The carrier rollers on an excavator are located under the top of the track. These rollers play a crucial role in supporting the weight of the upper structure and maintaining proper track tension. They ensure that the tracks remain in alignment and function smoothly as the excavator moves. Positioning the carrier rollers beneath the top side of the tracks allows them to guide the track assembly effectively, reducing wear and tear and enhancing the overall stability and maneuverability of the machine. Understanding the role and placement of these components is essential for maintenance and operation, as they directly contribute to the excavator's performance and safety.
