Abstract: The cargo system secures at least one steel coil for transport on a flatbed carrier. Each coil sits on movable cargo supports coupled on top of a base with support beams. Support brackets couple the support beams to anchoring beams that are coupled to the flatbed carrier. Once a coil is loaded, arms with adjacent upper and lower segments connected by cross members pivot on arm mounts to make contact with the coil. The arms adjust by lengthening or shortening based on the size of the coil. Tethers pass through anchor brackets and over the coil to hold the coil to the base. The arms apply pressure to the coil based on the tension of tethers that extend from the ends of the arms and couple to tethering brackets coupled to the frame of the carrier.
