Beschreibung
Zusammenfassung:	A hydraulic control system in a working machine, configured such that hydraulic energy of oil discharged from a hydraulic actuator is stored as pressure into an accumulator and such that the pressurized oil stored in the accumulator is converged into oil discharged from a hydraulic pump, wherein the pressurized oil in the accumulator is adapted to be efficiently used without waste. A control device (27) obtains the actuator supply flow rate (Qc) to be supplied to a hydraulic actuator based on the amount of operation of a hydraulic actuator operating device and on the discharge pressure (Pp) of a main pump (10) and controls the discharge flow rate (Qp) of the main pump (10) and an accumulator flow rate (Qa) so that the actuator supply flow rate (Qc) is the sum of the discharge flow rate (Qp) of the main pump (10) and the accumulator flow rate (Qa).
