Excavators, also known as power shovels, are commonly used heavy equipment. There is no major construction project that doesn’t use excavators. This heavy machine is used for almost everything, from digging trenches to moving large boulders, which makes them basically practical for every construction projects.
What is an excavator?
An excavator is a heavy construction vehicle used to dig things or move objects. An excavator is essentially made of two parts: a driving base linked to a powerful boom arm that has an attachment made for excavating. The operator/driver sits inside a small cabin attached to the base and it’s in there that he controls the arm.
The excavator utilizes a hydraulic system to produce a hydraulic force so the mechanical arm can be controlled. A chain wheel system is also used in controlling the machines’ movement.
Excavators are used in both large and small-scale construction projects. In smaller projects, they are used to cut and fill, in road construction, used in marine structures in placing armours and huge rocks while in larger sites to excavate, move construction materials, getting rid of construction waste and other works. There are a number excavator types, which are classified based on its usage, brand and purpose.
An excavator isn’t limited to digging only. Though it’s common for this heavy machine to be used in creating trenches and site grading, they are also used in hauling construction materials, getting rid of brush, demolition, snow removal and mining.
What to look for on an excavator?
If you are looking to rent out an excavator, take note of their specifications. There a number of excavators available in the market, however, each type has varying weight, bucket sizes and power requirements. The mentioned 3 factors can help determine the amount of material that can be moved at a single time, and also the amount of time it will take to finish a particular project.
The cheapest option is the mini-excavators, however, they can’t move the same amount of material compared to large excavators. On the other hand, smaller excavators are ideal for small projects, especially in work areas where space is limited.
It is also important to take note of the different attachments that each machine has. For example, excavators have different make and model, you may be able to acquire extended boom arm or an arm that has multiple pivot points. Normally, these are common in mini-excavators. You can also find excavators that have numerous bucket attachments, like an attachment that can help in cutting, crushing and lifting.
