The invention relates to the field of engineering machinery, and discloses a safety early warning method for engineering machinery, a control device and the engineering machinery, and the safety early warning method comprises the steps: obtaining an actual value of first working condition data and an actual value of second working condition data of the engineering machinery; wherein the first working condition data comprises a first amplitude variation angle of the main arm, an extension distance of the main arm, a second amplitude variation angle of the fly boom and a load of the working platform, and the second working condition data comprises a linear distance between two axial ends of the main arm; determining a theoretical value of the second working condition data corresponding to the actual value of the first working condition data based on a pre-stored corresponding relationship between the first working condition data and the second working condition data; comparing the actual value of the second working condition data with the theoretical value of the second working condition data to obtain a comparison result; and sending early warning information according to a comparison result. According to the safety early warning method for the engineering machinery, the control device and the engineering machinery, the method is simple and easy to implement, and the engineering machinery can be effectively protected.
