HAULING SEED
Contaminant-Free Hauling
One of the top concerns when hauling seed is the possibility of contamination. Trinity’s stainless steel belt trailers and truck beds are designed to be easily washed before switching loads or when hauling disease-sensitive applications for contaminant-free hauling. Easily power wash the trailer for your next haul, even if your previous load was a dirty one.
Losing a load of seed potatoes can affect the entire food supply chain, so relying on your equipment is key. The Trinity EAGLE BRIDGE® trailer, invented specifically for hauling potatoes, is simply the best choice for keeping your fragile products safe. It provides controlled, efficient unloading, while being durable, and easy to clean and maintain.
Very fine products, such as grass seed or flax seed, have a tendency to leak during transport. Building the perfect trailer to haul smaller seed products is what Trinity does best, since every trailer is customized to haul the specific commodity. Having the right equipment that retains the most product and delivers the maximum payload will save you time and money.
Trinity trailers of all belt widths haul dry grain very well. Wider belts are recommended if you are hauling distillers grain (wet or dry), or other bulk products that aren't susceptible to bruising. The wider belt options also give you higher capacity, faster unload, and clean out products easier. We offer a variety of other customization options, including:
- Grain funnel for easier unloading into an auger or pit (not required for a narrow belt)
- Optional grain door for grain sampling
- High side liners for cleaner unloading
- Remote options for facilities with strict cross-contamination policies
- Special option chain bar inserts to keep grain from building up
