Swing Gearbox Fit for Excavator Daewoo DH370-7
Swing gearbox is an essential component of an excavator that helps in smooth rotation of the cab. It is responsible for the rotation of the upper structure of the excavator and allows it to swing right and left. Here are a few key functions and features of the Swing Gearbox:
- Allows excavator to perform 360-degree rotation
- Helps excavator to perform digging and trenching operations with ease
- Helps in reducing the load on other components of the excavator
- Offers smooth operation even in harsh working conditions

Swing Gearbox installation and working principle
The Swing Gearbox is installed at the base of the cab and connected to the excavator's engine through hydraulic systems. It is mounted on the slew ring and has a pinion that meshes with the ring gear to rotate the cab. Here is the working principle of the Swing Gearbox:
- When the operator uses the joystick to rotate the cab, it triggers the hydraulic system.
- The hydraulic oil flows into the Swing Gearbox and creates pressure, which in turn, rotates the pinion gear.
- The pinion gear meshes with the ring gear, and the cab starts to rotate.
