Swing gearbox, also known as swing gear, is a vital component in excavators. Its primary function is to transfer power from the hydraulic motor to the excavator's slewing mechanism, which allows the excavator to turn.

The swing gearbox is installed in the upper part of the excavator, directly below the cabin. It is connected to the hydraulic motor and the slewing ring by a series of gears. When the hydraulic motor rotates, the gearbox turns the slewing ring, allowing the excavator to rotate.
The swing gearbox works by transferring power from the hydraulic motor to the slewing ring through a series of gears. As the hydraulic motor rotates, the gears in the gearbox rotate, which in turn rotates the slewing ring and allows the excavator to turn.
Our swing gearbox is specifically designed to fit the Excavator Caterpillar E313GC. Before purchasing, it is essential to ensure that the following parameters match:
| Parameter | Description |
|---|---|
| Dimensions | Size and weight of the gearbox |
| Power Rating | Maximum power output of the hydraulic motor |
| Speed Rating | Maximum speed of the hydraulic motor |
| Torque Rating | Maximum torque output of the hydraulic motor |
Over time, the swing gearbox may experience wear and tear. The following signs indicate that it is time to replace the swing gearbox:
Regular maintenance can extend the lifespan of your swing gearbox. The following maintenance tasks should be performed regularly:
