A slewing-type working machine includes: an electric storage device capable of being charged with regenerative electric power for regenerating slewing energy of an upper slewing body while functioning as an electric power source for an electric slewing motor; an electric storage device and electric storage device controller detecting whether the electric storage device is under a normal condition with sufficient capacity to regenerate the slewing energy or under an abnormal condition without sufficient capacity; and a controller controlling a velocity of the electric slewing motor based on a result of detection by the electric storage device and electric storage device controller, wherein the controller performs a velocity limiting control for limiting a maximum velocity of the electric slewing motor when the electric storage device is under the abnormal condition.
