What a belly dump does best
Most operators call this a belly dump (a matched pair pulled together is a "belly dump train"). Clamshell gates in the bottom open and a belly dump lays a clean windrow of aggregate under the trailer while the truck keeps rolling, so one pass spreads road base without a second machine. That's why paving and grading crews run them. They want clearance under the gates and don't love large chunks or sticky, wet spoil that bridges the opening — for that, look at an end dump.
