FIELD: transport. ^ SUBSTANCE: invention relates to ship building, particularly, to amphibious ships. Proposed device comprises housing with bulk separation platform, front and/or rear drive drums whereon fitted is elastic bearing closed belt with air floats across platform outer horizontal surface. It comprises also closed chamber between platform bottom surface and belt bottom flight that makes sealed air cushion communicated via air duct with air blower. Besides it includes closed chamber guard made up of flat walls closing gaps between belt flights and platform topl and bottom surfaces. It incorporates propellant engine articulated with front and/or rear drive drum. Belt side edges are conjugated with flat walls of bottom closed chamber side guards. Aforesaid drums are arranged between said guards. Platform is jointed with aforesaid flat inner walls of guards and articulated with drive drums. Platform is divided into watertight compartments to house engine, drum transmission and air blower. Air float inside pressure is lower than air pressure in closed air cushion below bottom closed chamber. Platform bottom surface is located above top envelop of belt operating shape. Side guards have skids with their level located not lower than horizontal tangent to circle arc of belt idle shape corresponding to its position without contact with support medium. Height of air floats resting on soil is set to provide for required clearance of skids with belt bottom support flight located between top and bottom envelopes. ^ EFFECT: higher reliability and efficiency. ^ 4 cl, 10 dwg |
