The invention provides a hydraulic lifting platform system capable of achieving synchronous oil cylinder lifting. The hydraulic lifting platform system capable of achieving synchronous oil cylinder lifting comprises a gear pump connected with an oil tank and lifting oil cylinders; the oil outlet end of the gear pump is connected with a main oil line check valve, the oil outlet end of the main oil way check valve is at least connected with a one-level flow distributing device, namely, a flow distributing and collecting valve, and two oil outlets of the flow distributing and collecting valve are each connected with one lifting oil cylinder; an oil return line connected with the oil tank is connected between the main oil line check valve and the flow distributing and collecting valve in a by-pass mode, and the oil return line is provided with a second magnetic exchange valve; an emergency pressure relieving loop connected with the oil tank is arranged between the lifting oil cylinders and the flow distributing and collecting valve, the emergency pressure relieving loop is provided with a hand-operated direction valve, and loop check valves are arranged between the lifting oil cylinders and the hand-operated direction valve. According to the hydraulic lifting platform system, synchronous lifting of the lifting oil cylinders is achieved, and the emergency pressure relieving loop is arranged so that descending of the lifting oil cylinders can be achieved in an emergency situation.
