The rotary gearbox plays a crucial role in the excavator. It is responsible for realizing the slewing movement of the upper structure of the excavator, such as the working device and the cab, enabling the excavator to flexibly change the working direction. In actual operations, the excavator needs to slew frequently for operations such as material loading and unloading and excavating soil in different positions. The rotary gearbox can accurately control the slewing speed and torque, ensuring that the excavator can work stably and efficiently under various working conditions. For example, when the Sany Transmission GS27D25 slewing reducer is applied to large-tonnage mining excavators such as Sany SY485 and SY550, it significantly improves the slewing ability and driving force of these models, and strengthens the stability of working on slopes and the operation ability in the face of complex working conditions.
