The Cat 789D Mining Truck has a history of proven performance in a wide variety of applications. It delivers the lowest cost per ton in its size class, for an overall reduction in your operating costs, along with the reliability and reduced costs that come with long life — from the engine and powertrain to the components, brakes and frame. It also delivers fast speed on grade and a high production capability thanks to a payload advantage over competitive machines. The versatile 789D offers engine options to meet regulatory standards or application-specific needs such as extreme temperatures, high altitude or areas that require sound reductions. And it features safety enhancements like diagonal stairways, wide walkways and optional powered access to protect your most important asset: your people.
Three cab options — standard, deluxe and cold weather — allow you to select the best features for your application. All options offer an ergonomic layout, excellent all-around visibility, and controls, levers, switches and gauges that are positioned for ease of use. The cab has numerous features that enhance comfort and reduce fatigue, such as an air suspension seat, reduced vibration, automatic climate control and sound suppression.
Time spent on regular maintenance procedures is reduce with easy access to daily service points and major components; ground-level access to tanks, filters, drains and engine shutdown; a maintenance platform that provides access to the engine engine, steering hydraulic tank and battery compartment; and an optional fast-fill service center, which enables high-speed fuel and oil exchange.
