Our Final Drive Travel Gearbox is an essential component for your excavator. It is responsible for transmitting the power from the hydraulic motor to the track, allowing your excavator to move and operate. Our product is specifically designed to fit the Hitachi ZX450-3 excavator, ensuring optimal performance and efficiency.
A travel gearbox, also known as a final drive, is a mechanical component that transmits power from the hydraulic motor to the track of the excavator. It is responsible for controlling the speed and direction of the excavator, allowing it to move and operate effectively.

The travel gearbox is installed at the end of the hydraulic motor and before the final drive sprocket. It works by transmitting the power from the hydraulic motor to the final drive sprocket, which drives the track and moves the excavator. The gearbox also reduces the speed of the hydraulic motor and increases the torque to provide better traction and stability.
Our travel gearbox is specifically designed to meet the requirements of the Hitachi ZX450-3 excavator. It has been designed to deliver optimal performance in terms of load capacity, torque output, and speed matching. The product is rigorously tested to ensure it meets the highest standards of quality and durability.
