Zusammenfassung:In a hydraulic excavator including a main controller that can execute area restriction control, the main controller is configured to calculate an operation velocity Vix of a front work device in a machine body coordinate system. The controller is further configured to calculate a movement velocity (dragging velocity) of a machine body in a gravity coordinate system and correct a direction of a calculated target velocity vector upward away from a construction target surface when generation of dragging is detected during execution of the area restriction control based on the calculated operation velocity of the front work device and the calculated movement velocity of the machine body.
