    A ship's embarkation device and comprises a projecting means, e.g. a ladder (3), which atone end is pivotally connected to a first platform (2), which is pivotally connected to the ship's deck, and at its other end is pivotally connected to a second platform (4). The first and second platforms are unrotatably connected to each other via a connecting bar (5), which is pivotally arranged at both platforms. The connecting bar always keeps the second platform in a horizontal position as well as strengthens the torsional resistance of the device. Moreover the ladder is kept tighter to the ship's deck, which prevents the ladder from swinging as the ship is rolling.

    The ship’s sideboard ladder is known, containing a march that is pivotally connected at one end with an upper platform, which is movably mounted relative to the deck of the vessel, and the other end is connected with the lower one, and a lifting device, block and brace, and a lifting cable. a vertical plane relative to the upper platform, and the lifting cable is stored on the block and associated with the bracket 1.
    However, such a ship's ladder is characterized by low reliability.
    The purpose of the invention is to improve the reliability of the ship's sidewalk.
    The goal is achieved by the fact that the ship's side ramp is equipped with a rigid connecting beam and a limiting device, and the lifting cable of the launching device is connected to the lower platform while the connecting beam is hinged: in one end with the upper platform, and the other end with the lower platform and is parallel to the longitudinal axis of the march.
    In addition, the axes of the hinges for fastening the connecting beam and, respectively, the hinges for turning the upper and lower platforms are located in different vertical planes.
    The axes of the hinges of attachment of the connecting beam and the pivot points of the upper and lower platforms can
    be located in the same vertical planes.
    The connecting beam can be located in the same plane with the 5th march, from the side of its inner side edge.
    The connecting beam can be located in the vertical longitudinal plane of symmetry of the march and
    o under it.
    The upper deck is connected to the deck of the vessel by means of straight guide grooves and is movable in a plane,
    5 perpendicular to the median plane of the vessel.
    The bottom platform contains a cantilever lever and two pulleys, while the cantilever lever is fixed on the
    0 adjacent to the vessel is the lateral edge of the lower platform, is parallel to it and faces the cantilever end towards the upper platform, one of the pulleys is mounted on the cantilever
    5 end of the lever, and the other - on the outer corner of the end of the lower platform, and on the pulleys of the stocks lifting cable.
    The bottom platform may contain a roller, the limiting device is made in the form of a curvilinear guide, and the lifting device bracket is fixed on the end of the lower platform, while the roller is mounted on the inner side edge of the lower platform, and the curvilinear guide is installed on the edge of the ship, facing working surface toward the bead and configured to mate with the roller of the lower platform. The lowering device contains the boom, the block, bracket and limiting device are mounted on the bracket, and the lifting cable is attached to the bracket by means of a restrictive device. Figure 1 schematically shows the proposed ladder, a view in plan; figure 2 is the same, side view; in FIG. 3 - the same, with a device for carrying the ladder overboard, in a perspective view; in fig. - ship side ladder, made according to the second variant, side view; figure 5 is the same in the plan; figure 6 - ship side ladder, made according to the third option, a view in the plan; 7 - the same, side view; in fig. 8 - the same, in the position of marching, view with. side of the end of the ladder; in Fig. 9, the platform of the ladder is shown in the perspective view of an option). Ship side gangway is mounted on the deck of 1 vessel. The top plane 2 is attached pivotally to deck L by means of a hinge 3. A ramp is connected at one end to platform 2 by means of hinges 5. The lower platform 6 is hinged to the opposite end of the march by means of a hinge 7. The platforms 2 and 6 are connected by a hinge to the connecting beam 8, which has the ability to pivot on the hinges 9 and, 10, with the result that both platforms are always held parallel to each other, i.e. horizontally, at any position of the ladder. The connecting beam 8 senses the twisting forces that occur between platforms 2 and 6 when the ladder is turned into and out of the folded position. To the square 6, a lever P is attached, protruding behind it, and this lever is located along the march from the inside. The gangway is held by a lifting troso 12, which is wound on the winch 13 through a block} k mounted above the deck, for example, on the upper deck mast or on another similar vessel structure, and stored on the pulley 15, mounted on the outer corner of the lower platform 6, on the pulley 16, mounted on the inner corner of the pad 6, and on the pulley 17 mounted on the free end of the lever 11, and