Abstract

A selectively arrangeable pallet for supporting conventional and unconventional loads and for reducing shock and vibrations on the loads. The selectively arrangeable pallet includes a base and a tray. The base and tray are selectively arrangeable in an overlaying relationship relative to each other in a nested configuration and alternatively in an expanded configuration. The tray is capable of being inverted relative to the base into the nested configuration to permit a first load-bearing surface of the tray to support the conventional loads and into the expanded configuration to permit a second load-bearing surface to support the unconventional loads. The second load-bearing surface of the tray includes a plurality of relatively spaced support pads for reducing shock and vibration. The support pads correspond with a plurality of relatively spaced recess in an upper surface of the base. The recesses extend through the upper surface of the base down into a plurality of relatively spaced support blocks extending from a lower surface of the base. The support blocks also reduce shock and vibration. In the nested configuration, the support pads nest within the recesses and, in the expanded position, the support pads support the unconventional loads.
