<p>An articulating gangway having an elongated member forming a passageway and pivotally mounted on a supporting base for vertical swinging movement about a substantially horizontal axis and slewing about a vertical axis. A position control assembly is connected to the gangway for controlling the swinging movement of the member, with this control assembly having a slack take-up arrangement included therein for keeping a cable connected between a free end of the member and a suitable winch taut at all times in order to permit position changes of the gangway member, such as due to the change in tides, without actuation of the winch once the gangway member is lowered into an operative position. A gangway element can be pivotally attached to the outer end of the gangway member for permitting the terminal end of the passageway formed by the gangway to be in abutting relationship to the deck of a ship, and the like, with which the gangway is deployed regardless of the relative position of the base of the gangway to the ship. Wheels or rollers are advantageously provided on the outer portion of the gangway in order to permit the gangway to better meet changing deck conditions and pitch, while a stop can be disposed in the joint between the gangway member and the gangway element for permitting only downward swinging movement of the gangway element relative to the gangway member.</p> |
