Boise, Idaho 83716 Our unique frame-less design provides superior strength with light weight.

In 1975, we developed and built our first self-unloading feed, seed and fertilizer belt trailer. The revolutionary “Eagle Bridge” design concept, introduced in 1977, established Trinity Trailer’s national reputation for excellence and innovation. It’s a brilliant combination that has stood the test of time. Trinity Trailer’s “Bridge” design and construction provide a number of benefits unavailable

in conventional self unloading belt trailers. Flexibility means our trailers can withstand rough, demanding conditions without structural damage. Strength without mass means our trailers are durable while maintaining an overall lighter weight. Versatility means an “Eagle Bridge” Trailer can haul a variety of payloads. Whether your application calls for a carbon steel, a stainless steel or our rugged Agri-Flex trailer, all Trinity Trailers can be configured to meet the needs of virtually every bulk hauler.
