The present invention discloses a hydraulic energy saving control system for forklifts comprising a steering device (7) and an operating valve (6), a first variable displacement pump (1) having a load feedback signal receiving port connected to the load feedback signal output port of the steering device and the load feedback signal output port the operating valve is connected, wherein the oil discharge opening of the first variable displacement pump is connected to the oil input port of the steering device and the oil input port of the operating valve; a second variable displacement pump (2) whose oil discharge port is connected to the oil input port of the operation valve; and a control unit connected to the second variable displacement pump. The method for reducing the operating energy consumption for forklifts is that during operation of the steering device and / or the operating valve, the first variable pump takes care of the supply of the steering device and / or the operating valve of the forklift, wherein during high flow rate requirement of the operating valve of the forklift second variable displacement pump, together with the first variable displacement pump supplies the supply of the operating valve with oil.
