特徴とする油圧ショベル。In a hydraulic excavator, an upper rotating body rotatably mounted on a lower traveling body has a counterweight on one side and an arm on the other side via a boom, and detects a dump state and a cloud state of the arm. A state detection means and a cylinder device for moving the counterweight by the state detection means are provided, and the cylinder device moves the counterweight in a direction away from the central axis of rotation of the upper rotating body when the arm is in the dump state. A hydraulic excavator characterized in that the arm is connected to the counterweight so as to move the counterweight 1 in a direction approaching the rotation center axis when the arm is in a cloud state.
