What do you haul?

“The guys find them easy to operate and now that we’ve been established for ten years, having the same trailers makes it a lot easier to manage maintenance. We haven’t had any issues.”

– Jeff Jeanson, Burbank Express General Manager Read more about their experience with Trinity trailers.

Trusted. Proven. Hardworking.

Since inventing and patenting the EagleBridge trailer in 1975, Trinity trailers have excelled at hauling bulk commodities longer than any other self-unloading trailer. We get that delivering commodities requires hauling the heaviest loads on the roughest county roads, while absorbing the punishment year after year. With over 40 years of proven success, Trinity trailers have gained a reputation of longevity and reliability in the industry of conveyor belt trailers.

Trinity trailers are engineered to contribute to your bottom line.


Anyone who’s run a conventional trailer off-road, in-field or over uneven terrain knows exactly how hard it is on a live bottom trailer. An entire supply chain can be effected by a broken trailer this means lost income. Our unique belt trailers with their amazingly flexible design means more time on the job and far fewer repairs and fewer replacement trailer parts. Buyers who are serious about performance choose the EagleBridge live bottom trailers.


Trinity trailers are engineered to be the lightest weight and most durable live bottom trailers available. We have always had belt trailers for sale that are lighter than the competition, sometimes as much as a ton lighter, which allows for higher payloads and greater throughput. Our semi trailer builders take pride in their craftsmanship and we stand behind the conveyor trailers we have for sale. We have combined our extensive structural analysis, fatigue analysis and the knowledge of our 40+ years of field experience to offer the best belt trailers for sale. Trinity trailer takes being one of the premier semi trailer manufacturers in the USA seriously and this also can be seen in all our agricultural trailer parts we produce.
