Final Drive Travel Gearbox Fit for Excavator Caterpillar E120B OLD
Final Drive Travel Gearbox Fit for Excavator Caterpillar E120B OLD
The Final Drive Travel Gearbox, also known as the final drive, is a crucial component of an excavator's hydraulic system. It is responsible for transmitting power from the hydraulic motor to the track and propelling the excavator forward and backward. Our product, designed specifically for Caterpillar E120B OLD excavators, boasts high efficiency, durability, and reliability.

Installation and Functionality
The travel gearbox is installed in the rear of the excavator, connecting the hydraulic motor to the final drive sprocket. It works by transmitting the torque generated by the motor to the track, resulting in movement of the machine. Our product is designed with precision to provide optimal performance in terms of torque output, speed matching, and load-bearing capacity.
Core Features and Advantages
- High transmission efficiency, reducing power loss and fuel consumption
- Robust and durable, with a long service life and low maintenance requirements
- Precise design and manufacturing, ensuring compatibility and ease of installation
- High load-bearing capacity, providing stability and safety in operation
- Low noise and vibration, ensuring operator comfort and reducing wear and tear on other components
Parameters to Consider When Purchasing
| Parameter | Description |
|---|---|
| Machine model | Ensure compatibility with the excavator model |
| Operating environment | Consider factors such as temperature, humidity, and terrain |
| Load capacity | Determine the maximum load the gearbox will need to handle |
| Speed requirements | Consider the required speed range and acceleration |
| Installation requirements | Consider any constraints on space and mounting options |
Signs that it's Time to Replace Your Travel Gearbox
