Abstract
A pull sheet pallet is provided and is adapted to be placed on a flat support surface for loading cargo thereon so that the cargo can be moved. The pallet comprises a sheet of material which is formed to have a plurality of nub structures thereon so that a plurality of protrusions extend upwardly from an upper surface of the material and a plurality of concavities are formed into a lower surface of the material. The sheet pallet is constructed of a stiff yet pliable material such that, when cargo is loaded onto the upper surface, contacted ones of the nub structures operate to collapse thereby forming a plurality of course regions on the upper surface which inhibit lateral sliding movement of the cargo on and across the upper surface when the cargo is acted upon by a force. Uncontacted ones of the nub structures form a raised barrier which operates to resist lateral movement of the sliding cargo. A lip may be disposed along a peripheral edge of the sheet of material.
