SUBSTANCE: invention relates to pontoon-ferry craft designed for crossing water basins. Pontoon link is lowered by guides in folded state. When link exits the guide extreme pontoons 1, 2 turn on axles 3, 4 due to a moment developed by pontoon weight force applied to its center of gravity. Engaged by extreme pontoons cables 10 actuate pyrocartridges, as a result, pressure increases in chambers 9 pulling apart pontoons 5, 6 tightened by cord 8 and creates in the last one a large stress, which leads to its destruction. As a result chambers 9 fastly increase in volume under pressure of combustion products, which leads to turn of pontoons 5, 6 about axis 7 and increase of angle between them. At drop in water immersion of ends of pontoons near chambers 9 is decelerated by earlier action of buoyancy force on them, the other ends move faster, which results in closing of ends of middle pontoons with each other and with the ends of extreme pontoons. Locks 11 are automatically closed and pontoon-bridge link is ready for operation immediately after its discharge into water.
EFFECT: technical result consists is faster passage of water basins and less labour force required providing the possibility of river crossing at high flow rate and improved operational characteristics.
