ABSTRACT:
A cable reel comprising a drum and side flanges molded of plastic is of sufficient size, strength and rigidity to carry loads in excess of 10,000 lbs. without significant distortion or flattening. The required strength and rigidity are achieved by molding the side flanges so that they tend to assume a dished configuration that is substantially flattened when the side flanges are bolted by tie-rods to the ends of the drum all of which prestresses the side flanges. The tie rods have threaded ends for receiving bolts that secure the side flanges to the drum and serve to reinforce the final structure. During curing of each reel component while it is still in the mold, shrinkage of the component is resisted so as to increase the strength of the component. The drum comprises at least two sections and the reel may be easily disassembled and the parts stacked for storage and shipment as a compact package. The reel components are preferably molded of recycled plastic comprising a mixture of high density and low density polyethylene derived from post-consumer plastic waste.
