Abstract
A one piece plastic cradle pallet is provided to enable the loading and transportation of coils of heavy steel or other metal in a vertical position. The cradle pallet is designed to nest with identical cradle pallets, in such a manner as to allow banding of a number of cradle pallets for ease of return shipment. Supporting legs are spaced apart, in such a fashion, as to allow two way entry of various lifting and handling device blades. Two safety walls are located on the outside top surface of the pallet, to provide added protection for personnel during loading and unloading procedures. The cradle pallet is manufactured by producing a steel or aluminum mold whose dimensions will allow for part shrinkage to the correct design dimensions. The mold is then used in the known art of rotational molding pV to produce an enclosed plastic hollow shaped cradle pallet. The hollow pallet is then encased in a steel fixture and filled in a separate known process with semi-rigid plastic foam. The finished cradle pallet can be of any color with molded in graphics for identification purposes. The pallet is UV (ultra-violet) stabilized to prevent deterioration from sunlight and can be utilized in t…
