Excavator Sizes
Size is chosen by depth, reach, bucket volume and how much room the site has:
- Mini excavator (under 6 t) — narrow plots, utility trenches, landscaping and indoor demolition.
- Midi excavator (6–15 t) — house foundations, drainage, septic tanks and medium trenching.
- Crawler excavator (20–30 t) — basements, bulk excavation, quarry loading and road cuttings.
- Large crawler excavator (over 30 t) — mass earthworks, mining and heavy rock work.
- Wheeled excavator — urban roadworks where the machine must move between work points on tarmac.
