The invention relates to crossing-bridge means, and particularly to self-propelled ferries and can be used to ferry tanks and other heavy equipment over water obstacles.

Known motor link (see RF patent №2187441, 63 35/E 01 D 15/14, 21.12.2000, which includes a housing with a built-in deck roadway and deckhouse aft, the propulsion unit and propulsion and steering complex, accommodated in the housing, and connected to the housing of the folding pontoons with butt joints, and ramps on the outer sides. Folding pontoon is connected to the housing in the plane of the bottom hinge using the displacement of the panels, made in one piece with the bottoms of the pontoons, and in the plane of the deck - with catwalks. In the spaces between the hull sides and the hinged sides of the pontoons posted by rotating in a horizontal plane relative to the folding pontoon rigid bow and stern floats with fairings. Between these floats posted pivotally attached to the lower planes catwalks folding floats. Motor link is transported by land on wheeled or tracked vehicle in the folded position as bunk package, which is formed by reversal folding pontoon 90° and laying them on the deck of the hull to the left and to the right of felling. The rotation of the folding p is tonov relative to the body is the vehicle through mechanisms, performed, for example, in the form of a lever and cylinder.

The disadvantages of the known motor element are:

- the strength and rigidity of the hull pontoons small to allow the crossing of main battle tanks, the weight of which reaches 60 t;

- weak hinge nodes connecting the folding pontoon with motor, made in plain loops attached to the squares of the buildings of the pontoons may not be used for laying considerable dimensions and weight of the pontoons;

- the design of the link allows its installation in the transport position only in the form of a two-tier package with folding pontoons limited size, which limits the displacement, and therefore, the load capacity and reduces the possibility of using it as a self-crossing means for heavy equipment, including tanks;

- the complexity of the design leads to lower reliability, increases the intensity and time of preparation for the crossing of water obstacles and for transportation by land.

Famous ferry-bridge machine PMM-2M (see "Equipment and weapons", October 2001, p.11-12)), the most significant features adopted for the prototype for the proposed technical solution containing men and land tracked propulsion, hull and two folding is Antona, which in the transport position, placed the package on the case.

The disadvantages of the known ferry-bridge machines are:

- the presence of torsion beam suspension overland track Assembly while increasing the strength and rigidity of the machine housing makes it suitable for the crossing of heavy equipment, including tanks of previous generations (up to 42.5 t), but overestimates its own weight (36 t) afloat, including the land mass of the tracked propulsion and hull, limits the carrying capacity, which is insufficient for the crossing of the modern main battle tanks;

- levers revealing the mechanism of pontoons inscribed in the dimensions of the sides, to which their housing is made of vertical grooves that intersect the side stringers, reduce rigidity of the power of the frames of the pontoons and thereby weaken the construction of the ferry;

- there is a considerable gap between the casing and hinged pontoons requires the use of power catwalks, which complicates the design.

The present invention solves the problem of creating a landing ferry for crossing water obstacles main battle tanks and other heavy equipment.

Technical result achieved when solving a task, is to increase the capacity of the ferry at the expense of increasing the strength of eastcote its body at optimum weight and performance and increase reserve buoyancy folding pontoons.

The task is solved in that case each of the pontoons includes at least two connected by stringers with the formation of the bulk power frame samotnik frames, placed symmetrically with respect to the roadway and educated bilge and deck horizontal beams and rigidly associated side racks made on both sides of the motor pontoon and one adjacent Board each side of the folding pontoon, and stand on opposite sides of the motor pontoon is made uneven with ensuring the adjudication of the side pontoons at different levels when laying in the transport package in the upper parts of the uprights projecting above the decks, made the hinges connecting the motor housing with pontoon buildings lateral folding of the pontoons, and the walls of each of these counters below deck welded transverse ribs connected by a plate with the formation of box-like compartments, giving samotnie frame for more rigidity and employees to install the hinge cylinders disclosure mechanisms pontoons, while in the outer sides of the side pontoons on the bottom stringers made cavity for placement of the cylinders of disclosure mechanisms ramp, and along the bottom of the motor pontoon made guides projecting beyond the plane of the bottom, providing updat the additional stiffness and is used to communicate with roller devices specialized vehicles during the loading of the ferry and lowering it into the water.

