Frequent start-stop rotation in excavation work places enormous stress on the slewing transmission system. Once the swing reducer begins losing torque stability, operators may notice jerky rotation, delayed positioning, or metallic gear impact during turning. These issues become especially serious in quarry and foundation projects where excavators perform nonstop loading and directional movement throughout the day.
