The invention relates to crossing-bridge tools, and specifically to the ferries and pontoon bridges.Known transportable ferry pontoon Park chamber of Commerce the manual for engineer troops. Heavy pontoon Park chamber of Commerce. M Voenizdat, 1955), containing the pontoons and arranged on girders with deck boards.The disadvantages of the ferry are what for it is necessary to erect mooring personnel jetty on both sides, as well as the duration of the mooring ferry to the piers.For the closest analog adopted lag ferry, containing river links with ramps and pressure grid, each of which includes longitudinally spaced steel rope, with the ferry are, for its mooring to the shore requires additional calculation at least two people, and the mooring operation of the ferry, including the driving of anchors, pulling the ferry to the shore and anchoring mooring ropes, laborious and lengthy.The objective of the invention is the reduction of the maintenance calculation, complexity and time mooring ferry. The technical result is achieved by the fact that the known lag steam is supplied by means of motorisation, and each of these clamping nets pivotally attached to the end portion of the corresponding ramps, which are equipped with a lug spaced from the bottom end portion of the ramp, while above the transverse elements are in the form of steel cables.In Fig. 1 shows a lag ferry, plan, and Fig.2 ramps with anti-squeak grid plan; Fig.3 ramp, bottom view, and Fig.4 ramp, side view.Lag ferry provides a means of motorisation 1, river units 2 ramp 3 and clamping grids 4. At the end of the ramp 3 below set kassimeris the lugs 5. Pressure grid 4 is made of longitudinal and transverse steel ropes that are connected by clamps 6. Thus the longitudinal steel rope had 3. In the transport position, the presser grid 4 is fastened from below to the ramp with rail 9 with screws.The device operates as follows.The ramp 3 with the help of crane beams are mounted on the transom river units 2 in the working position. After this is removed, the rail 9 and the presser grid 4 is laid down (rotated 360about) on the roadway ramps 3. With the approach of the lag ferry to the shore ramps 3 are installed on the ground, and then laid before them (rotated 180about) clamping the grid 4. When loading the equipment on the ferry suspension when hitting the presser grid 4 captures the ferry in the initial position and provides a secure entrance to the ramp 3. Next, when entering vehicles on the ramp 3, the lug 5 is fixed steam in the original position to ensure the arrival of technique directly on steam. After loading the equipment on the ferry ramps 3, together with the presser grid 4 are placed on the river link 2. LAG FERRY, containing river links with ramps and pressure grid, each of which includes longitudinally spaced steel rope, United clamps with transverse elements, characterized in that it has among pareli, which is equipped with a lug spaced from the bottom end portion of the ramp, the transverse elements are in the form of steel cables.
