Key Specs
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.
Thanks to faster speed on grade in certain applications, for fast cycle times and lower costs
Engine and tire options plus capabilities for specific applications: high ambient, high altitude, extra quiet
Earned 80% of the industry thanks to decades of results and ease of operation and maintenance

Leverage Caterpillar connected data and security principles to improve efficiencies, increase productivity and make your business more profitable.
Cat® MineStar™ Command for hauling takes advantage of the most sophisticated technologies available to deliver a next-generation haulage solution — one that boosts safety, productivity and availability on busy mine sites, especially those in difficult or remote locations. Command provides the fully integrated operation of autonomous mining systems, allowing them to haul more efficiently with near-continuous operation and move more with fewer people on site. Autonomous trucks operate safely around other equipment, light vehicles and personnel. Command trucks respond to calls to the shovel, move into position, haul to dump points and even report for maintenance — all without an operator on board.

Cat® MineStar Fleet is the single best source for fleet management information. An integrated fleet monitoring and management system, it can be used with any machine or system to measure, manage and maximize every facet of an operation, no matter the size or type. Fleet provides real-time visibility to cycle time, payload and other key operational parameters. It monitors machine locations and material movement and provides alerts of misroutes to ensure material is moved to the proper location.

Through regular monitoring of machine conditions, mines can adopt a more proactive approach to maintenance and repair. Equipment health data is a key contributor to that approach. Data helps mines identify equipment problems long before failure.
Accessing the right data at the right time is critical to improving operational intelligence and machine predictive analysis. Cat® MineStar™ Health helps you meet that need by connecting you to your machines and delivering that important information. The MineStar Health portfolio set consists of Connectivity Enablers that collect, convert and transmit equipment data; and Applications that visualize, analyze and report health equipment data.
