A ship's accomodation ladder pivotally connected to the deck of the ship and has a platform (8) pivotally connected to the free end thereof and being supported by a wire arrangement (9, 10) by means of which the platform may be raised and lowered together with the ladder. The ladder is of telescopic type and consists of an upper portion (6) and a portion (7) which is telescopically displaceable relative to said upper portion and to which the platform is connected. A support wire (21) of a fixed length supports the ladder and controls the displacement of the moveable portion (7) relative to the upper portion (6). At least one of the wires (9, 10) supporting the platform (8) extends via the upper portion (7) of the ladder in order that the expansion and contraction of the ladder shall be well coordinated with the raising and lowering of the platform. |
