WIPO Patent Application WO/2019/058622
Kind Code:
A1
Abstract:
According to the present invention, a hydraulic shovel 1 is provided with an informationized construction controller 60 that performs a machine control allowing a front work machine to operate on the basis of detection results of attitude sensors 63, 65, 67 and predetermined conditions, wherein the hydraulic shovel controller 60 has: a calibration attitude storage unit 60a that stores at least one predetermined calibration attitude of the front work machine in order to perform calibration of the attitude sensors; and a calibration attitude control unit 60b that performs a machine control so as to stop a hydraulic actuator when in a calibration attitude, detection target values of the attitude sensors and the detected values of the attitude sensors become the same. Thus, the time required for calibration can be reduced by improving the operability of adjusting the calibration attitude.
