With folding pontoons 2 are connected by hinges 16 and 17 rotating in the vertical plane of the fairing 18 and 19. A similar design to the fairing 20 is fitted in the forward part of the housing 1. In the spaces between the sides of the housing 1 and the hinged sides of the pontoons 2 posted by nasal 21 and feed 22 hard floats, turning on vertical axes 23 and 24 relative to the folding of the pontoons 2. Hard floats 21 and 22 attached with the hinge 25 and the rolling pin 26 fairings 27 and 28. Between the nasal and feed hard floats posted pivotally attached to the lower planes catwalks 7 folding floats 29, made for example in the form of a flat hinge interconnected panels 30, forming a hollow chamber 31 of rectangular cross-section with a flexible seal 32 of the hinges 33 connecting panel. Motor link in the folded position is transported by land on tracked or wheeled vehicle. The rotation of the folding of the pontoons relative to the body is the vehicle through mechanisms made, nopromttosaveini system with a winch driven by a propulsion engine link or vehicle.

The proposed device operates as follows.

The vehicle with the engine link is served back to the water's edge, pre-connecting cables 34 hinged pontoons 2 and catwalks 7. Next, with the help of hydraulic cylinders or winches turn hinged pontoons 2 relative to the housing 1 on the 90o. While the cables 34 will rotate catwalks 7 with attached hinged foldable floats 29. After the transition of the centers of gravity of bridges and floats for the hinges 8 folding floats will begin to open under the action of gravity catwalks and folding floats to fall in the space between the sides of the housing 1 and the hinged sides of the pontoons 2. When this torsion rollers 10 will provide unstressed lowering catwalks hinged on the pontoons. In this position catwalks fix retractable pins 9 and unload the link with the vehicle on water. Next, in the space between the sides of the housing 1 and the hinged sides of the pontoons 2 get hard floats 21 and 22 by turning them relative to the axis 23 and 24 180o. Then fairings 18, 19, 20, 27 and 28 rotate relative to the axes 16 and 17 in the upper position and fix the movable pins is the ultrasonic inspection techniques. If the motor element is used as the tow vehicle on the bridge and ferry crossings, ramps into position do not translate. When this motor element connected to the pontoon links in floating bridges and ferries using forks 11 with movable pins and lugs 12 with a similar design to butt sites on the pontoon boat links. The translation engine link in the transport position is carried out in reverse order. When first using ramps and rope 35 turn catwalks with attached canopy floats 180ofolding and shift the floats to the median plane of the motor unit. Next put the fairings down, and hard floats 21 and 22 rotate 180o. After that load motor link on the vehicle and turn the hinged pontoons in the upper position.
