Shipment Specs
Open deck trailers (flatbeds, step-decks, RGNs) are used to ship oversized, heavy, or irregularly shaped freight like heavy machinery (bulldozers, cranes, excavators), construction materials (steel beams, lumber, pipes), agricultural equipment (tractors, combines), wind turbine blades, and large industrial components, requiring securements like straps, chains, and tarps for protection and safety during transport. Examples range from moving farm tractors on flatbeds to driving massive cranes onto RGNs .
