These D-series ADTs handle heaped payloads with faster cycle times and best-in-class fuel efficiency - so you'll move more material at lower cost. They're highly reliable too, with high-strength, welded-alloy steel chassis and components that are durable and optimized to reduce unnecessary weight. And with their oscillating frame joint, articulated steering and high-floatation tires, these hard working haulers won't let wet weather or steep grades dampen your plans.
