In excavators, a swing pedal is a foot-operated control that is used to rotate the upper structure of the machine, which includes the cab and the boom, around a vertical axis. By pressing on the swing pedal with their foot, the operator can smoothly and precisely control the rotation of the upper structure, allowing them to position the excavator and its attachments with greater accuracy and efficiency. The swing pedal is typically located on the floor of the cab, to the right of the operator's seat, and is one of several foot pedals used to control the excavator's movement and functions.
