Zusammenfassung:	The utility model provides a synchronous control system for platform lifting. The synchronous control system comprises a hydraulic source, a control valve, a speed regulating valve and an action cylinder, a plurality of action cylinders are in one-to-one correspondence with the speed regulating valves; the control valve comprises an electromagnetic reversing valve, a first one-way valve and a second one-way valve; an output port of the hydraulic source is connected with a first port of the electromagnetic reversing valve through a pipeline, and a backflow port of the hydraulic source is connected with a second port of the electromagnetic reversing valve through a pipeline. A third port of the electromagnetic reversing valve is connected with an inlet of the first one-way valve through a pipeline; a fourth port of the electromagnetic reversing valve is connected with an inlet of the second one-way valve through a pipeline; an outlet of the first one-way valve is connected with a first port of each speed regula
