Centerline Side Dump Trailer

Centerline Side Dump

A wide stance and low center of gravity provide the perfect platform for this side dump trailer. Hundreds of engineering features combine to give you a tough trailer meant to last the most rigorous of demands. For a fast, reliable dumping process, Centerline utilizes two 6” fast-acting cylinders fed by a rotary valve. This unique valve maintains a consistent, metered hydraulic flow to both cylinders, preventing tub flex and giving you a longer trailer life.
