Professional Tips For Choosing An Excavator
There are two main types of excavators, one is the wheeled excavator and the other is the crawler excavator. Both configurations have their own advantages and disadvantages. You must first determine which configuration is best for your needs.
Then you need to determine whether you need a "standard" excavator or a specially configured excavator. There aren't many structural differences between different excavators, even when changing from one brand to another, an excavator is a multi-purpose machine, and it's usually just a matter of changing tools depending on the job that needs to be done.
However, some configurations apply to specific conditions, such as:
1. Demolition The boom of the excavator can reach the top of the building using a demolition tool, the cab is usually protected from falling material, and can be tilted upward so that the operator can see where he is working.
2. The zero tail swing excavator can be rotated without exceeding the surface of the machine, allowing it to work near walls without the risk of touching the wall.
3. Walking excavators are equipped with articulated "outriggers" that allow them to work on steep or rough terrain.
4. The multifunctional excavator has an arm with an additional joint to increase the movable range, thus increasing the versatility of the machine.
5. There are also road-rail models for working on railways, amphibious models for working on bodies of water, etc.
The main selection criteria for an excavator are its size and power. The size of the machine is characterized by its operating weight (for example, we can say: a 10 ton excavator). Available in a variety of sizes, from the smallest models of less than 1 ton to surface mining excavators of more than 100 tons.
You need to choose an excavator that suits your needs, a model that is too small may not be good enough for the job to be done, and a model that is too large may be unwieldy and expensive.
The weight of the excavator can give an idea of the overall size of the machine, but it is important to ensure that the arm can reach the maximum distance it has to work. Most manufacturers provide diagrams in their technical documentation that represent the arm's motion, showing the maximum height and depth that can be achieved.
Another important factor is the power of the engine, which powers the hydraulics that power the robotic arm and the tools mounted on it. The engine is related to the size of the machine, but can also vary, with a more powerful engine capable of performing a more difficult job.
Most excavators are equipped with diesel engines, although in recent years we have seen the emergence of some hybrid diesel/electric engines equipped with energy recovery systems.
Therefore, excavators must comply with the current anti-pollution standards of the country in which they are used, the most famous of which are the classification system in the United States and the emission standards in Europe.
Once you have determined the main characteristics of the desired excavator, you can also choose an excavator based on criteria such as ergonomics of the driving position, comfort, work aids or noise level.
