Abstract
A working control device comprises a hydraulic actuator such as the boom cylinder 36, the bucket cylinder 38, the operation device 160 that is operated by an operator to drive the hydraulic actuator, a hydraulic oil supply source consisting of the electric motor M1 and the hydraulic pump P1 that delivers hydraulic oil required to drive the hydraulic actuator; and a delivery oil amount control device (the controller for controlling rotation of the electric motor) that controls an amount of oil to be delivered from the hydraulic oil supply source in response to an operation of the operation device. The delivery oil amount control device is configured to perform a supplying oil amount control to deliver from the hydraulic oil supply source a required amount of oil for the hydraulic actuator to have a working speed corresponding to the operation of the operation device.
