History and service record of 793D

Five configurations. Caterpillar builds the 793D in five configurations so customers can match the truck to their application, and positions its empty machine weight as an advantage over competing trucks in the class, since a lighter empty truck can carry more payload for the same gross weight. Caterpillar, 793D Mining Trucks product page.
Built to be rebuilt. Caterpillar markets the 793D's long service life around the option to rebuild it for multiple working lives rather than retiring the truck outright, which is how a mine spreads the truck's high purchase cost over more total operating hours. Caterpillar, 793D Mining Trucks product page.
