The invention discloses a control method and device of engineering machinery, the engineering machinery and a readable storage medium, the engineering machinery comprises a damping control valve set arranged on a feedback oil way from a main valve to an oil pump, the damping control valve set is used for outputting damping, and the method comprises the steps that the length of a suspension arm, the angle of the suspension arm and the rotating speed of an engine are obtained; and under the condition that the suspension arm length, the suspension arm angle and the engine rotating speed meet preset conditions, control strategies of the oil pump and the damping control valve set are determined. According to the application, the damping control valve group is arranged, and different control strategies can be realized for the current of the oil pump and the output damping of the damping control valve group by acquiring the length of the suspension arm, the angle of the suspension arm and the rotating speed of the engine under the condition that the three parameters meet the preset conditions, namely the corresponding working conditions, so that the safe operation of the engineering machinery is ensured.
