| Zusammenfassung: | A hydraulic excavator (1) is provided with a controller (40) including an actuator control section (81) which, when an operation device (45, 46) is operated, controls at least one of a plurality of hydraulic actuators (5, 6, 7) in accordance with the velocities of the plurality of hydraulic actuators (5, 6, 7) and a predetermined condition. The controller (40) determines, based on a sensed value from a posture sensor (50), the direction of a load exerted on an arm cylinder (6) due to the weight of an arm (9), outputs, upon determining that the direction of the load is opposite to a driving direction of the arm cylinder (6), a second velocity Vamt2 to the actuator control section (81), and outputs, upon determining that the direction of the load is the same as the driving direction of the arm cylinder (6), a third velocity Vamt3 to the actuator control section (81). |
