What is considered a large excavator
What to consider when selecting a bucket
- Truck Size: Ideal to load a truck in 4-5 passes when using a large excavator
- Impact Condiions: How diffiicult it will be to get material out of ground
- Material Density: How much a bucket load would weigh, in ideal conditions, when 100% full.
- Durrability: General Duty to Extreme Duty
- Edge Configuration: Spade edge vs Straight edge
- Tooth Spacing
- Tooth Size
CAT's Durrability Catagories of Buckets
General Duty (General excavation and truck loading of dirt, loam and gravel
Heavy Duty (general construction applications in a wide range of materials with a small aggregate size)
Severe Duty (small to medium sized materials like sandstone, shot limestone, shot granite and the like.)
Extreme Duty (aggressive digging and loading applications in broken slag, limestone, broken granite, basalt, hematite and iron ore.)
Spade edge: Offers better penetration and faster cycle times in harder materials. Used when breaking ground is the primary requirement.
Straight edge: Configurations provide for better cleaning and finishing work. Used in soil work, site development and trenching.
Lower tooth count is used in hard-to-dig rock. It results in better penetration, just like the spade edge. Used in quary work.
Tighter tooth spacing used in soil work. Bridging between the teeth and higher tooth density results in a better floor and reduces the time spent finishing the trench.

Association of Equipment Manufacturers (AEM) lumps crawler excavators into three general size categories. What are they?
- Mini or Compact (0 – 6 metric tons; or <13,227 pounds)
- Midi (6 – 10 metric tons; or 13,227 – 22,046 pounds)
- Standard/Full-Size Crawler Excavators (10 – 90 metric tons; or 22,046 – 198,416 pounds):
Benefits of a Compact/Mini excavator
small excavators that get into the tight places
Certain Class 1 and Class 2 trucks can haul compact excavators without requiring the driver to have a Commercial Drivers License (CDL)
3-4 metric tons (6,613 – 8,818 pounds) are the most popular
Extremely versatile, performing in-building work, tight subdivision sewer repairs, water line installs and foundational repair that may not require the size of a conventional excavator
Benefits of a Midi/Mid-Size excavator
Provides digging and lifting capabilities more in line with their full-sized counterparts, but are still compact enough that they provide advantages in transportation and jobsite access.
Benefits of a Standard/Full Sized excavator
Widest spectrum of excavators available on the market today.
