Flexure-compensating device for flexible pallets supporting very heavy loads

摘要

For preventing sidewise slippage of very heavy loads being supported on the load-bearing surface of a flexible pallet, upward projections from the surface are provided. The projections are suitably sized, disposed so as to compensate for downward movement of the load- bearing surface caused by flexing of the pallet, as occurs with plastic pallets, and additionally provide lateral resistance to sidewise slippage of the load. The projections are preferably molded integrally with the surface and may be shaped as stripwise ledges and ramps, rows of isolated knobs, studs, or pyramids, for example, or serrated strips. The projections may be covered with a friction-enhancing covering, particularly if integrally molded, or may be elastomeric and capable of forming a retaining wall for the load that can be useful for a pallet loaded beyond its elastic strain limit.
