Excavator

An excavator is a piece of heavy construction equipment used for many functions from digging to material handling to demolition to mining and general landscaping.  They range in size from small, compact mini excavators weighing in at 2000 pounds to gigantic powerful machines weighing in excess of 2 million pounds.   Excavators are often referred to as diggers, power shovels, 360's and trackhoes.

Most excavators consist of a cab, boom, stick, bucket, tracks, and a rotating platform that contains the engine and hydraulics.  These machines run on a system of hydraulic cylinders and motors actuated by the fluid pressure from hydraulic pumps.  These pumps are usually driven by diesel engines ranging in size and power relative to the machine.

A medium sized excavator run by an experienced operator can move massive amounts of material in a short period of time.  Many excavators are also equipped with auxiliary hydraulic systems allowing them to power additional features such as jackhammer, auger, flex buckets, thumbs, grapples, and other attachments.
