For various uses and purposes, different types of heavy machinery are used. They are most often used to perform tasks required for a building project to be completed. An excavator is a special category of heavy equipment (construction machines, earth movers, engineering vehicles, or just plain equipment).

An excavator consists primarily of a boom, bucket and cab on a revolving platform called a house that sits with tracks or wheels on top of an undercarriage. The number of explanations for the exit of the excavator’s functions and application. In the digging of trenches, holes and foundations, excavators may be used. It may also be used with hydraulic attachments in handling materials and in brush cutting. The use of excavators also promotes and facilitates forestry work. An excavator is used in construction, in particular for large infrastructures, to assist in demolition, general grading, landscaping, and lifting and placing heavy items such as pipes. Excavators also assist in mining, river dredging and pile pushing.
A hydraulic compact excavator or mini excavator has tracks or wheels and weighs between 0.7 and 7.5 tonnes. The world’s largest manufacturer of construction equipment, Caterpillar, has a compact or mini excavator that weights just 1,610 kilogrammes or 3,549 pounds and has a 19 hp performance. The mini excavator consists of a regular backfill blade with an autonomous boom swing. It differs from other heavy equipment in such a way that all the movements and functions of this machine, particularly its working group and blade, are responsible for the transfer of hydraulic fluid into hydraulic cylinders. The hydraulic fluid-powered motors also enable the rotation and travel functions of the lightweight excavators.
Smaller or larger styles can come with the Dragline Excavator. In civil engineering, smaller types are used for road and port building. While the larger types are used to transfer overburden above coal and for tar-sand mining in strip-mining. Draglines usually weigh about 2000 metric tonnes, but larger draglines weighing 13,000 metric tonnes are also available. The dragline bucket system has a large bucket suspended from a large truss-like structure called a boom with wire ropes. This bucket is manoeuvred by ropes and chains and held by a rope hoist (whose power comes from large diesel or electric motors). The dragrope is responsible for a horizontal fashion for carrying and drawing the bucket assembly. In making the ropes for the dragline to perform different operations, a professional operator may apply his abilities.
