The invention discloses a dual-control type telescopic gangway ladder. The dual-control type telescopic gangway ladder comprises an upper platform, a suspension arm, a right winch, a stand column, a left winch, a steel wire rope, a lower ladder and an upper ladder, wherein the upper platform, the stand column and the suspension arm are mounted on a board deck on one side of a soft ladder; the left winch and the right winch are mounted on the bottom of the stand column respectively; the steel wire rope pulled by the left winch is directly connected with the bottom of the upper ladder after passing through the stand column, the suspension arm roller wheels on the bottom of the lower ladder to form a pulling structure for axially returning and concentrating the lower ladder relative to the upper ladder. 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.
