Swing Gearbox Fit for Excavator Daewoo DH220-5
The Swing Gearbox, also known as the swing drive or swing motor, is an essential component of an excavator's hydraulic system. It is responsible for controlling the rotation of the excavator's upper structure on its undercarriage. Here are some key features and uses of the Swing Gearbox:
- Controls the rotation of the excavator's upper structure
- Provides power to the hydraulic system
- Designed to handle heavy loads and withstand harsh conditions

Installation and Function
The Swing Gearbox is typically installed directly on the excavator's slewing bearing and is connected to the engine by a hydraulic pump. Once installed, it can control the excavator's upper structure to rotate 360 degrees, allowing the operator to efficiently dig and move soil. The swing gearbox works by converting the hydraulic pressure generated by the engine into mechanical energy to rotate the upper structure.
