摘要： The present application discloses a steering control system, a method and a crane. The steering control system includes: one or more first angle sensors, one or more second angle sensors, and a steering controller; each of the first angle sensors collects an actual steering angle of a wheel corresponding to a mechanical steering axle as a first steering angle; each of the second angle sensors an actual steering angle of a wheel corresponding to an electrically controlled steering axle as a second steering angle; the steering controller obtains a theoretical steering angle of the wheel corresponding to the electrically controlled steering axle in a corresponding travel mode according to the first steering angle, and compares the second steering angle with the theoretical steering angle, to control the wheel corresponding to the electrically controlled steering axle to steer according to a difference therebetween.
