Abstract:
A hydraulic shovel (1) that comprises a controller (40) having a machine control unit (43) to execute machine control to cause a work machine (1A) to move according to a preset condition during operation of an operating device (45a, 45b, 46c) comprises an intervention strength input device (96) to be operated by an operator. The controller comprises a correction degree arithmetic logical unit (43m) that calculates, on the basis of the amount the intervention strength input device is manipulated, the degree of correction for an intervention strength that indicates the magnitude for the machine control to intervene in the movement of the work machine instructed by operation of the operation device. The machine control unit intervenes in the machine control of the movement of the work machine instructed by operation of the operating device by the corrected intervention strength based on the degree of correction calculated by the correction degree arithmetic logical unit.
