The travel gearbox, also known as the final drive, is an important component of an excavator. It is responsible for transmitting the power from the hydraulic motor to the track. It is the final stage in the power transmission system of the excavator and provides the necessary torque and speed to move the machine efficiently and effectively.
The travel gearbox is located in the undercarriage of the excavator and is responsible for driving the tracks of the machine. When hydraulic fluid is pumped to the motor, the motor rotates the pinion gear and transfers power to the ring gear through the reduction gear. This reduction gear decreases the speed and increases the torque output of the motor. The speed of the excavator is determined by the hydraulic flow, while the torque output is determined by the pressure of the hydraulic system.

The Final Drive Travel Gearbox is designed to meet the specific needs of SANY SY336 excavators. It has been engineered with the appropriate specifications for carrying capacity, torque output, and speed matching to ensure optimal performance. Our gearbox provides an excellent balance between power and efficiency, making it a great choice for your SANY SY336 excavator.
