![]() ![]() ![]() “It also has fewer maintenance points and enhances operator visibility to the blade.” “The all-new blade support structure is designed to significantly reduce blade side sway,” the OEM explained. The machine additionally has high horsepower in reverse, allowing the lock-up converter to remain engaged more frequently, allowing significantly higher levels of production, especially when pushing down slopes.īy the numbers, the OEM said the D475A-8 offers an increase of up to 10% in productivity 11.5% more engine power in reverse compared to forward direction and a 10% reduction in fuel consumption with automatic transmission with lockup torque converter (compared to manual gearshift operation).įinally, operators can boost efficiency by working in blade auto-pitch mode, designed to increase dozing efficiency while reducing the amount of operator input required. “Additional horsepower can provide for faster ground speeds, shorter cycle times and more production tons per hour when appropriate.” “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,” Komatsu said, noting that its track shoe slip control automatically controls engine speed and minimizes slip during ripping. It can go from ripping solid rock to cleaning up around the dragline with a net forward horsepower of 722 kW (890 hp) at 2,000 rpm. With an operating weight of 115,300 kilograms (254,193 pounds), the new D475A-8 features a blade capacity of 27.2-45 cubic meters (35.6-58.9 cubic yards). ![]() The OEM said the new machine was designed using extensive customer feedback and is a re-engineering of past D475 models, this time with the capacity to handle twice the life span of previous models and withstand multiple rebuilds and overhauls. Versatility and reliability are the focus of Komatsu’s newest equipment release, the D475A-8 dozer. ![]()
