PROBLEM TO BE SOLVED: To provide a hydraulic feeding system that separately measures charged pressures of gas in accumulators of a plurality of systems. SOLUTION: The hydraulic feeding system, provided with the plurality of accumulators 1 storing pressurized working oil fed from a hydraulic source 9, comprises a plurality of hydraulic sensors 6 for detecting the oil pressure in each accumulator, a monitor (display means) 7 displaying oil pressure changes in oil pressure drop characteristic of each accumulator 1 calculated on the basis of the detection signal of each oil pressure sensor 6 in the process of extracting the working oil from each accumulator 1, and a controller (measuring means) 5 calculating the pressure at a changing point in the oil pressure drop rate as a charged pressure of gas in each accumulator 1.
