Biosolids Hauling Made Easy | Efficient Unloading Solutions | Trinity

Trinity EAGLE BRIDGE self-unloading trailers streamline biosolids hauling—no tipping required, remote operation keeps drivers out of the trailer, and optional moisture and flap containment systems help keep liquid and debris off the road.

For municipalities that have invested heavily in wastewater solids processing—whether advanced dewatering is in place or not—dump trailers remain common, but inefficient. Plus, there’s a high risk when the product sticks. There’s a better way to haul and unload. It’s with the EAGLE BRIDGE.

Higher Payloads

Engineered for the demanding characteristics of biosolids, Trinity belt trailers hold the highest long-term reliability. Our self-unloading belt system improves safety at treatment plants and land application sites. With efficient clean-out, you can move more biosolids in fewer trips, reduce cycle times, and keep operations compliant and productive.

Cleaner Unloads

Our trailers feature welded HMW or UHMW plastic liners that prevent sticky biosolids from building up behind the liner, making unloads faster, smoother, and more efficient. Cleanup is quick and easy — just a simple power wash gets you back on the road.

Safety First

Biosolids don’t wait—and neither should your customer. The EAGLE BRIDGE is proven to handle changing moisture levels and year-round demand, delivering reliable performance from field to freeway when it matters most.

From kingpin to tail lights, every EAGLE BRIDGE is designed and built to meet our customer’s unique needs, and the products being hauled.

Stainless steel is superior when it comes to preventing corrosion, which is critical when hauling poultry litter, fertilizer and other corrosive products.

The frameless, steel trailer design allows the trailer to flex and twist as the ground demands, helping prevent the trailer from cracking.

Our trailers unload quicker and cleaner so your drivers can spend their time behind the wheel instead of cleaning out the trailer bed.

Accessible components and the frameless design make Trinity trailers the most reliable, easiest to maintain trailers available.

Trinity belt trailers resale values are higher than any other self-unloading belt trailer on the market, giving owners the best possible long-term ROI.
