Belly dump trailers have raised sides, open tops for loading and gates at the bottom of the trailer belly for unloading. They are designed to minimize weight and maximize payload.
Belly dumps are commonly used for hauling rock, sand and other aggregate product. They are often used in large construction and paving projects.
Air cylinders control the opening and closing of the belly dump gates. This can be operated from the trailer or wired into the truck cab.
