Abstract (en)

Mobile boat hoist equipped with retractable longitudinal members comprising a pair of portal frames (1, 4, 5) spaced apart from one another, a track connected to the top of each frame and a spacer crossbeam (6) connecting the frames. At least one lifting trolley (10) can slide on said track, a retractable longitudinal member (8) is hinged along a horizontal axis near an upper end of each frame and comprises a track. Hinged and collapsible stiffening devices comprising connecting struts and tie rods are arranged between each longitudinal member and the frame. The retractable longitudinal member (8) is hinged so as to rotate from a first raised/near/adjacent position with respect to the upper longitudinal member (5) to a second extended position and in continuation of the upper longitudinal member (5), in alignment with the track of one or more lifting trolleys (10), creating an extended track extending from each upper longitudinal member (5) to the retractable longitudinal member (8).
