About Belt Semitrailers
New and used belt trailers, sometimes called “self-unloading trailers,” for sale on TruckPaper.com are a specialized type of semitrailer that features a conveyor belt or chain-and-flap assembly built into the trailer’s floor. When the trailer is parked, the operator can engage an electric or gas-powered motor that drives the belt system to quickly—often in five minutes or less—unload the trailer’s contents through a typically rearward chute or gate. The sloped sides of these trailers are designed to help funnel the trailer’s contents toward the belt as it empties. The belt can range in width from 25 inches to up to 60-inches or more, depending on the model.

Practical Uses For Belt Trailers
Common belt trailer payloads include agricultural commodities such as fertilizers, waste, or feed. They are also used to haul bulk materials, debris, and construction aggregates, among other applications. Belt trailers can be manufactured from steel or aluminum, but the payload capabilities will vary between the two types, with the former being better-suited to the hauling of heavier, more abrasive materials.
