Excavators are used in many ways:
Digging of trenches, holes, foundations
Material handling
Brush cutting with hydraulic attachments
Forestry work
Forestry mulching
Demolition
General grading/landscaping
Mining, especially, but not only open-pit mining
River dredging
Driving piles, in conjunction with a pile driver
Drilling shafts for footings and rock blasting, by use of an auger or
Hydraulic drill attachment
Hydraulic excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic-powered attachments such as a breaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation. Many excavators feature a quick coupler for simplified attachment mounting, increasing the machine's utilization on the jobsite. Excavators are usually employed together with loaders and bulldozers. Most wheeled, compact and some medium-sized (11 to 18-tonne) excavators have a backfill (or dozer) blade. This is a horizontal bulldozer-like blade attached to the undercarriage and is used for levelling and pushing removed material back into a hole.
