745 articulated dump truck

Articulated dump trucks (CAT)

The 745 Cat, with a capacity of 25 m³ (32.7 yd³) and a weight of 41 tons (45.2 US tons), brings a new level of comfort and functionality to the operator, in addition to the long service life, high productivity, and low operating costs that Cat articulated haulers are known for. The all-new operator cab is a major step forward for articulated haulers, providing our operators with the best possible environment to help build the future.
