<p>The gangway structure provides a connecting link between a vessel and a docking area to permit loading and unloading of the vessel. The prevalent variable relative positional dispositions of the vessel and docking area due to tidal and water current changes or vessel displacement changes caused by loading, are absorbed. A gangway structure can support one end of the vessel. The other end is held on the docking area. Cooperating vertical pivots and horizontal axis rollers preclude the torsional twisting of the gangway structure, e.g., in any position of movement in connecting link relation to the vessel and docking area. Tower structures and elevated connecting gangway span supports extending between for accommodating the docking area end of the gangway structure.</p> |
