During long pushes, the automatic gearshift mode allows the system to automatically engage the torque converter lockup clutch. Komatsu’s lockup torque converter produces a more efficient transfer of power to the driveline, designed to help decrease cycle times and increase production. Increased production less fuel consumptionĮngineered for exceptional production, the D475A-8 mining dozer is designed for power, stability and solid performance. The D475A-8’s high horsepower in reverse means the lock-up converter stays engaged more frequently, allowing significantly higher levels of production, especially when pushing down slopes. Blade capacity: 27.2-45.0 m 3 (35.6-58.9 yd 3)Īdditional horsepower can provide for faster ground speeds, shorter cycle times and more production tons per hour, when appropriate.Net horsepower: Reverse – 722 kW at 2,000 rpm (968 hp at 2,000 rpm).Net horsepower: Forward – 664 kW at 2,000 rpm (890 hp at 2,000 rpm).Track shoe slip control automatically controls engine speed and minimizes slip during ripping. Its low center of gravity provides machine stability and long and consistent track on ground length offers more traction, pushing power, ripping efficiency and less shoe slippage. Using extensive customer feedback, Komatsu re-engineered the D475A-8 mainframe to target twice the life of previous models and withstand multiple rebuild/overhaul cycles. If your operation needs a versatile mining dozer that can go from ripping solid rock to cleaning up around the dragline, take a look at the new Komatsu D475A-8. On mining sites, support machines, like dozers, can directly impact productivity by keeping blasting, loading and dump areas clean, enabling loading and hauling equipment to work more efficiently.
