Excavator is a machine that is used to dig out soil mainly for construction purposes. These machines have a vast application in heavy construction activities wherein the soil is excavated and pulled back to the machine using hydraulic force. The effectivity of the excavator is examined by the time taken by the machine to load the fitted bucket from the source, brought back to the machine, and again dug in. Excavators are available in varied sizes depending on the bucket size, arm length, boom length, and operational speed. Different types of excavators include wheeled, crawler, suction, dragline, and others.
