The invention discloses a boarding ladder system, a control method and engineering machinery. The boarding ladder system comprises a base, a turnover ladder, a lifting oil cylinder, a locking device, a plurality of sensors, an electronic pump, an escalator control valve group and a controller, the base is fixed on the side of a vehicle body; one end of the turnover ladder is hinged with the base; the two ends of the lifting oil cylinder are hinged to the base and the overturning ladder respectively. The locking device is installed on the upper portion of the vehicle body and used for locking the overturning ladder. The plurality of sensors are mounted on the base and used for detecting the position information of the turnover ladder, and are mounted in the locking device and used for detecting the position information of the locking guide rod; the electronic pump is used for providing hydraulic power; and the escalator control valve group is used for realizing direction switching and closing of a hydraulic loop of the lifting oil cylinder and the locking oil cylinder. According to the boarding ladder system, a person can conveniently control descending and ascending of the turnover ladder through the controller, when the turnover ladder is located at the lowest descending position, the person can conveniently get on a vehicle, when the turnover ladder is located at the highest ascending position, the locking device locks the turnover ladder, and the safety of the boarding ladder system is improved.
