Accommodation ladder having a first flight of steps of adjustable length with one end adapted for connection to a ship while its opposite end is pivotably mounted about a horizontal axis at a given level above the quayside. This flight of steps is also mounted for pivotal movement about a vertical axis passing between its opposite ends at a location substantially spaced from its horizontal pivotal axis. A second flight of steps is adapted for mounting at one end adjacent the quayside to pivot about the vertical axis and extends upwardly from this mounting to interconnect with the first flight of steps enabling joint pivoting with the latter about this axis. |
