Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the “house”.[1] The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements.[2] They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.[3] Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.

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
excavator toys
