KOMATSU WA470-5 WHEEL LOADER

Technical Description

The Komatsu WA470-5 wheel loader is a robust, high-performance machine engineered for heavy-duty construction and quarry applications. It features a powerful Komatsu SAA6D125E-3 six-cylinder, turbocharged diesel engine delivering 271 hp (202 kW) at 2000 rpm with peak torque at 1400 rpm, ensuring efficient power output and low emissions. The loader has an operating weight of approximately 50,221 lbs (22,780 kg) for excellent stability and traction. Equipped with a 5.4 cubic yard (4 m³) heaped capacity bucket measuring 9.9 ft (3 m) in width, the WA470-5 offers a breakout force of 41,365 lbs (18,763 kg), enabling high material penetration and handling capacity. It has a maximum dump clearance of 10.2 ft (3 m) and a hinge pin height of 14.3 ft (4 m), facilitating effective loading and dumping in various work settings. The machine's dimensions include a length of 29.2 ft (9 m) with the bucket on the ground, 9.6 ft (3 m) width over tires, a wheelbase of 11.4 ft (3 m), and a ground clearance of 1.8 ft (0.5 m). The 26.5 R25 tires and a turning radius of 20.4 ft (6 m) enhance maneuverability. The hydraulic system uses a gear pump with a flow capacity of 108.4 gallons per minute (409 L/min), supporting fast cycle times: raise time of 6 seconds, dump time 1.4 seconds, and lower time 3.7 seconds. Transmission is an automatic powershift type with 4 forward and 4 reverse gears, enabling speeds up to 24.7 mph (39 kph) forward and 25.5 mph (40 kph) in reverse. The hydraulic relief valve is set at 3045.8 psi, and the machine operates on a 24V electrical system with a 50A alternator, ensuring reliable operation. Fuel capacity is 103.1 gallons (390 L) for extended work periods. Overall, the Komatsu WA470-5 balances power, efficiency, and durability for demanding applications.
