Abstract:
This construction machine is provided with: an actuator (60) that uses, as a driving source, pressure oil which is pressure-fed from hydraulic pumps (61, 62); a solenoid valve (67) serving as an inhibition device that inhibits driving of the actuator (60) by cutting off the pressure oil pressure-fed to the actuator (60); an operation detection device (68) that detects whether the actuator (60) has been operated; a seating detection device (58) that detects seating on a driver's seat; and an integrated ECU (7) serving as a control device that performs control to automatically stop an engine (60), if a state where the operation detection device (68) detects that non-operation of the actuator (60) continues for a prescribed period, the seating detection device (58) detects seating on the driver's seat, and driving of the actuator (60) is inhibited by the solenoid valve (67).
