Excavator Equipment
Excavators overview
Full sized excavators have been a mainstay of construction projects for years. The sheer power they can bring to bear for digging trenches, foundations, and other types of excavation is essential to getting a job done quickly and effectively.
Due to their enormous weight, the need for a rock-solid digging platform, and the treacherous ground conditions they often encounter, the vast majority of excavators use steel tracks for mobility. Wheeled excavators are available, but much less common. Steel tracks give excavators outstanding traction for working on slopes, mud, loose dirt, and other potentially hazardous surfaces.
As with the other machines we've talked about, excavators can also be fitted with multiple attachments, but there are fewer reasons to do so since it's such a specialized machine. One popular use, though, is demolition: an excavator fitted with a crusher or hydraulic thumb can tear through reinforced concrete and other support structures.
You may want to choose different types of buckets to dig with, depending on the application. For all-purpose use, general buckets offer the best combination of light weight and high capacity. Heavy-duty buckets feature stronger sidewalls and teeth, and rock-ripping buckets can tear through the hardest surfaces.
