The invention relates to the field of engineering machines, and discloses a method and device for calibrating a position value of a trolley and an engineering machine. The method comprises the steps that a real-time position value, which is transmitted because a fixed position sensor is triggered, of the corresponding trolley in a rotating speed measurement module is received, wherein the fixed position sensor is mounted at a fixed position value position where the fixed position sensor can be triggered by the trolley; the real-time position value is compared with a fixed position value; and under the condition that an absolute value of a difference value between the real-time position value and the fixed position value is smaller than or equal to a preset value, the real-time position value is replaced with the fixed position value so as to calibrate the position value of the trolley. Therefore, the calibration of the position value of the trolley running on the engineering machine isrealized, a position of the trolley is timely and effectively monitored, the accuracy of the real-time position of the trolley is improved, and the error of a position signal of the trolley is reduced.
