Abstract
To reduce reduction in operation speed of each of a plurality of hydraulic actuators.SOLUTION: A work machine according to an aspect of the present disclosure includes a lower travelling body, an upper slewing body slewably mounted on the lower travelling body, a first hydraulic actuator, a second hydraulic actuator, a first hydraulic pump configured to supply hydraulic oil to the first hydraulic actuator and the second hydraulic actuator, a second hydraulic pump configured to supply hydraulic oil to the first hydraulic actuator, and a control device configured to perform control for changing a flow rate distribution of hydraulic oil supplied to each of the first hydraulic actuator and the second hydraulic actuator in a case where a discharge flow rate of the first hydraulic pump reaches a predetermined flow rate when the first hydraulic actuator and the second hydraulic actuator are operated at the same time.SELECTED DRAWING: Figure 4
