The steel wire rope pulled by the right winch is connected to the bottom of the upper ladder after passing through the stand column and a cooperated roller wheel system to form a dual-direction rotary structure on which the upper ladder is linked with the lower ladder to take the upper platform as a hinged point. The pulling structure and the dual-direction rotary structure are provided with winches which are independently operated, are randomly regulated with a permitted range, and in efficient butt joint, so that navigator detours the gangway ladder from the soft ladder as early as possible, the passing condition of the navigator is improved, and the navigator can timely go on board to provide service conveniently.
