Overview

At 22 tonnes (24 tons), the Cat AD22 represents a new size class for Caterpillar with industry leading capacity for its size. This truck is powerful, quick and nimble. It is extremely productive in compact mining conditions on less than ideal haul roads. It can also be uniquely configured for your mine with different cab and body options (including an ejector body). The AD22 uses the C11 ACERT diesel engine and other Cat power train components to produce excellent low-end torque, speed on grade and top speeds of 25.3 km/h or 15.7 mph in 4th gear.
