Excavators are of different types, and each type has unique power requirements and attachments that do not have one size that fits all applications. There is a wide range of machine types, but most of them operate on a similar principle. They use diesel to run hydraulic pumps that help to drive the escalators.
Escalators have three main parts that are combined to enhance the practical function of the machine. They include the following;
The drive system
It comprises the excavator undercarriage that enables the machine to move in different directions and maintain stability. The drive system has a gear system and bearing that connects the engine to the drive system. It is mobile and allows the excavator to turn around.
The track is another part of the excavator that turns together with toothed gears to enhance alignment. Tracks may be composed of hard steel that is ideal for the rough areas in which excavators operate.
The excavator’s arm works as a series of hinges that enable the escalator to move up, down, close and open, move forward and backward. The excavator’s arm is made up of a stick, a boom, and a bucket. A hydraulic cylinder controls the boom under pressure. The stick enables the arm to move the hinge around as a multi-functional unit. The bucket aids in cleaning up after work is done, and it can take various shapes.
The excavator house
The excavator house joins the cab and engine to the undercarriage. It is the control center that converts fuel into the energy used in the operation of the machine. It is made up of engine pumps, main control valves, and other controls that work together for the proper functioning of the excavator.
Types of Excavators
Different types of excavators exist, and their use depends on the kind of project to be carried out. Smaller machines are used for drilling and digging, while larger excavators are used for big tasks, and they have tools to allow them to work effectively. The common types are;
Long reach excavators
They have a more extended boom and arm that makes them efficient for working in areas that are difficult to reach. Long-reaching excavators are ideal for demolition projects and bringing down structures that are above a water body. Operators can fix other excavator attachments to the arm to perform additional tasks such as cutting and crushing.
These are machines that are used in heavy-duty construction jobs and mining. And they are run by two continuous tracks. Crawler excavators use hydraulic power to lift heavy materials and soil. The constant chain enables them to go up and downhill with less risk and is suitable for rough landscaping terrain. Crawlers move at a slow pace, but they are very flexible and stable.
These are excavators that are used in road construction projects and underwater applications. It has a hoist rope, bucket, and coupler that help remove water from the construction site. The tools and equipment used by dragline excavators are heavy, and therefore, they are assembled on the site.
The choice of excavator for your project depends on the working conditions, such as the type of soil, space, size, and machine speed.
