When we all thought, humans made them.
Excavators are large, heavy-duty, often mistakenly called power shovels; construction equipment. They consist of a boom, dipper, bucket and cab adhered to a rotating platform called house which sits on a carriage with wheels.
These diggers are widely used in digging trenches, holes, foundations, and in forest and construction work. Different types of excavators use varied working, but almost all of them are hydraulically operated.
