Excavators, are used for digging, moving earth or other material, scrap and log handling, demolition, and more. Excavators range from mini-excavators with operating weights of less than 1 tonne to massive mining and quarrying models of more than 1,000 tonnes. While the majority of excavators are tracked crawlers, you can also buy wheeled excavators, which can be driven on the road and can move quickly around the jobsite.
