump flow capacity of 130 gal/min (492 l/min) with relief valve settings at 3000 psi. Hydraulic cycle times are optimized with raise time of 8.2 seconds, dump time of 2.4 seconds, and lower time of 4.3 seconds. The machine has an operating weight of approximately 101,777 lbs (46,165 kg), ensuring stability during heavy-load operations. The transmission is an automatic, full powershift planetary gear type with four forward and four reverse gears, achieving maximum speeds of 22.7 mph (35 kph) forward and 24.9 mph (39 kph) in reverse. Fuel capacity stands at 177 gallons (670 liters), with additional fluid capacities supporting cooling, hydraulic, and transmission systems. Tire size is 35/65-33 24PR (L4), suited for robust off-road conditions. Rear axle oscillation is 26°, enhancing traction and versatility on uneven surfaces. Operating voltage is 24 V with a 75 A alternator supplied amperage, indicating modern electrical capacity for auxiliary systems. This combination of power, capacity, and dimension makes the WA600-3 suitable for heavy loading and earthmoving tasks in demanding environments.
