Abstract
A method and a device for pivoting an accommodation ladder from a stowing position on a ship's deck to an active position outside the ship's side by means of at least one davit (17) and a pulley (21) for the operating wire (22) of the ladder, said pulley being pivotably mounted at the davit. The pulley is pivoted between two positions admitting the center of gravity of one ladder to pass the vertical line through the pivot axle (14) of the ladder when the ladder by means of the operating wire (22) is pivoted from stowing and active position resp. The pivoting of the pulley (21) is achieved by means of a member (27), e.g. a wire transmitting a pull to the pulley caused by the weight of the ladder during the downward movement thereof.
