Excavator is a machine used by the civil engineer. The main function of the excavator is to dig the earth during the foundation of the building. It is comprised of a boom stick, which is nothing but a joined arm, a cab, which is located on the spin of the undercarriage along with the wheels and a bucket. It is designed in such a way that it looks like a natural sequence of the scoop.

In the present days the work of excavator has exceeded beyond imagination. Nowadays the range of its work has expanded to a great extent. With the launch of hydraulic excavator, the works of the engineers have become quite easy. Hydraulic excavator comprises of grapple, breaker and auger, which have proved its versatility in the engineering work apart from excavating. There are many excavators which features quick attach system of mounting. This system allows a simplified way of attaching and is in great demand in the jobsite. Excavator works together with a bulldozer and a loader. Most of the compact excavators have consists of a backfill blade. This blade resembles a bulldozer and is linked to the undercarriage. Their main function is to push and remove the earth in the hole.
