You will want to consider several factors like dig depth, lifting capacity, budget, worksite, counterweight, bucket capacity, and hydraulic attachments when deciding on the right excavator for your job. Excavators come in three general sizes: Mini or compact excavators weigh less than 6 metric tons (13,227 pounds) and fit well into small spaces, so they’re ideal for indoor projects. Midi excavators weigh between 6 tons (13,227 pounds) and 10 tons (20,000 pounds). Like mini excavators, they work well in small spaces, but can also tackle more standard construction work and provide additional power if you need it. Standard excavators can weigh from 10 tons (20,000 pounds) to 45 tons (90,000 pounds). They are commonly used for commercial construction and can handle multiple types of tool attachments.
