New Cat® 794 AC offers proven advantages over the competition

Caterpillar introduced its newest large mining truck, the 291-tonne (320-ton) 794 AC, at MINEpo International in September 2016. But while the truck may be new, the iron and components that go into it are already proven.

The truck uses a combination of proven designs, such as a chassis that has accumulated about 18 million operating hours and an AC powertrain that has racked up 4 million hours.

“The 794 has a fully integrated Caterpillar electric drive system — engine, drive train, software controls, everything,” says Performance Manager John Ingle. “That means we can have better efficiency, and utilize features like Cat® oil-cooled disc brakes on all four corners. All these features come together in one truck that is entirely supported by Cat and Cat dealers.”

Today, after five years of extensive field testing at key mines, 794s are operating in four countries —working in applications ranging from deep pit copper in the western United States to coal and copper in South America.

“Field testing also included comparisons against trucks in this size class that were built by other manufacturers, says Ingle. “These comparisons have helped miners recognize the 794 AC’s advantages over existing trucks in its class — like substantial improvements in their performance and cost per ton.”

Miners who evaluate the trucks are discovering a number of ways the Cat 794 AC outperforms the most popular competitor in the 291-tonne (320-ton) electric drive truck class:

These and other advantages add up to a solid truck that miners can depend on, says Ingle. “Mines running the 794 are confirming the truck is built with proven iron and able to go toe-to-toe with the competition — and win,” he says.

“Now mines using trucks in this size class have a proven Caterpillar option when it’s time to replace their aging 320-ton fleets,” Ingle says. “They don’t have to adjust their operations to a different sized truck or a different drive system.”
