Excavators are an essential piece of heavy equipment for most construction projects. Often referred to as diggers, excavators are used for all kinds of jobs like material handling, landscaping, demolition, mining projects, trenching, river dredging, and construction.

The Makeup Of An Excavator
The chassis of an excavator is made up of a boom, dipper, and bucket. These pieces connect to a cab that sits on a rotating house. Most excavator cabs can rotate a full 360 degrees for increased visibility. Excavators are available with either tracks or wheels depending on the manufacturer and the nature of the project.

Excavators are available in a variety of sizes and classes and can weigh up to 180,000 lbs. There are many other attachments for excavators that can take the place of the digging bucket to diversify the machine. By swapping out the bucket for an auger, drill, ripper, or rake, excavators can be used for many different jobs.

Choosing the Right Excavator for The Job

The best way to choose what excavator rental is needed for your project is to assess what exactly you need the machine to do. Identifying the right size of excavator, what attachments are needed, and how long you need the equipment will inform your decision to rent an excavator or buy one. It can be more efficient for a job to rent the right size of equipment for what is needed instead of trying to make one piece fit for a variety of jobs.

Excavators are often used for earthmoving projects or projects where lots of digging is required. That being said, the variety of attachments and excavator rental sizes available make these excavation machines useful in excavation projects of all sizes.

Typically, excavator sizes and classes are broken down into the following categories: mini, medium, large, demolition, long-reach, and wheeled. There are also specialty excavators made specifically for mining. Which size of digger you choose to buy or rent is often determined by the excavator's operating weight.

From a landscaping project to the construction of a completely new high-rise skyscraper, you can expect to see an excavator on almost any construction project, especially in the early stages. The variation in size allows them to be used in big construction projects and small backyard renovations. In addition to the different sizes of excavators, there are also several different types of excavators.

What Are The Different Types of Excavators?

The Cable vs. Hydraulic Excavator
The difference between the cable and hydraulic excavator comes from how the parts of the machine move. Cable excavators use a series of steel wires and cables to move the main parts and replaced steam shovels in the early 1900s.

Hydraulic excavators work by allowing the operator to use levers to control the movement of the hydraulic system to push and move the cylinders that control the boom and bucket of an excavator.

The 6 Kinds of Excavators

There are seven key types of excavators available on the market: Crawler Excavators, Dragline Excavators, Suction Excavators, Long-Reach Excavators, Mini Excavators, and Wheeled Excavators.

1. Crawler Excavators:

The most commonly recognized excavator used for mining, trench digging, and landscape grading is the crawler excavator. Crawler excavators get their name because of the way they travel on a job site with their tracks. They are incredibly powerful machines with hydraulic power. Because of the tracks, they are better suited for rough and uneven terrain.

2. Dragline Excavators:

Dragline excavators are a larger kind of excavator that uses a hoist rope and dragline system to clear dirt and soil for underwater projects, pile driving, or road excavations. Because of their weight and awkward shape, they're normally hauled in separate pieces to a job site before being assembled. These excavators are used for larger job sites and projects.

3. Suction Excavators:

Suction excavators use water jets and a high-pressure vacuum to clear dirt, soil, and debris. Operated out of a wheeled vehicle, the suction excavator is used for underground applications, debris cleanup, and other delicate excavation projects.

4. Long-Reach Excavators:

With arms that extend up to 100 feet with attachments, the excavator is good for heavy-duty digging, industrial demo projects, and reaching further than most other excavators.

5. Mini Excavator:

A compact, smaller version of a crawler excavator, mini excavators are useful in narrow job sites, job sites with obstacles, and jobs with delicate terrain like landscaping. Mini excavators have zero tail-wing capability and are ideal for small jobs. Mini excavators are also popular for home and DIY landscape projects.

When picking between renting an excavator vs a mini excavator, the size of the project and load size are usually the most important factors.

6. Wheeled Excavator:

The wheeled excavator is the same as a regular excavator but is fitted on wheels instead of tracks. Wheeled excavators are more popular in Europe and are typically used for working in urban areas since their wheels are kinder to finished roads and pavement than the traditional metal track. However, wheeled excavators are becoming more popular for their use in city projects.

Popular Attachments for Excavators
There are many different mini excavator attachments out there. Renting a specialized attachment can make your machine function more efficiently and work smoother for specific jobs. While there are 10 more popular types of excavator attachments - both for mini excavators and standard machines - you can pretty much rent the attachment that works best for the job you're doing.

The traditional excavator is fitted with a bucket that digs toward the cab and machine. However, this type of digging arm can have a thumb attachment instead which makes it easier to lift and move materials. There are also several types of buckets that can be attached to an excavator.

A rock bucket and a V bucket are two bucket types that can be attached to an excavator. A rock bucket looks similar to a digging bucket but with longer sharper teeth and a narrow V-shaped edge for cutting. The reinforced structural parts of a rock bucket give it the ability to break through hard rock while still maintaining structural integrity. The V bucket simplifies the task of digging trenches and is useful for laying utility cables and pipes.

Excavators can also be fitted with an auger attachment for digging holes, hammers for breaking up hard concrete and rock, rippers, compactors, rakes, and many other different kinds of tools. All of these attachments help to make the excavator a true multipurpose equipment type.
