Undercarriage Types
The track system that provides mobility and ground contact.
Rubber track
Continuous rubber belt tracks. Lighter weight, lower ground pressure, and won't damage paved surfaces. Standard on mini excavators. May wear faster in rocky conditions.
Steel track
Traditional linked steel track shoes. More durable in harsh conditions, better traction on slopes, and longer service life. Heavier and can damage finished surfaces.
Expandable/Retractable
Track width can be adjusted (typically hydraulically) to fit through narrow openings or widen for stability. Common feature on versatile mini excavators.
