Model overview
The Caterpillar 320 designation is associated with a mid-size crawler excavator family used for general excavation, utilities, site development and loading. Configuration and published specifications vary by generation, model year, boom, stick, undercarriage and regional package.
What to inspect when buying used
- Verify the exact model suffix and serial-specific configuration
- Measure undercarriage wear across links, bushings, rollers, idlers and sprockets
- Check boom, stick, bucket linkage and auxiliary circuits under load
- Review emissions-system and grade-control service history when equipped
Comparable machine families
- Komatsu PC210LC
- John Deere 210-class excavators
- Volvo EC220-class excavators
Hours, condition and ownership
Hours alone do not determine condition. Duty cycle, idle time, service history, undercarriage or tire life, hydraulic wear, structural repairs, emissions systems and installed electronics should be evaluated together.
Attachments and transport
Confirm coupler or pin geometry, attachment weight and hydraulic requirements. Record transport dimensions and weight in the actual travel configuration, including any bucket, blade, counterweight or separate work tools.
