Centerline Tridem 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.
Trailer Features
Frame
We use a 110,000 PSI tensile frame flange and webb, while the majority of other trailers only use high tensile flanges.
Crossmembers
Engineered laser cut flared end crossmembers increase torsional twist strength making the trailer much more stable.
Box Strength
The Centerline side dump box is constructed from 400 – 500 brinell strength steel which is extremely wear & crack resistant, giving you a long life cycle.
Dump Angle
The rolled box combined with a steep side dump angle ensures optimum clean out.
Latch
Comes equipped with a quick change manual latch system for dumping curb or street side.
Side Controls
Allows ground crew to manually dump the box when needed.
