The undercarriage of an XCMG excavator is a vital element, providing essential support and stability to the machinery. It consists of various components, including tracks, rollers, idlers, sprockets, and links. Proper maintenance of these components is imperative to ensure the excavator operates smoothly and to minimize downtime caused by repairs.

Tracks: The tracks are the most significant part of the undercarriage, delivering traction and support to the excavator. Due to extended use, tracks may experience wear, making regular inspections for signs of deterioration essential.

Rollers: Rollers serve to support the tracks and maintain their position. Similar to tracks, they are subject to wear over time, necessitating routine inspections for any indications of damage.
