HAULING AGGREGATE & MINING PRODUCTS

Rugged Dependability Meets Performance

A good aggregate trailer has to be tough for the rugged roads they drive and the products they haul. To get the job done right, you need durability, dependability (little down time), and tough (but lightweight) trailers that can safely handle rough terrain. The Trinity EAGLE BRIDGE® is a large capacity, self-unloading belt trailer designed to help you make the most every trip to the mine. Whether backhauling sand or crushed gravel, delivering copper concentrate, or chunks of coal, Trinity trailers are ready to handle the job. Some of the most common mining products our customers haul include:

Hauling fly ash from paper mills or coal burning operations presents numerous challenges to drivers and truck/trailer operators. Fly ash packs in tight while going over the road and in a dump trailer, and that can be quite hazardous when it comes time to unload.

A Trinity EAGLE BRIDGE trailer or EAGLEBED truck bed delivers a fast, yet safe unload without tipping. Since fly ash is so powdery, we also offer a tarp system equipped with ports in the top for top loading with the tarp closed.

Hauling gypsum from a mining operation or to a farm field? You will appreciate the steep slope of the 48” or 61” belt EAGLE BRIDGE belt trailer for a clean unload in or out of the field. Our trailers are known for their versatility, making it easy to haul, and backhaul, a variety of commodities and products easier than any other trailer on the market. 

In some mining operations, having a wired or wireless remote-controlled door and conveyor system may be required. We offer multiple remote options that can be installed at the factory.

Transporting coal from a mine facility to a dump site presents challenges that an EAGLE BRIDGE can help overcome.

Without the risk of tipping, like there is with a dump trailer, and the lightweight and rugged design, you can rely on your Trinity belt trailer to get the job done safely and efficiently. Trinity trailers excel at hauling crushed coal due to their robust construction and customizable features.

Tough as Nails

The harsh demands of mining pit roads, fields, and loading operations are no match for our stainless steel trailers. Day after day, year after year, Trinity trailers are designed to take the punishment. With the optional thicker gauge stainless steel floor and sides, it’s guaranteed to hold up.

Efficient Unloading

Unload in minutes—safe from overhead obstructions, high winds, or product sticking. With high-torque motors and rugged, high-tensile components, the EAGLE BRIDGE matches dump trailers for unload speed while ensuring easy, safe operation.

Versatility

Easily haul multiple products with a Trinity belt trailer. Switching from copper concentrate or crushed coal to gravel or sand requires no additional setup or preparation. You can focus on hooking your EAGLE BRIDGE to your truck, and never having to unhook.

Why Choose an EAGLE BRIDGE® Trailer?

CUSTOM BUILT

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

FLEXIBILITY

The frameless design allows the trailer to flex and twist — up to 36 degrees —under the heaviest loads as the ground demands to help prevent cracking.

CORROSION RESISTANT

Stainless steel is superior when it comes to preventing corrosion, and Trinity provides the industry’s ONLY stainless steel belt trailer.

LESS MAINTENANCE

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

Choose the Options That Meet Your Needs

There are Endless Ways to Customize Your New Trinity Trailer

LINER OPTIONS

Adding a 1/4” UHMW (Ultra High Molecular Weight) plastic side liner all the way up to the top rail will be your best bet to handle abrasive loads. If you haul a high temperature product, you may also consider our “Red Hot” UHMW liner.

HEAVY GAUGE STEEL AND SUSPENSION

While dirt and sand is a piece of cake, if you’re dropping huge chunks of coal during the loading process, you’ll want to consider a heavy duty stainless ⅛” floor and slope. That kind of haul may also require our rugged 30,000 lb axle and suspension configuration.

RADIAL PISTON MOTOR

When ordering your trailer, a radial piston Hydraulic Motor is a popular upgrade that can be selected to ensure a successful — and quick — unload.

REMOTE OPTIONS

Your driver in many operations will probably be required to stay in the cab — the wired or wireless Remote Control unloading system will be a terrific option for you.

SCALE OPTIONS

We also offer various scale systems to weigh your load to avoid tickets and assure maximum payload. Select a bluetooth digital scale for added convenience.
