Overview
The 785 Large Mining Truck 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. And now it’s the first to combine a game-changing level of efficiency with industry-leading physical availability to deliver the next generation of productive hauling. It all starts with the operator, who sits in a state-of-the-art environment designed for efficiency and equipped with features that increase comfort, automate functions, provide real-time information and boost confidence. The 785 also delivers significant improvements in serviceability and reliability, enhanced connectivity and easier technology integration. These improvements — and more — take an already proven truck to the next level of productivity.
