Large piles of sand, gravel, rock, asphalt, ore and countless other types of bulk materials often have to be transported, and in such situations a tipper is often used to do the work. A dumper is also known as a tipper, WAS means the front of the trough can be raised to tilt or drain the load through the tailgate to be opened. Various special companies offer tilt trays for multi-axle heavy-duty chassis from truck manufacturers such as Kenworth®.
