Abstract
A material mover includes substantially rectangular top and bottom sheets connected to perimeter sidewalls defining at least one chamber. The bottom sheet is perforated with orifices at least in a central portion and has a greater width than that of the top sheet at least in middle and lower regions of the top and bottom sheets. A plurality of partition members connect at least portions of the top and bottom sheets to one another within the chamber, extend parallel to lateral edges of the top and bottom sheets, and are spaced from the perimeter sidewalls. A fluid weir is defined along an outer periphery of the bottom sheet to provide a fluid film reservoir at least under the central portion of the bottom sheet including the orifices. Fluid in the fluid reservoir is substantially contained by the fluid weir.
