Abstract
A trailer for transporting granular material, such as sand or proppant, has a purpose-built shape, and loading and unloading hatches at top and bottom. The trailer includes a hollow vessel for holding granular material. The vessel is enclosed with top and bottom hatches. The vessel has a tapered lower section and a domed upper section, allowing bulk material to be piled and concentrated horizontally below and above the hatches. A chassis extends fore and aft of the vessel, and potentially through an interior of the vessel. The chassis may extend upward from a wheeled section so as to pass through a vertically central part of the vessel. The chassis may also act as a trailer suspension system. The vessel may be made of aluminium and mounted to the steel chassis.
