Torque capacity: The gearbox must be able to handle the high torque generated by the engine and the hydraulic system. Make sure the gearbox has a sufficient torque rating to avoid premature failure.
Gear ratios: The gearbox should have a range of gear ratios that allow the excavator to operate efficiently in different conditions, such as high-speed hauling or low-speed digging.
Durability: The gearbox should be constructed with high-quality materials and designed to withstand the harsh operating conditions of an excavator, such as dirt, debris, and high temperatures.
Ease of maintenance: The gearbox should be easy to access and maintain to minimize downtime and repair costs.
