Bulk cargo (solid dry bulk cargo) is a cargo of one type of material transported in large quantities and large batches. Bulk cargo can be divided into dry, liquid and special-purpose cargo. Bulk cargo is most often transported by sea, which does not exclude full-truck transport by inland waterway or rail.

Among dry bulk cargo (solid dry bulk cargo) we can distinguish: shapeless, powdered, granular, lumpy, granular materials and goods transported in pieces. Devices intended for mass transport have a reinforced structure and significantly greater efficiency.
