Dump trucks, also known as tipper trucks or damper trucks are heavy duty vehicles used for moving dumps (landfills such as sand, gravel, or debris) from one point to another.

These trucks have an open-box bed that is fixed at the rear and fitted with hydraulic rams to lift the front to allow the dump to be discarded behind the vehicle at the site of delivery.

Dump trucks come in various configurations and sizes each designed to undertake a specific task in the mining and construction materials supply chains.

From the D8-774 Mining Truck to Belaz 75710, here are the world’s biggest trucks:
