<p>The swing bridge (1) defined by a first bank (4) and by a second bank (6) on which there are tracts of road surface (24, 26) is constituted by a first mobile plane (2) restable, at its first end (21) on the said first bank (4) and is supported, at its other end (22) in proximity to the said second bank (6) with possibility of free rotation about its vertical axis (Z) passing through its own longitudinal axis of symmetry (Y) and defining by a vertical hinge pivot (5); the second end (22) of the said mobile plane (2) being hinged about its horizontal transversal axis (X) to the said hinge pivot (5) and having hinged to itself a connecting plane (7) of the mobile plane (2) with the second bank (6); between the mobile plane (2) and the connecting plane (7) there being envisaged movement organs (20) of the said connecting plane (7) and the mobile plane (2) bearing inferiorly at least one floating hollow body (8) with adjustable trim which raises or lowers the said first end (21) and nautical propulsion organs (9) which move the said mobile plane (2) in rotation about the said hinge pivot (5) after the said mobile plane (2) and the said connecting plane (7) have been raised from the said banks (4 and 6). <IMAGE></p> |
