SLEWING CONTROL DEVICE FOR HYBRID CONSTRUCTION MACHINE AND HYBRID CONSTRUCTION MACHINE
A brake control unit (323) operates a mechanical brake (29) when a slewing operation amount detected by a slewing operation amount detection unit (31) indicates slewing stop and when a slewing speed detected by a slewing speed detection unit (27) is equal to or lower than a predetermined speed. A time measurement unit (322) measures a brake operation time period during which a brake operation detection value detected by a brake operation detection unit (30) exceeds a predetermined threshold. When the mechanical brake (29) is operated and when the brake operation time period measured by the time measurement unit (322) exceeds a predetermined reference time period, a slewing control unit (321) stops outputting a slewing command.
