The new truck shares major components with a number of Cat machines to help ensure good parts availability and reduce inventory costs. The wide body design makes loading faster and easier. Multiple dump body sizes are available to optimise the truck for all mining applications suited to this size class. The AD22 also takes advantage of Caterpillar ergonomic designs to create controls and instrumentation that help operators perform efficiently.
