The invention relates to crossing-bridge means, and more specifically to the ferry.

Famous ferry with capacity of 40 tons pontoon-bridge Park PPM (see Instructions on the tow-motor boat is from jointly connected the two outer and two medium pontoons, tool automotive, made in the form of a tow-motor boats.

The disadvantages of the ferry are low speed ferry because of the great water resistance and insufficient capacity for crossing promising tanks.

Also known ferry (prototype - see application Germany 3045472 on CL 63 In 35/36, 1980 ), including wodoslawsky pontoon folding coastal and fluvial units, consisting of pivotally connected two outer and two medium pontoons, and placed between the links of the means of motorisation in the form of motor units with water jet.

The disadvantage of this ferry is the necessity of application of coastal units for loading and unloading equipment, as well as to improve the flow stream of the ferry during its movement in directions coincident with the longitudinal axis of the ferry. For large-capacity ferry (3-4 tank) this design decision is justified. However, for a ferry load on one tank the use of coastal links leads to inefficient use of the material part. However, the ferries designed to one terminal of the tank and dispersed on the water surface, less vulnerable than paramoreeee aimed at solving the problem of rational use of the material part of the ferries, intended primarily to one terminal of the tank.

The solution of the stated problem is achieved by the fact that the ferry, including wodoslawsky pontoon folding units, consisting of two outer and two medium pontoons equipped with the roadway, and placed between the parts of the tool automotive in the form of motor link with water jet, in his extreme ends of the pontoons of the links made with smooth contours, and at the middle pontoons are installed with the possibility of rotation about axes perpendicular to the longitudinal axis of the middle pontoons equal to the width of the wedge-shaped wodoslawsky the ramp, and in a rotated position of the bottom of the ramp to form smooth contours medium pontoons, and in the transport position - smooth surface of their decks.

Application of the proposed technical solution will allow a rational use of the material part of the ferry, designed primarily to one terminal of the tank, and thereby reduce the cost of the ferry to 50-60%.

The invention is illustrated by drawings, which depict: Fig. 1 - steam side view in Fig.2 - steam, plan, and Fig.3 - section a-a in Fig. 2: Fig.4 - placing the ramp in the transport Polo is>Steam includes wodoslawsky pontoon folding units 1 and 2 and is placed between the tool automotive, made in the form of motor element 3. Each pontoon link consists of two extreme 4 and two medium 5 pontoons interconnected by means of hinges 6, 7, 8 and deck locks 9, 10, made in the form of clamp. The ends of the ferry at the pontoons 4 is made with smooth contours, and at the middle pontoons 5 is installed with the possibility of rotation about axis 11 perpendicular to their longitudinal axes, wodoslawsky ramps 12 and 13, is made wedge-shaped and is equal to the width of the middle of the pontoons. In the rotated (operating) position the bottom of the ramp to form smooth contours medium pontoons, and in the transport position - smooth surface of their decks. Rotate the ramps to and from the transport position into the working position and back by using the ramp-beams 14 that are installed in a cylindrical shank in the socket on the deck at the pontoons. When the movement of the ferry ramps held by means of pins 15, nominated from niš on the bow at the pontoons into the slots on the ends of the ramps. In the transport position, the ramp-beams placed in the recesses 16 on the deck at the pontoons. Deck medium p is made in the form of a fork 17 with a rolling pin and ear 18, transport hook 19 and the bottom hooks 20, and the outer pontoons installed bracket 21. Motor link 3 includes wodoslawsky building, which housed the power plant and water jet propulsion. The deck of the hull is built roadway and cabin crew. On the hull sides installed butt sites on designs similar junction nodes of the link.

The proposed device operates as follows. Motor link and pontoon folding units unloaded from cars to water, pre-opening transport hooks 19. Under the action of gravity and backwater pontoon units are disclosed, then the maintenance calculation closes on each pontoon deck link locks 9, 10, lowers the hooks 20 in the bracket 21, summarizes the pontoon links to motor link from the sides and joins them together using the joint nodes 17 and 18 placed on the motor and pontoon units. Further calculations are removed from the NIS 16 ramp-beams 14, sets their cylindrical shank in the socket on the deck at pontoons, turns with their help, the ramp relative to the hinge 14 to water and wdiget pins 15 in the socket ramps. After this steam serves to the place of loading, push stirl-beams, vidvigayt pins 15 in the socket of the ramp and follow to the opposite shore. After the ferry crossing, ferry disassemble, put the pontoon units, load them in the engine link on cars.

Ferry, including wodoslawsky pontoon folding units, consisting of pivotally connected two outer and two medium pontoons equipped with the roadway, and placed between the parts of the tool automotive in the form of motor link with water jet, characterized in that it ends at the pontoons of the links made with smooth contours, and at the middle pontoons are installed with the possibility of rotation about axes perpendicular to the longitudinal axis of the middle pontoons equal to the width of the wedge-shaped wodoslawsky the ramp, and in a rotated position of the bottom of the ramp to form smooth contours medium pontoons, and in the transport position - smooth surface of their decks.
