Definitions

• Present invention relates to an arrangement for evacuation of persons from a ship, especially from passenger ships of the "express boat” type, ferries or the like, where the evacuation arrangement is arranged substantially at deck height.
• the arrangement is characterised in that a hatch member, which is inlaid in a side of the ship and which is pivotally mounted about a lower substantially horizontal axis arranged approximately at the level of the deck of the ship, is swingable from an inactive position in the side of the ship to an active use position outside the side of the ship by means of power-driven swinging mechanisms, and that the gangway forms carrier means for a raft package fastened in this, which is readily read- justable from an inactive storage position internally in the ship to an active use position endways outside the gangway.
• the evacuation arrange ⁇ ment can be handled in the easily controllable manner intended, in an inactive storage condition as well as in an active use condition and also in the readjustment phase between the storage and the use phase.
• the hatch member forms carrier means for a telescopically outwardly movable gangway, the telescopic sections of which are each provided with two opposite side portions and an intermediate rigid bottom.
• Fig. 1 shows schematically the evacuation arrangement in an active use position, illustrated in side view
• Fig. 2 shows the same as in Fig. 1, illustrated in perspective view
• Fig. 3 and 4 show schematically the evacuation arrangement in side view in respective swung in and swung out inactive positions.
