Belly Dump Trailers For Sale

Belly dump trailers for sale

Belly dump trailers (also called belly dump gravel trailers) are a staple for bulk hauling when speed, clean material placement, and stability matter. Instead of tipping like an end dump, a belly dump trailer releases material through bottom gates, letting operators spread aggregate in a controlled windrow while staying level. This makes them a strong fit for road building, paving support, site prep, and long-haul aggregate work where consistent unloading is the priority.

At Ritchie Bros., you’ll find a rotating selection of belly dump trailers for sale across different capacities, axle setups, and manufacturers. Inventory changes frequently through regional auctions and Marketplace listings, so it’s a useful place to compare trailers by size, condition, and configuration, then buy based on what fits your fleet and routes.

What belly dump trailers are best used for

Belly dumps are designed for fast, even unloading on the move. They’re most commonly used for hauling and spreading gravel and crushed rock, sand and base material, asphalt and millings, and dirt and select fill. Because the trailer stays low and stable during unloading, belly dumps are often preferred over end dumps on higher-speed jobs or when rollover risk needs to be minimized.

Single vs. double belly dump trailers

Most buyers will choose between a standard belly dump trailer and a double belly dump trailer (often run as part of a combination/lead-pup setup).

Single belly dump trailers are simpler to operate and maintain, making them a reliable choice for crews running consistent routes or spreading one material type. Double belly dump trailers increase payload and efficiency on big aggregate jobs, especially when you want two controlled drops in one pass or you’re running higher-volume contracts.

Belly dump trailer capacity and sizing

Capacity is one of the main filters buyers use in this category. Belly dump trailer capacity is usually expressed in cubic yards and paired with axle configuration to meet local weight limits and haul needs.

Typical capacity bands you’ll see include smaller units for light aggregate or tighter sites, mid-capacity trailers for general hauling and roadwork, and high-capacity configurations for long-haul and production spreading. If you’re choosing between sizes, the best fit comes down to your material density, legal gross weight limits, and whether your routes favor payload volume or maneuverability.

Popular belly dump trailer manufacturers

This category often includes trailers from major builders and fleet staples, including Armor Lite belly dump trailers, Beall units, CPS belly dump trailers, and other regional manufacturers depending on market and season. You’ll see a mix of standard gravel models, lightweight specs for higher payload efficiency, and heavier-duty builds for tougher sites and longer service cycles.

Belly dump trailer parts and support

If you’re shopping used, parts availability is a practical consideration. Our listings may include trailers with existing gate assemblies, hydraulics, and liner setups, and many common builders have well-supported aftermarket ecosystems. If you’re searching for belly dump trailer parts or specific components tied to manufacturers like CPS or Beall, checking the listing details can help confirm gate style and compatibility before you commit.
