A quick overview of the top 10 excavators in the world.
An excavator (also called an excavator) is a heavy-duty construction machine consisting of a boom, a bucket, a bucket, and a cab located on a rotating "house" on top of a landing gear with tracks or wheels.
The movement and functions of the excavator are achieved through the use of hydraulic oil, hydraulic cylinders and hydraulic motors-hence the name hydraulic excavator.
Excavators are usually used for major demolition, mining and other large projects.
Here are the ten largest excavators in the world:
