装置。 In an upper swing type construction machine having an upper swing structure and equipped with a swing parking brake mechanism that applies a brake to the rotation axis of the upper swing structure and releases the brake using hydraulic pressure, the above-mentioned brake The hydraulic pressure acting part of the mechanism is connected to the pilot pump via a solenoid valve that has a pressure oil communication oil passage position and a drain oil passage position. A grip sensor with a detection section that is sensitive to contact is provided, and the signal from the grip sensor is amplified via a controller, and its output can be applied to the solenoid valve, and the switching operation of the solenoid valve controls the pilot pump and brake. A brake device for parking a revolving body of construction machinery, characterized in that an intermediate oil path between a hydraulic pressure acting part of a mechanism and a hydraulic pressure acting part can be disconnected.
