The swing gearbox is installed in the excavator's upper structure, connected to the machine's hydraulic system. It receives hydraulic fluid from the engine's pump and converts it into rotational energy, which is used to turn the upper structure. Here is an image of the swing gearbox in place:

When the operator activates the swing function, the hydraulic fluid flows into the gearbox's motor, which then turns the gearbox's output shaft. This shaft is connected to the excavator's upper structure, causing it to rotate.
