Abstract:
A slewing-type work machine (100) is provided with: a slewing-state determination unit (73) that determines whether or not slewing of an upper slewing body (2) is in a deceleration state; and a capacity control unit (72) that controls a motor capacity. The capacity control unit (72) is configured to adjust the motor capacity to a capacity set for a composite operation during the composite operation in which an operation for slewing the upper slewing body (2) and an operation for operating an attachment (4) are simultaneously performed, while adjusting, when the slewing-state determination unit (73) determines that slewing of the upper slewing body (2) is in a deceleration state, the motor capacity to a preset default capacity even during the composite operation.
