When a large excavator begins to show delayed swing response, abnormal gearbox noise, or unstable upper structure rotation, it usually indicates internal gear wear or torque loss in the slewing system. In heavy mining or quarry operations, this condition quickly escalates into reduced loading efficiency and unexpected downtime, especially under continuous 10–12 hour workloads where swing systems are constantly under stress.
