A swing gearbox, also known as a swing drive or swing motor, is a crucial component of an excavator's hydraulic system, responsible for rotating the upper structure of the machine. The gearbox consists of a set of gears, bearings, and seals enclosed in a housing and is powered by a hydraulic motor.

The swing gearbox is typically located near the excavator's cab and is attached to the upper structure. When hydraulic fluid is pumped into the motor, it turns the gears inside the gearbox, which rotates the upper structure of the excavator. The gearbox is designed to withstand high levels of stress and pressure and is built to last for years with proper maintenance.
Our swing gearbox is specifically designed to fit the Excavator Yuchai YC35-6 brand and model. Before purchasing, it is important to consider the following parameters:
| Parameter | Description |
|---|---|
| Size | Different excavator models require different sizes of swing gearboxes. Ensure that the size of the gearbox matches the size of the excavator. |
| Load capacity | The load capacity of the gearbox must match the weight and size of the excavator for proper operation. |
| Hydraulic flow rate | The hydraulic flow rate of the gearbox must match the hydraulic system of the excavator for efficient operation. |
When the swing gearbox starts to wear out, the excavator will exhibit certain signs, including:
Proper maintenance can extend the lifespan of the swing gearbox. Some important maintenance procedures include:
