Key Specs
The Cat® 785 model was Caterpillar’s first entry into the mining industry more than three decades ago and has been a proven performer on sites around the world ever since. The 785D carries on that tradition.
It’s engineered for performance, designed for comfort and built to last. Developed specifically for high production mining applications, the 785D keeps material moving at high volume to lower your cost-per-ton. Rugged construction creates a durable machine, while easy maintenance procedures ensure high reliability and long life with low operating costs.
Ensures high reliability and long life with low operating costs.
Rugged construction creates a durable machine with demonstrated reliability and proven performance.
Thanks to health technologies, features that increase component life and settings to optimize performance.

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.

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.
