FERRY

摘要

stream-crossing facilities; ferries. SUBSTANCE: ferry includes displacement pontoon collapsible units consisting of articulated two outer and two middle pontoons provided with roadway with motorization facility in form of motor unit with water-jet propulsors. Outer pontoon units have streamlined shape at ends. Wedge-shaped displacement ramps are mounted on middle for turn about axes perpendicular to longitudinal axes of middle pontoons; width of these ramps is equal to width of middle pontoons. In turned position, bottom of ramps form streamlined shapes of middle pontoons and in transportation position, they form even surface of their decks. EFFECT: enhanced efficiency of use of ferry materiel for ferrying one tank; reduction of ferry cost by 50 to 60%. 5 dwg
