Abstract: An air-cushion supported, manually manoeuverable, load-carrying apparatus including a load-carrying base, a dependent perimetric skirt for laterally confining pressurized air, and a member for restraining a foot portion of the skirt to a permanently inwardly extending configuration so as to be urged into sealing engagement with the ground by the internal air pressure during operation. The skirt restraining member is secured to the skirt at spaced inner and outer regions, spanning the foot portion. The rectilinear spacing is substantially less than the corresponding width of the foot portion so as to provide the foot portion with freedom to seal with the ground.
