  • These excavators can use larger attachments to expedite the entire demolition process, from bringing down buildings to sorting and loading debris for disposal.
  • They are self-sufficient, often eliminating the need for additional machinery.


  • Transporting these larger machines is more complex, requiring a semi-truck with a lowboy trailer.
  • Navigating through certain routes can be challenging due to the truck’s turning radius.
  • They struggle with particularly demanding tasks like breaking large slabs or removing heavy building footers, which is where the 300-series comes in.

300-Series Excavators

The 300-series excavators are deployed when a project demands a comprehensive, turnkey approach.


  • These heavy-duty machines can tackle everything the 200 series can, and more.
  • Ideal for excavating building footers, breaking stubborn concrete slabs, and processing materials.
  • Their substantial lifting capacity, high horsepower, 54 cu yd bucket, and weight exceeding 60,000 lbs enable them to handle a wide range of tasks.


  • Their size, while an advantage for some projects, can be a drawback. They simply won’t fit on every job site.
  • The cost of renting a 300-series excavator is notably higher than that of a 200-series machine.

Each of these excavator classes has its strengths and weaknesses. It’s crucial to choose the machine that best suits your specific project requirements, as bigger isn’t always better.
