Patriot Self Unloading Belt Trailer

The year around versatility of the self-unloading Patriot belt trailer coupled with the practicality of its long-lasting and lightweight aluminum construction lends itself to years of service and greater payloads. Wilson's smooth aerodynamic sidewall design reduces wind drag, increases fuel economy, and makes the live bottom belt trailer easier to pull. The trailer stays clean longer, reducing maintenance and the associated costs.

Realize the Patriot's full hauling potential from season to season with such products as corn, potatoes, gluten, hay cubes, gravel and limestone – All unloaded in just a few minutes. The Patriot belt trailer is standard with the best features and it has all the available options necessary to make this trailer meet your hauling requirements.

Side Walls

The Patriot's smooth sidewall offers superior aerodynamics with increased fuel economy and a cleaner, better appearance. Promoting insulating properties not available on single wall trailers, products like corn gluten can be hauled in colder climates and less likely to freeze.

  • Riveted construction allows the Patriot to flex to varying surfaces. The Patriot is made tough for hauling in or out of the field or the feedlot.
  • The Patriot's smooth side allows graphics or decals to be easily applied to promote your business.

Front End

  • The accessible adjuster located on the front rail so chain tension adjustments can be made easily.
  • A stainless steel hinged door is provided for access to the front area of the trailer.
  • The Patriot features the trademark polished stainless steel radius corner panels.
  • Ladders and walkways feature non-slip surfaces for better operator safety.

Conveyor Chain/Flaps

Multi-ply rubber flaps are attached to extruded and enclosed aluminum cross bar tubes and two lengths of chain. Flaps hang under the trailer to help them self-clean before completing the revolution back into the trailer.

On the inside of the trailer, the flaps lie flat under the load but develop large pockets to positively grip product. This helps to eliminate bridging the product as it moves out of the rear of the trailer.

Floor Pan

The completely enclosed flat floor pan under the chain conveyor retains high moisture product and extends floor liner life.

Side Liner

The HMW liners of the Patriot used on the diagonal slopes sheets provide quick and smooth unloading of even the stickiest of products. An optional UHMW liner is available for abrasive products like gravel.

The standard UHMW free-floating floor liner under the chain is designed to expand and contract freely with ambient temperatures and extend the floor life.

Side Slope

The Patriot's 45-degree slopes allow a majority of products to be hauled and unloaded fast and clean.

Side Vents

Side vent ports, positioned between each set of side posts, extend the life of the sidewall by allowing the sides to breathe. The vent ports also serve as an inspection source.

Door Latches

Premium stainless De-Sta-Co latches help the door to maintain a tight seal plus support the lower corners of the rear door.

Door Hinges

Adjustable Door Hinges

Adjustable door hinges help to align the rear door and maintain a good fit.


The Roller/Receiver allows the door to align with the latches when the trailer is on uneven surfaces.Rear door steel components like hinges and latches are galvanized to resist corrosion.

Conveyor Drive Motor

A 23:1 planetary drive, driven by a hydraulic motor, powers the conveyor belt. Larger diameter drive sprockets with additional teeth engage the chain better and promote longer service of conveyor chain and drive components.

Rear Dust Shield

The full width aluminum dust shield protects brakes, wheels and suspension area from product and debris buildup.

Ladder and Grab Handles

The Patriot features an easy-enter ladder and grab handles both inside and outside of the trailer.

Conveyor Controls

A hinged stainless door protects hydraulic conveyor controls and components from the elements.


The Patriot's tarp features a beneficial moisture barrier flap to help keep product dry.

Door Options - Side Swing Door
with Hydraulic Slide Gate

This door works best for grains and like products. The rear door will swing to the side and allow bulky commodities to be unloaded and the slide up gate allows for product metering. This is the Patriot's standard door.

Door Options - Hydraulic Top Hinge Door

The hydraulic top hinge door is most useful for hauling dense commodities that do not require any metering or slowing by the door. This door will open up hydraulically to a horizontal position or as far as 90 degrees. This door is popular in sugar beet and gravel operations.

This door works best for sand and gravel, feedlot stuff, sugar beets, coal, manure, and topsoil.

Door Options - Spud Door

The Spud Door features a flip up lower portion for unloading. The fold down upper piler door allows a piler to load into the trailer through the rear.

Conveniences include spring loaded slam latches, easy access ladders, and electric controls within the operator's easy reach.

Aluminum Extensions

Aluminum side extensions provide temporary additional capacity for seasonal commodity demands.


Sideliner options include full height liners, 57-degree slopes, over-lapping sideliners, and for abrasive products like gravel, UHMW liners are available.


Weight restrictions and allowances vary greatly from state to state and from country to country; therefore making the selection of the correct suspension matched to the type of load all the more important. Wilson provides a variety of optional suspensions to make the most of gross weight limitations.
