A dump truck is a piece of heavy duty equipment used in many different aspects of the construction industry. The dump truck gets its name from its tippable bed that is lifted on one side to dump out the material it is hauling. While there are few limits to what they can transport, dump trucks most frequently carry sand, rocks, or demolition waste from construction sites. The most common types are standard dump trucks, articulated dump trucks, rigid dump trucks, and tracked dumpers. The most popular dump trucks used in the United States are made by Mercedes-Benz, MAN, Iveco, and Volvo.
