Abstract
An air-lift vehicle has inner and outer multi-lobed peripheral skirts arranged so that the corresponding lobes of the skirts are in register. Means is provided to supply compressed air to the inside of the inner skirt and between the inner and outer skirts for lifting purposes. The space between the skirts comprises a plurality of compartments each defined by two corresponding lobes of the inner and outer skirts. The lower edges of the lobes of the outer skirt at least are located in the same horizontal plane as a result of which the height of lift and the stability of the vehicle are improved.
