1998-2005 KOMATSU WA470-5H WHEEL LOADER

Technical Description

The Komatsu WA470-5H is a heavy-duty wheel loader engineered for productivity and reliability in demanding applications. It features a powerful SAA6 D125E-3 six-cylinder turbocharged diesel engine delivering 270.9 hp at 1700 rpm and a maximum torque of 1245 lb-ft at 1400 rpm. The machine’s operating weight is approximately 52,514 lbs (23,820 kg), with a static tipping load of about 45,514 lbs (20,645 kg), lending it significant stability and lifting power. The WA470-5H uses a speed powershift transmission with four forward and four reverse gears, enhancing operational control and efficiency. Its hydraulic system incorporates a gear pump with a flow capacity of 108.4 gallons per minute and a relief valve pressure of 3045 psi, ensuring responsive hydraulic performance. The loader accommodates a heaped bucket capacity of 5.4 cubic yards (4 cubic meters), suitable for large material handling tasks. Dimensional specifications include a length of 78.2 feet (24 meters) with the bucket on the ground, a wheelbase of 11.4 feet (3.5 meters), a width over tires of 9.6 feet (3 meters), and a cab height of 11.4 feet (3 meters). It rides on 26.5 R25 tires, providing durability and traction across rough terrain. Fuel capacity is 103.1 gallons (390 liters), supporting extended working hours, and its hydraulic fluid capacity is 49.2 gallons (185 liters). This combination of robust engine power, hydraulic efficiency, and structural design makes the Komatsu WA470-5H well-suited for high-load, high-productivity construction and mining tasks.
