Caterpillar is throwing its hat within the electrical mining truck ring. The newly-Texas-based firm gathered suggestions from real-world prospects to develop a battery-powered model of the massive 793, and it demonstrated what the truck is able to at its proving grounds in Arizona.
Electrifying a mining truck makes an amazing quantity of sense: these mammoth automobiles repeatedly haul heavy masses on comparatively quick routes. Caterpillar defined the shoppers who opted to take part within the Early Learner program it launched in 2021 offered the suggestions required to affect the 793, although it stopped in need of revealing exactly what these corporations requested or publishing specs.

Caterpillar factors on the market was sufficient electrical energy left within the truck’s battery to finish extra testing cycles however it hasn’t launched key particulars just like the pack’s measurement, the truck’s vary, or the charging time. Equally, what’s subsequent stays hazy as of writing: The electrical 793 will presumably attain manufacturing in some unspecified time in the future, and it feels like a number of mine operators are ready in line to purchase one.
