Abstract:
Provided is a hydraulic shovel comprising a control controller that computes the magnitude of a positional difference in the height direction of a front work machine and a construction target face, such computation being on the basis of the position of the construction target face, the position of a vehicle main body computed by a GNSS receiver, and the attitude of the front work machine detected by an attitude sensor, wherein when the magnitude of the positional difference exceeds a prescribed value d1, the control controller: records, in a storage device, snapshot data of information relating to an operation sensor, a pressure sensor, an attitude sensor, the GNSS receiver, and a wireless device, in a prescribed period based on the foregoing prescribed value exceeding time; and on the basis of the snapshot data, diagnoses the cause of the magnitude of the positional difference exceeding the prescribed value.
