A dump truck is a large vehicle designed to transport loose materials such as sand, gravel, or dirt. It features a bed that can be raised at the back, allowing the contents to be dumped out easily at a construction site or other locations. This design makes it efficient for moving heavy loads quickly. Dump trucks come in various sizes and configurations, including standard dump trucks, articulated dump trucks, and transfer dump trucks. They are commonly used in construction, mining, and landscaping industries, playing a crucial role in transporting materials and facilitating various projects.
