Semi-Bottom Dump Units

Transfer Dump Unit

5 axle, 20 yd.

A semi bottom dump (or "belly dump") is a 3-axle tractor pulling a 2-axle trailer with a clam shell type dump gate in the belly of the trailer. The key advantage of a semi bottom dump is its ability to lay material in a wind row. In addition, a semi bottom dump is maneuverable in reverse, unlike double and triple trailer configurations.
