The invention relates to crossing-bridge means, and more specifically to the ferry.Known self-propelled ferry PMM-2 (Technical description and user manual self-propelled LASS="ptx2">The disadvantages of self-propelled ferry PMM-2 are small carrying capacity and stability, as well as a large sediment (1.8 m).Also known 40-ton ferry pontoon-bridge Park RAP (prototype - instructions for tow-motor boat-the pusher-BMK-So - M: Voenizdat, 1970, S. 73), containing two displacement pontoon river level, consisting of pivotally connected two outer and two medium pontoons fitted on the transom butt joints, tool automotive in the form of a tow-motor boats and ramps installed at both ends of the ferry.The disadvantages of this ferry are low capacity and lack of stability due to the small area of the cargo waterline. In addition, the steam can not move the Shuttle in the direction of the longitudinal axis of the ferry) from shore to shore and after each otchalivai from the banks need to deploy, which takes a considerable part of the time of his flight.The proposed invention is directed to solving the problems of increasing capacity and improving stability of the ferry, as well as reducing the time of his flight.The solution of the stated problem is achieved by the fact that the Shuttle ferry tank, and the soda is their pontoons, fitted on the transom butt joints, tool, automotive and installed on the ends of the ferry ramp as a means of motorization applied motor link with two hinged pontoons, to the outer sides of which docked the boat extra long river sections, the outer transom which is made with toboggan lines, while on the outer transom at each pontoon both long river of the links has a folding hard bulwark, which is a continuation of the sliding rim, and between the ramps installed removable gunwale, made of waterproof cloth.Application of the proposed technical solution will allow a 1.5 fold increase capacity and improve the sustainability of the ferry by increasing the area of the cargo waterline 1.6 times, while also reducing the time of his flight by 10-15% compared to the prototype.The invention is illustrated by drawings, which depict: Fig. 1 - General view of the Shuttle tank ferry, plan, and Fig.2 - the same, lateral view; Fig.3 - the same, front view; Fig.4 - removable bulwarks, front view; Fig.5 - folding rigid skirting, side view.Shuttle tank vapor contains two elongated photosmash the Ponto the entrance ramps 4 and 5. Each river link 1 and 2 consists of an interconnected by means of two hinges at 6 and two medium 7 pontoons. In the deck of river links embedded roadway. Each river link with one end has a vertical transom, and the other (outer) end of the transom is made in the form of sliding rim. On vertical transom medium pontoons made butt nodes that can be used to connect the river links with the engine management: on one pontoon fork with a rolling pin, and the other ear. By sliding contours on the transom at each pontoon has a folding hard bulwark 8 connected therewith by means of hinges 9. In the tilted position the bulwark is retained by the spacer 10. Between ramps 4 and 5 are removable gunwale 11, made of waterproof fabric. Lifting, holding and lowering of the ramp 4 and 5 is carried out using a crane beams 12 and 13 installed in a cylindrical shanks in glasses built into the deck at the pontoons. Motor element 3 consists of a housing 14 and a hinge connecting the two hinged pontoons 15 and 16. On the outer sides of the folding pontoons installed butt sites, similar in design junction nodes on the transom medium Pontigny pontoons built roadway. Operating a motor link is from cuttings. In the folded position of the motor element and river links carried on pontoon hire.The proposed device operates as follows. Pontoon motor vehicles with link river and links come to the water's edge and unload parts water. Motor link pontoons before unloading throw back. After disclosure of the river parts of their outer and middle pontoons interconnected with the butt of deck and bottom locks down these links to motor link and connect with joint nodes. Then the calculation of the ferry pulls out of the niches located on the deck at pontoons, crane beams 12, 13 and set their cylindrical shanks in the glasses on the deck at the pontoons. Next, using the crane beams are removed from the niches on the deck at pontoon ramps 4, 5, and hang them on the transom medium pontoons 7 at the ends of the ferry. Holding the ramp in the raised position, set between the gunwale 11. Then raise into position hard gunwale 8 and fix their spacers 10. After this steam serves to bridge loading tanks, lowered the ramp on the shore, download tank on steam and without u-turns to follow p is burned after unloading the tank is lifted up steam without u-turns should be to the original shore for loading the next tank. At the end of ferry tanks the gunwale 11 of the waterproof fabric is removed, the ramp and the crane is placed in a niche on the deck at pontoons, hard gunwale 8 is transferred to the transport position, disassemble the ferry on the links, put them and load on the pontoon hire. Shuttle tank vapor that contains two displacement pontoon river level, consisting of pivotally connected two outer and two medium pontoons fitted on the transom butt joints, tool, automotive and installed on the ends of the ferry ramps, characterized in that as a means of motorization applied motor link with two hinged pontoons, to the outer sides of which docked the boat extra long river sections, the outer transom which is made with toboggan lines, while on the outer transom at each pontoon both long river of the links has a folding hard bulwark, which is a continuation of the sliding rim, and between the ramps installed removable gunwale, made of waterproof fabric.
