Technical Description
The Komatsu WA480-6 is a large wheel loader engineered for high productivity and reliability in demanding applications. It features a robust SAA6D125E-5, 12-cylinder, turbocharged engine delivering 300 hp (224 kW) at 2,000 rpm, ensuring strong performance and fuel efficiency. The loader is equipped with a large-capacity torque converter and a full-powershift, countershaft transmission, providing smooth gear changes and four forward and reverse speeds, with a maximum forward speed of 21.4 mph (34 kph). The articulated, full-hydraulic power steering system allows for a 35-degree articulation angle, enhancing maneuverability in tight spaces. The WA480-6 has a rated bucket capacity of 5.4 to 8 cu yds (4 to 6 m³), with a bucket width of 10.5 ft (3 m), and a breakout force of 47,660 lbs (21,618 kg), making it suitable for heavy-duty loading and carrying tasks. The hydraulic system utilizes a double-acting piston pump, offering a flow capacity of 63.9 gal/min (238 l/min) and a relief valve setting of 3,555 psi, with fast cycle times: 7 seconds to raise, 3.8 seconds to lower, and 1.9 seconds to dump. The loader’s dimensions include a length with bucket on ground of 30.7 ft (9 m), a wheelbase of 11.4 ft (3 m), a width over tires of 10 ft (3 m), and a height to the top of the cab of 11.5 ft (3 m). The operating weight ranges from 54,420 to 54,840 lbs (24,685 to 24,875 kg), with a static tipping weight of 45,020 lbs (20,421 kg). The machine also features a large fuel capacity of 109.1 gal (413 l) and generous fluid capacities for cooling, engine oil, hydraulic, and transmission systems, supporting extended operation with minimal downtime.
