Excavators are used in the construction industry in a variety of purposes, mainly with the purpose of earth-moving and material handling. They are basically made from two parts, namely; an undercarriage for mobility that can either be wheels or tracks, and a powerful boom where a myriad of attachments can be fixed that gives it increased functionality.
When construction work begins, the very first machines seen on the field are excavators. Landscaping, earth-moving, or site clearing are some of the tasks that they will be doing. Hadn’t it been for this machine, many construction projects would be delayed for months or not finish at all.
Which is why most construction companies invest in excavator hire. Not only can they fast-track landscaping or earth-moving tasks, they also help in reducing manpower and operational cost. To get more insights, here are some primary jobs excavators are used for in the construction industry:
For large construction projects, activities such as digging large swathes of soil, backfilling and flattening an area, or prepare digging provisions for foundation work will always be needed. There are no other heavy machinery in the market that can easily do these tasks in the most efficient manner than excavators.
An excavator with a bucket attachment can dig and scoop large quantities of soil and rocks. With a projected productivity of 100 cubic meters per hour of digging, any digging operations may seem just a like snap. The bucket attachment has teeth-like edges that easily cut and scoop through soil.
In situations wherein the concrete strength design doesn’t meet design standards or a concrete element fails the concrete test, construction teams may resort to replacing it altogether. This will require a massive undertaking of demolition works, especially in concrete slabs.
With an excavator rental, this type of demolition job can be easily accomplished using an excavator with a breaker attachment. Breakers are similar to jackhammers, only larger in size. They can make quick work of concrete slabs, break footings, or topple columns.
Together with a bucket attachment, powerful boom, and a very mobile undercarriage, excavators are perfectly suited for hauling materials in long distances. Under one scoop, it can lift and carry 20,000 pounds of materials while moving.
In this setup, these excavators can easily transport large quantities of soil and debris onto trucks, making these machines the go-to choice for material disposal. Excavators are also used for transporting bulk materials such as sand, cement bags, steel, or any other construction items within the site premises
Before a construction project begins, soil boring will be conducted to evaluate the in-situ soil condition to obtain vital soil information such as soil bearing capacity, shear strength, and more.
An excavator with an auger attachment can bore through soil with ease. It can even accomplish multiple soil test sites in a day, making excavators the ideal machine to conduct soil boring tests. These augers have helical sections powered by hydraulic circuits that rotates quickly to easily drill through soil.
Picking up Oversized Material
An excavator fitted with a clamp attachment can pick up and haul large materials such as concrete debris, tree trunks, or large rocks that are too oversized for a bucket. This setup can also be used to crush debris and rocks into smaller pieces.
Large construction sites like residential developments will need basic provisions for roads. Though they are not necessarily concrete, the most common road provisions for construction are dirt roads enhanced with stabilizers.
However, these types of roads require a process called road ripping where the soil is loosened for decompaction to be sprayed with stabilizers. The ability of excavators with a rake attachment to do road ripping and be mobile at the same time makes them perfect for this type of job, especially if the dirt road is long.