FIELD: bridge crossing equipment; self-propelled ferries; crossing of heavy equipment through river barriers.
SUBSTANCE: proposed ferry is self-propelled in water and may be transported by land in form of stack and launched into water by means of specialized vehicle. Ferry is provided with deployment mechanisms which are articulated together and are equipped with roadway built in decks, central propulsion pontoon and side hinged pontoons whose roadways are inclined relative to horizontal deck forming recesses for stowage of ramps. Hull of each pontoon has at least two frame rings interconnected by means of stringers, thus forming solid load-bearing skeleton, frame rings located symmetrically relative to roadway and formed by bottom beams and deck horizontal beams and rigidly connected with them by means of side pillars provided on both sides of propulsion pontoon and on one adjacent side of each side hinged pontoon. Pillars of opposite sides of propulsion pontoon have different height for placing the side pontoons at different levels in stowing them in three-tier stack. Upper parts of pillars extending over deck are provided with hinges connecting the propulsion pontoon hull with hulls of side hinged pontoons; wall of each pillar has transversal stiffeners mounted under deck and connected by means of plate for forming box-shaped compartments imparting additional rigidity to frame rings; they are used for articulated mounting of hydraulic cylinders of pontoon deployment mechanism. Outer sides of side pontoons are provided with cavities above bottom stringers for placing the hydraulic cylinders of pontoon deployment mechanisms. Made along propulsion pontoon bottom are guides projecting beyond bottom plane, thus forming additional rigidity; they are used for interaction with roller units of the specialized vehicle in loading the pontoon and launching it into water.
EFFECT: enhanced reliability of ferry.

SUBSTANCE: proposed ferry may be transported by land and may be launched into water by means of specialized vehicle. It is provided with deployment mechanisms articulated together and equipped with roadway built in decks, central propulsion pontoon and side hinged pontoons, deck house with control members, engine with its systems and propulsion and steering complex mounted in propulsion pontoons, fore and aft fairings with wash plates and swivel ramps mounted on side pontoons. Pontoons have similar displacement; they are divided into watertight compartments by means of bulkheads. Each ramp is made in form of watertight displacement-type skeleton imparting additional transversal stability to ferry during embarkation of tanks which may be locked in any position on hinged pontoon within preset angles of turn. Fore and aft deck parts of propulsion pontoon are extended beyond fore and aft transoms of side pontoons for position of fore superstructure on the extended parts together with built-in deckhouse and aft superstructure and laying the side pontoons between superstructures, thus transforming the ferry into three-tier stack when it is returned from deployed position to stowed position. Fuel tanks of engine supply system are arranged in middle compartment of central propulsion pontoon; they are arranged in groups located symmetrically relative to center of mass of ferry; each of them is provided with service tank fitted with fuel-contents gage and interconnected by means of pipe lines for centralized refueling through filler neck located in fore superstructure, thus ensuring smooth consumption of fuel from tanks both through service tanks and through one of them; provision is made for disconnection of group of tanks in case of damage to one of them with the aid of electric two-way valves. Propulsion and steering complex includes radial-type water-jet propellers at varying thrust vector; water-jet propellers are provided with vacuum pumps which are so mounted that air may be evacuated from water-jet propeller trunks which are filled with water before switching-on the pumps. Pumps may be switched on/off both automatically and manually from control console mounted in deckhouse.
