| description | The embodiment of the invention provides a control method and device for a lifting mechanism, a processor and a readable storage medium, and belongs to the technical field of engineering equipment. The method comprises the steps that the system pressure value of a hydraulic system and the first dip angle value of a shear fork connecting rod are obtained, and the system pressure value comprises the inlet pressure value of a telescopic oil cylinder and the front end pressure value of an electromagnetic proportional valve; determining a target pressure value based on the first dip angle value and a preset lifting speed; determining an oil cylinder flow value of a telescopic oil cylinder based on the target pressure value and a system pressure value; determining a target rotating speed of the driving motor based on the oil cylinder flow value; and controlling the driving motor to operate at the target rotating speed until the system operates stably. The target rotating speed of the driving motor is further determ |
