Different types of machines are used for different applications and purposes. They are most often used when performing the tasks required to complete a construction project. A special type of heavy equipment (construction machinery, earth moving machinery, construction vehicles or simple equipment) is an excavator.

The excavator consists primarily of a boom, bucket and cab on a rotating platform called a housing, which is located on the track or undercarriage of the wheels. Number of output reasons for excavator functions and applications. You can purchase komatsu parts or aftermarket komatsu parts for the heavy machinery.

Excavators can be used to dig trenches, pits and foundations. It can also be used when handling materials and cutting brushes with hydraulic attachments. Forestry has also become easier thanks to the use of excavators. 

In construction, especially large infrastructure, excavators are used to assist with demolition, general classification, landscaping, and the lifting and placement of heavy objects such as pipes. Dredgers also help dig, dredge rivers, and kill pilots.

Compact hydraulic excavators or mini excavators have tracks or wheels and weigh from 0.7 to 7.5 tonnes. Caterpillar, the world's largest manufacturer of construction equipment, has compact or mini excavators that weigh only 1,610 kilograms and produce 19 hp. Mini excavators generally consist of standard backfill blades with independent boom rotation. 

Unlike other machines, the transmission of hydraulic fluid to the hydraulic cylinders is responsible for all the movements and functions of this machine, especially the working groups and guards. The turning and driving functions of the compact excavator are also activated by a fluid-powered hydraulic motor.
