A modular rotating carousel assembly for storage and unspooling of pipe or cable is provided that comprises a plurality of triangular subassemblies; each triangular subassembly comprises a base member and at least one pair of connecting members; the connecting members are connected together at one end to form an apex and are connected at the other end to the base member; the base members of the plurality of triangular subassemblies are rotatably connected together to form a first circle; wherein the apexes of the connecting members extend outwardly from said first circle; and a plurality of rotating caster members is positioned beneath the rotatable connection of a plurality of said base members. Additional sets of triangular subassemblies are built up on concentric circles until the desired size of carousel is formed. A drive mechanism is provided that includes a motor that rotates a perimeter drive chain that engages sprocket pads spaced about the circumference of the carousel. A modular hub is provided that includes a set of fixed plates arranged in a circle and a set of adjustable plates that are connected to the fixed plates. A set of segments forming a uniform circular shape is attached to the outside surface of the moveable plates and vertically oriented curved plates are positioned about the outer surface of the set of segments to provide a uniform surface for casters to rotate about.
