EAGLE BRIDGE

The Original Self-Unloading Belt Trailer—
Delivering on Today’s Demanding Hauls

A Reputation of Excellence—A Legacy of Innovation

Since inventing and patenting the original self-unloading EAGLE BRIDGE® trailer in 1975, Trinity trailers have excelled at hauling feed, seed, fertilizer and other bulk commodities. We understand delivering bulk materials requires hauling the heaviest loads on the roughest roads, while absorbing the punishment year after year.

With over 50 years of proven success, Trinity is recognized as the leader in the belt trailer market — and we continue to push the boundaries of innovation and design. Our trailers have a well-earned reputation of longevity and durability. Our commitment to quality and reliability is unsurpassed.

What Can You Haul with an EAGLE BRIDGE?

Our Belt Trailer, Built to Meet Your Specific Needs

The Design That Does It All

Ultimate Versatility

EAGLE BRIDGE is one of the most versatile trailers available, engineered to handle a wide variety of commodities. Need a flexible trailer for seasonal operations? Our trailers can be designed for multi-purpose use, making it ideal for both farming and contract hauling, keeping your trailers working year round.

Flexible Design

The EAGLE BRIDGE features a frameless design that allows it to flex up to 36 degrees, enabling smooth navigation over uneven terrain and preventing cracking. It’s perfect for in-field loading or tight spaces like sheds and barns. This results in far fewer repairs, replacement parts and less downtime.

Lightweight + Corrosion Resistant

Our trailers are lightweight without sacrificing strength, allowing higher payloads with every trip. This means more throughput, fewer trips, and increased revenue for farmers and haulers. The stainless steel body not only makes the trailer lightweight, it also stands up to corrosion better than aluminum.
