A Grain Hopper is designed for Transportation of grain crops by road. Load 20-50 tonnes A grain hopper trailer is a trailer often pulled by a semi-tractor and used to haul bulk commodity products, such as grain. These trailers are used extensively to transport agricultural products as well as any other commodity that can be hauled in bulk (bulk goods) and loaded and unloaded through the trailer. Grain hopper or hopper-bottom trailers typically feature a rolling tarp on the top of the trailer, to enable easy loading of the product to be transported, and also offer protection during transport. They utilize two hoppers on the base of the trailer to unload to product, one servicing the rear half of the trailer, the other the front half. The output of these hoppers is usually controlled by a sliding plate on the base of the hopper, controlled by a user-operated crank handle. They also often have a dump body design for easy unloading.
