Provided is a slewing-type working machine including: a slewing motor; a capacity control device; a slewing control device operated by a slewing instruction operation to allow hydraulic fluid to be supplied from a hydraulic pump to the slewing motor; a slewing parking brake; a brake switching device; a brake release instruction unit which inputs a brake release instruction to the brake switching device so as to make the brake switching device switch the slewing parking brake to a brake releasing state after allowing hydraulic fluid to be supplied to the slewing motor; and a capacity limiting unit that limits the capacity of the slewing motor controlled by the capacity control device to a predetermined brake-release capacity value or less until a brake release point and allows the capacity to increase after the brake release point.
