centerline live bottom trailer

Centerline Live Bottom Trailer

Live bottom trailers provide a safe alternative to dump trailers by utilizing a horizontal rear discharge conveyor system that pushes material out of the back of the trailer at a controlled pace. This means that you can quickly and safely unload materials without raising the bed. Live bottom trailers are ideal for working off road, under high line wires, in tunnels, under bridges, inside buildings, on steep grades, and on high bank returns.
