Mining Giant Meets Yard Ghost: Why the Cat 777-07 and Kalmar AutoTT Will Never Share a Jobsite
The Caterpillar 777-07 is a 1,025 hp, 363,000 lb off-highway haul truck built to move 100+ tons of blasted rock across mine pits at 40 mph. The Kalmar AutoTT is a cab-less, electric terminal tractor designed to shuffle semi-trailers around paved distribution yards at 15–25 mph. One lives in dust, grade, and cycle-time obsession; the other lives in concrete, dock doors, and 24/7 autonomous shuffle loops. Their operational envelopes do not touch—no shared payload interface, no compatible infrastructure, no common telematics ecosystem. The 777 dumps into a primary crusher; the AutoTT backs under a 53-foot van trailer. Putting them in the same 'fleet' is a category error, not a strategy. This is a Missed Connection of industrial proportions.
