The Final Drive Travel Gearbox, also known as the final drive, is a crucial component in the powertrain system of an excavator. It provides the necessary torque and speed to drive the excavator tracks, allowing it to move forward and backward with ease.

The travel gearbox is installed in the undercarriage of the excavator and is responsible for transferring power from the hydraulic motors to the tracks. The gearbox works by using a series of gears that reduce the high-speed rotation of the hydraulic motor to the slower speed needed to move the tracks.
The Sumitomo SH120 Travel Gearbox is designed to handle heavy loads and can withstand the harsh conditions of mining and construction sites.
The gearbox provides high torque output, allowing excavators to climb steep inclines and navigate difficult terrain with ease.
The gearbox is designed to match the speed of the hydraulic motor to the tracks, providing smooth and precise movement.
The gearbox is made with high-quality materials and is designed to withstand the wear and tear of heavy use.
The gearbox is designed for easy maintenance, with accessible components and simple disassembly and reassembly procedures.
The Sumitomo SH120 Travel Gearbox is designed specifically for use with the Sumitomo SH120 excavator. It is engineered to provide optimal performance in terms of load-bearing capacity, torque output, and speed matching.
