<p>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. </p> |
