WORK MACHINE WITH PILOT CIRCUIT COMPRISING A PROPORTIONAL SOLENOID VALVE
To achieve both responsiveness of an actuator to an operation and front control functionality, a work machine including a front control section configured to calculate a limit command value for restricting an operation of a front work implement through control of, for example, a proportional solenoid valve 61b disposed in, for example, a pilot line 51b1 includes: for example, a bypass line 81B that bypasses, for example, the proportional solenoid valve 61b in, for example, the pilot line 51b1; for example, a bypass valve 81b disposed in, for example, the bypass line 81B; a switch configured to output a signal to turn on or off control by the front control section; an on/off determining part configured to determine whether the signal from the switch is an on signal that brings front control into an on state or an off signal that brings the front control into an off state; an open/close command part configured to generate an open command signal to open the bypass valve when the signal is determined to be the off signal and generate a close command signal to close the bypass valve when the signal is determined to be the on signal; and an output section configured to output the open command signal or the close command signal to the bypass valve.
