As an essential component of a hydraulic excavator, the travel gearbox, also known as the final drive, is responsible for transmitting the power from the hydraulic motor to the track, driving the excavator to move forward or backward. The travel gearbox is a critical part of excavator that ensures smooth and efficient movement. Our product, the Final Drive Travel Gearbox Fit for Excavator SANY SY55-9, is designed specifically for SANY SY55-9 excavators, with superior performance and unparalleled quality.

The travel gearbox is mounted to the excavator's undercarriage and is usually located between the hydraulic motors and the track sprockets. It works by transmitting the torque generated by the hydraulic motor to the track, which drives the excavator forward or backward. The travel gearbox converts the high-speed, low-torque input from the hydraulic motor into low-speed, high-torque output to drive the track, providing the necessary power for the excavator to move smoothly and efficiently.
Our gearbox is made of high-strength alloy steel, ensuring durability and longevity even under extreme conditions.
Our gearbox is designed with advanced technology, ensuring efficient power transmission and low noise and vibration levels.
Our gearbox is manufactured to strict tolerances, ensuring high precision and reliability in operation.
Our gearbox is designed for easy installation and maintenance, reducing downtime and increasing productivity.
Our gearbox offers excellent value for money, providing a cost-effective solution to your excavator's power transmission needs.
Our travel gearbox is specifically designed for SANY SY55-9 excavators, ensuring optimal performance and compatibility with your machine's key performance parameters, including load capacity, torque output, and speed matching.

Excessive noise or vibration during operation.
Sluggish or uneven movement of the excavator.
Leaking oil or other fluids from the gearbox.
Excessive wear or damage to the gearbox components.
Loss of power or performance from the excavator.
Regularly check and change the gearbox oil to ensure proper lubrication.
Perform routine maintenance checks to identify and address any issues early on.
Avoid overloading the excavator, which can cause excessive wear and tear on the gearbox.
Operate the excavator at appropriate speeds and avoid sudden acceleration or deceleration.
Keep the undercarriage clean and free of debris to prevent damage to the gearbox components.
Our travel gearbox is designed to be easy to install, with clear instructions provided. Make sure to follow these steps carefully to ensure proper installation:
Remove the old gearbox from the excavator.
Clean the mounting surfaces and ensure that there is no debris or dirt.
Install the new gearbox onto the mounting surface and align it with the hydraulic motor and track sprockets.
Tighten the bolts to the manufacturer's specifications.
Fill the gearbox with the recommended oil and check for leaks.
