Abstract
Improvements introduced in the lifeboat davits, characterized in that the davits are provided on their upper part with a crosspiece that is part of a deformable parallelogram that forces it to always remain in a horizontal position as presented in the first modality or by the bracing of two cables that have the same effect, as presented in the second modality, whose mission is that the four strips of the lowering rigs form two isosceles triangles that prevent the transverse pendulum movement when the boat is suspended, characterized in that the position of the pivot axes of the davits is located in the vicinity of the trancanil so that when tilting, the boat is separated from the side as much as possible, characterized in that the boat's riding chute is divided into two wedge-shaped pieces and the upper piece accompanies the boat in its outgoing movement, since the four strips of the Tackles have their fixed mooring points in said riding area and not in the bow and stern of the boat, characterized in that when undoing the lashings that fix the boat, it is completely unhinged and cradled in the upper part of the riding arena, characterized in that the rigging strips of lowering have their returns driven by the sides of the davits, in such a way that the length of the cable of each strip does not undergo any variation whatever the angle of inclination of the davits, characterized in that when lowering the boat and making contact with the water, the riding arena continues to descend, submerging to the limit allowed by the four strips, and the boat will float without releasing any safety hook.
