The swing gearbox is installed at the base of the excavator's boom, which connects the upper structure of the excavator to the undercarriage. Its main function is to transfer power from the engine to the swing mechanism. It works based on the principle of the gear system, where the gearbox transmits rotational power and torque to the excavator's swing function.
