The Final Drive Travel Gearbox, also referred to as the final drive or travel motor, is an essential component of an excavator. It is responsible for converting the power generated by the engine into torque, which is used to turn the tracks and propel the excavator forward. Without it, the excavator would be unable to move.

The Final Drive Travel Gearbox is installed in the undercarriage of the excavator, and it works by transmitting torque to a hydraulic motor, which in turn drives the tracks of the excavator. This process allows the excavator to move forward, backward, and turn. The gearbox is typically located towards the rear of the undercarriage, near the sprocket and the final drive motor.
Our Final Drive Travel Gearbox is specifically designed to fit the Caterpillar E120B OLD excavator, and it is engineered to match the excavator's key performance parameters, including load-bearing capacity, torque output, and speed matching. It is a direct replacement for the original Caterpillar E120B OLD gearbox, making installation straightforward and hassle-free.

| Parameter | Description |
|---|---|
| Excavator model | The specific make and model of the excavator for which the gearbox is intended. |
| Final drive ratio | The ratio of the number of teeth on the input gear to the number of teeth on the output gear of the final drive. |
| Shaft diameter | The diameter of the input and output shafts of the gearbox. |
| Torque output | The maximum torque output of the gearbox, measured in Newton-meters (Nm). |
| Speed matching | The range of speeds at which the gearbox can effectively match the speed of the engine to the speed of the tracks. |
Installing the Final Drive Travel Gearbox is a straightforward process that can be completed with basic tools and equipment.