Bottom beams samotnik frames motor pontoon in the region of the longitudinal axis in the form of vault used to install water jets propulsion and steering unit.

Bow and stern compartments of the side pontoons filled trudnoudalimymi material, such as expandable polystyrene.

Side vertical posts samotnik frames associated with the bottom deck and side stringers by means of vertical ribs.

Analysis of the main distinguishing characteristics showed that:

- inclusion in the body of each of the at least two pontoons connected by stringers with the formation of the bulk power frame samotnik frames, placed symmetrically with respect to the roadway and educated bilge and deck horizontal beams and rigidly associated side racks provided high strength and rigidity of the pontoons and ferries in General, it could be used for crossing water obstacles main battle tanks and other heavy equipment;

- welding on the walls of each of these counters below deck transverse ribs connected by a plate with the formation of box-like compartments, giving samotnie frame for more rigidity and employees to install the hinge cylinders disclosure mechanisms pontoons, the execution of the hinges connecting the pontoon is, on samotnik frames provided the necessary strength and rigidity of the pontoons in the places of maximum loads arising from the disclosure of the ferry in the working position and a folded transport;

- implementation of bottom beams samotnik frames motor pontoon in the region of the longitudinal axis in the form of vault used to install water jets propulsion and steering unit, helped to place them in the most efficient way to ensure good men qualities ferry;

- filling the bow and stern compartments of the side pontoons trudnoudalimymi material, such as expandable polystyrene, significantly increases buoyancy when receiving combat damage and cracks in the cladding;

- execution of the racks on opposite sides of the motor pontoon uneven provides the possibility of making the side pontoons at different levels and laying on the deck motor pontoon conversion ferry in a three-tiered package when it is translated from a deployed working position transport;

- performing the connection side uprights samotnik frames with bottom deck and side stringers by means of vertical ribs betrays power frame pontoons additional rigidity.

If necessary, ferry tanks or other heavy equipment vehicle 22 has mounted on ferry 1 extends to a water hazard and approaches the water's edge in forward motion. Ferry 1 is in the transport position into a three-tier package, the guides 23 interact with the roller devices 24 TRANS is Ortego means 22 and provide additional longitudinal rigidity of the entire package. Steam 1 by hydraulic cylinders 18 is translated into the working position in the form of a flat rectangular platform with open side pontoons 3 and 4, wherein the rack 12, 13, 14, 16 transmit transmit bending loads on rigid closed structure samotnik frames 6, 7, which it is perceived and through the bottom 8, deck 9 side stringers redistribute the entire bulk power frame, providing the necessary strength and rigidity. Then all the fastening elements ferry 1 on the vehicle 22 lastprivate, starts the movement and the sharp slow down when approaching the water's edge. Steam 1 due to forces of inertia slide guides 23 on the roller devices 24 of the vehicle 22 and goes down into the water. Steam 1 goes left or right side to prepared for loading a tank or other heavy equipment to place on the shore. On shore by means of hydraulic cylinders 19 are a few of the ramp 5, on which is loaded the ferry tank 1. Heavy loads (up to 60 t) affect the design of the power frame, the ramp 5 and hinges "on", connecting the pontoons 2, 3, 4. While the transverse ribs 16 plate 17 of the box-shaped compartments and vertical ribs 20 provide samotnie frame 6, 7, and the entire bulk power frame for more rigidity, providing the necessary strength and rigidity con is e.g. the case of the ferry, to preclude deformation.

After working on trafficking and assault equipment before loading on a specialized vehicle for transportation by land, ferry 1 is transferred from the working position to transport position, which with the help of hydraulic cylinders 19 of the folding pontoon 3, 4 by raznovideosti racks 12, 13 are placed in a three-tiered package on deck motor pontoon 2. Then ferry 1 using troublesho equipment (Fig. not shown) and the guide roller 23 to the device 24 is loaded on a specialized vehicle 22.

A rational distribution of water 21 propulsion and steering unit in the code "in the bottom of the beams 10 motor pontoon 2 provides good quality men ferry 1, and the bow and stern compartments of the side pontoons 3, 4, filled trudnoudalimymi material, significantly increase reserve buoyancy ferry 1 when you receive battle damage and cracks in the shell plating.
