Hydraulic excavators are versatile machines used in various applications, from construction to mining. They consist of a boom, arm, and bucket, with the ability to switch out equipment. The upper structure contains the engine and hydraulic pump, while the underside has tracks for better maneuverability.
Hydraulic excavators, also called excavators, are used for a variety of applications. These high performance excavators are particularly useful for work areas that are more confined and less amenable to conventional equipment. Hydraulic excavators are used in applications ranging from road and pipeline construction to mining and excavating rocks containing diamonds and gold.
The working equipment part of a hydraulic excavator consists of hydraulic cylinders, a boom, an arm and a bucket. This work equipment is involved in the actual work of digging and loading. Adjusting the oil level in the hydraulic cylinder can change the accuracy of movement of the work equipment.
Those who have seen hydraulic excavators in action often compare the movements of the work equipment to those of a real boom. The arm portion of the equipment behaves much like the upper portion of a human arm, including the elbow and shoulder. The arm part behaves much like the part of an arm that starts at the elbow and ends at the wrist. The bucket portion can be compared to a cupped hand.
Hydraulic excavators offer a lot of versatility. The buckets on these excavators can be removed and replaced with drills, shears or even crushing equipment. It is this level of versatility that makes hydraulic excavators so useful in a wide variety of applications.
While the work equipment boom does the digging work, it is by no means the only important part of a hydraulic excavator. The upper structure of an excavator is also important and can be seen as the heart of the machine. Contains the engine, hydraulic pump and tank, and swing motors. These important devices are responsible for making the excavator dig and load.
The underside of a hydraulic excavator is also vital. It consists of the mechanisms that make the excavator move along the road, up a hill or across a construction site. There are hydraulic excavators which have wheels for movement and others which have tracks.
In the United States, most hydraulic excavators are equipped with tracks, as they are better suited to traveling on rough roads and maneuvering down steep inclines. Tracks are belt-like tracks used instead of wheels. Hydraulic tracked excavators are also more practical for muddy areas than wheeled ones.
