Excavators are useful machines for construction sites and projects. These versatile pieces of heavy equipment enhance job efficiency and ease. Knowing what kind of excavator is best for the job and choosing the right excavator size is vital for heavy machinery operators. But, the process of selecting the right equipment for a digging project can be a time-consuming and crucial task.
Continue reading to learn about different factors to consider when choosing an excavator for a job.
Identify Site Needs
While choosing the best excavator for the job, evaluate the job site and the project requirements. Are there tight or open areas? Do pipes and other utilities provide any risks or obstacles underground?
The location’s terrain influences the choice of excavator. Is the terrain area hilly or flat? Is the ground hard or soft? Do you need to be careful about damaging the landscape?
Additionally, recognize the project’s requirements. What is the excavator’s purpose? To what depth must it dig? How far does it need to reach? What is the maximum lift height? How much load must it support?
The answers to these questions can aid in determining the most suitable excavator for the specific job.
Consider the Attachments Required
The excavator is typically used for a specialized task rather than for multiple assignments. So, it’s helpful to note that attachments can change an excavator’s capabilities and performance. For example, an Auger driver attachment allows an excavator to effectively ‘drill holes’ in the ground, while a hydraulic breaker or ‘hammer’ can be used to break rock.
Even while an excavator seems like the best paper option, it may not be perfect for a certain task. All excavators are sturdy and reliable pieces of equipment. But if an attachment will alter its performance, it’s crucial to confirm whether a more powerful or additional element is needed for the job to be completed correctly.
Consider the Size of the Excavator
Excavators are versatile tools that can be compact for tight spaces or large for large construction projects. Selecting the right excavator size can improve work management and productivity. Mini excavators are ideal for light projects and smaller locations, like landscaping. Portability and adaptability are more crucial than load capacity. Larger excavators increase load capacity, resulting in higher time efficiency.
Consider Transportation Aspects
The weight and size of an excavator are equally crucial when not in operation. They affect the way you transport the machine to and from work locations. When selecting a machine size, consider how you intend to pull your excavator and double-check the weight constraints of any vehicles you wish to utilize.
Large excavators need specialized transportation equipment due to their size compared to compact excavators. If you are accustomed to hauling your compact excavator with a three-fourths-ton pickup truck, you must change your perspective when considering an excavator in the 10-ton plus size range. The size and weight of these machines often necessitate a larger truck-and-trailer combination than a compact excavator.
Consider Lifting Capacity Before Excavator Hire
The lifting capacity of an excavator is determined by its weight, lift point position, centre of gravity, and hydraulic capability. The excavator’s hydraulic capacity and tipping stability also limit the lifting capacity. Regarding excavator size classes, larger excavators can move heavier and bigger items.
A general rule of thumb is that hydraulics are used for the heaviest lifts in standard and large excavators. Therefore, such excavators are appropriate for heavy-duty processes. Thus, before an excavator hire, it’s crucial to consider its lifting capacity.
