A dump truck is a type of truck that is typically used to transport large loads of materials such as dirt, gravel, sand, and other materials. The truck is designed with a large open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front end, allowing the material in the bed to be deposited onto the ground behind the truck. Dump trucks are commonly used in the construction and mining industries, as well as other industries that require the transport of large amounts of material.
