Excavator
Excavator
A typical modern excavator: a CAT 325C, fitted with quick couplerand tilting bucket.
For the AMD CPU microarchitecture, see Excavator (microarchitecture).
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.

Terminology
Excavators are also called diggers, JCBs (a proprietary name, in an example of a generic trademark), mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to 360). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe.[5] In the UK, wheeled excavators are sometimes known as "rubber ducks."[6]
Usage[edit]
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
An old excavator under the Northwest (nowTerex) name at thePageant of Steamgrounds
Excavator demolishing a house. Note the hydraulic thumb
Link-Belt excavator trenching