attached to the bracket 18 on the decks 1. Winch 13 contains only one drum. The axes of the hinges 9 and 10 of the coupling 8 and the axis of the hinges 5 and 7, respectively, of the axles 2 and the lower 6 areas are located in different vertical planes. In Fig. 1, solid lines show the gangway in a raised position, and dash-dotted lines in the lowered one. - According to FIG. 1, the plane A passing through the axes. the hinges 9 and 5 are actually parallel to the plane passing through the axes of the hinges 10 and 7. This is valid for any position of the ramp. In addition, the distance C between the axes of the hinges 9 and 5 is equal to the distance D between the axes of the hinges 10 and 7. In accordance with FIGS. 4 and 5, where the second embodiment of the invention is shown, it is possible to lift the ladder to a position above the deck of the ship , which may be desirable in ports where there are significant differences in water levels at high tides and low tides, and in cases where the vessel is loaded so that the deck level is lower than the berth level. In accordance with this option, the anchorage bracket 18 is fixed above deck 1 on that the same level as the block T, and the connecting beam 8 is installed at a greater distance from the march than in the first embodiment, for the passage of the cable between the march k and the connecting beam 8. The axes of the hinges 9 and 1U of the connecting beam 8 are located in vertical planes and, respectively, passing through the axes of the hinges 5 and 7 of the upper and lower ramps in order to make it possible. raising and lowering the ladder relative to deck 1. In FIG. solid lines show the ladder in a horizontal position on the deck of the vessel, and the dash line shows the ladder when it is raised to a position above the deck or lowered to a position below the level of the deck. In the embodiment of the invention shown in FIG. 3, an outrigger boom 19 is provided, at its free end a block 20 is installed. gangway when it is raised to horizontal
    position. Instead of the hook 21, another locking element can be attached to the boom 19.
    The embodiment that is illustrated in Figs. 6-8 is intended for small vessels and therefore its design is somewhat upscale in comparison with opkannyh options. The connecting beam 8 is located under the march and is preferably made in the form of a pipe, which is provided at both ends with tubular elements 22 arranged perpendicular to its axis, which with the help of discs 23 are connected with the possibility of rotation to platforms 2 and b through the axes of hinges respectively 9 and 10 By using such a construction, the connecting beam can transmit twisting forces, which is necessary when the ladder is turning e and from its folded position on the deck of the vessel.
    A lever 2A is installed on the side of the platform 6 facing the ship's side; on the free end of the second there is a roller 25 configured to mate with a guide 26 having a curviline section 27 in the upper suit. A bracket 28 is located above the guide.
    The ka of FIG. 9 depicts a variant of installation of the top platform 2 of the ramp in the straight guide grooves 29, which are made on deck 1.
    The ship's ladder is used as follows.
    When the ladder is raised, when the latter is raised so that the pulley 17 reaches the cru (and 21 or clevis 18, its march and both platforms turn to the vertical or folded position due to the fact that the shkiv 17 and the platform 6 are held in place by the beam 8 while the outer side of the platform 6 continues to rise. The rotary movement of the platform 6 lifted in this way is transmitted to the platform 2 through the connecting beam 8. Thanks to this design, the ladder can be carried overboard the vessel by pulling out the boom 19. This can be not bhodimym in the case when the vehicle does not fit close to the dock, for example, in connection with the presence of fenders installed on the quay.
    In the embodiment corresponding to Fig. 9, the ladder is folded in a different way. In this case, parallel movement of the ladder occurs from the position outside deck 1 to the position on the deck and vice versa. This may be necessary in cases where the deck is below the berth and the ship’s side is so close to the berth that it is not possible to place a gangway between the ship and the berth. In this case, the ladder can be raised from the position it occupies on the deck. Such parallel movement is carried out by displacing the upper platform 2 on the deck in the guide grooves 29. When the ramp is made according to the variant shown in FIGS. 6-8, roller 25 abuts the side of the ship, and when platform 6 reaches the level of deck 1 of the ship, roller 25 rolls along guide 26, in the upper part of which there is a curvilinear section 27, gripping roller 25. On the latter, with further selection of cable 12, the ladder turns around hinges 3 and assumes the vertical position shown in fig. In this position, the ladder rests on the upper part of the bracket 28.
    To descend the ladder, the cable 12 is released, after which it sags, as a result the ladder is lowered. ----- I XX / r / VV / VX / VX / yVX - / 7 // / / /.., J 5} I I IB K 7 Yu W // x / y / vx / w X
