Off-road dump trucks are used strictly off-road for mining and heavy dirt hauling jobs. There are two primary forms: rigid frame and articulating frame.
The term ‘dump’ truck is not generally used by the mining industry, or by the manufacturers that build these machines. The more appropriate term for this strictly off road vehicle is “haul truck” and the equivalent European term is ‘dumper’. The classification describes how loaded material is discharged from the dump body and in this case, the load is discharged from the rear.
