Abstract
An apparatus installed on board any maritime support for hoisting and handling loads at sea, the apparatus having at least one winch on which a cable is wound that enables the load to be raised, a gantry carrying suspension systems for the cable, and enabling the cable together with the load to be moved overboard relative to an edge of the maritime support in order to launch the load, and any fixed guidance and deflection systems close to the edge of the support and capable of receiving the cable after the launching and while the load is in use. The gantry is a fixed structure constituted by at least one continuous displacement system for a carriage carrying the cable suspension system and interconnecting at least two points, with a vertical line from one of the points passing through the support and a vertical line from the other support being overboard relative thereto, the two points defining a straight line segment that intersects at a point another straight line segment defined as interconnecting the winch and the guidance and deflection systems.
