5 Types of Excavators and Their Uses on the Construction Site

5 Types of Excavators and Their Uses on the Construction Site
  • Opening Intro -

    An excavator speeds up work by moving large amounts of soil and materials from the site.

    There are different excavators suitable for a wide range of applications.


Here are the top five types you should know.

Crawler Excavator for General Purpose-Construction

Also known as the standard excavator, it is the most recognizable machinery for general-purpose construction. It has two chain-wheel tracks and a cab that can rotate through an angle of 360 degrees.

Even though the tracks make it slower, a crawler is the best for maneuvering on hilly terrain. They exert low ground pressure, which gives the machine traction when working on soft soils.

Crawler excavators are used for landscape grading, digging trenches, and excavating the foundation. You can adjust the bucket and boom for different construction applications.

Wheeled Excavators for Asphalt and Concrete Surfaces

Wheeled excavators are similar to crawler excavators, but they have wheels instead of tracks. Wheels allow you to move the machine to an off-site location.

As such, wheeled excavators are ideal for public works and road building. The wheels are suitable for maneuvering on a hard and flat surface with concrete or asphalt.

Its principal disadvantage is that it gets stuck on mud or soft soils and is unsuitable for some applications. A lot of businesses use outriggers to keep the machinery stable during construction.

Backhoe Excavator for Moving Large Volumes of Materials

Backhoe excavators are often confused with general-purpose excavators. But it has a backhoe bucket at the front and an excavator boom at the rear.

The action of the backhoe attachment allows the machine to clear large volumes of materials. Backhoe excavators are suitable for soil grading, demolitions, and snow removal.

They can also move on flat roads, making them ideal for off-site construction jobs.

Skid Steers for Tight Spaces

Skid Steers are compact construction machines with the boom and bucket at the vehicle’s rare. The design allows skid steers to maneuver in tight spaces.

Their maneuverability makes them suitable for applications such as digging the pool or moving materials from the site. It allows for many different attachments like a snowblower, stump grinder, pallet forks, and angle broom.

Long-Reach Excavators for Hazardous Projects

As the name suggests, the excavator has an extended arm that can reach between 40 and 100 feet horizontally. They are ideal for applications where the machine cannot get too close to the site.

Therefore, long arm excavators are suitable for hazardous construction jobs. They are effective for demolition projects, but not in areas with tight spaces.

Conclusively, excavators are indispensable machines for many types of construction jobs. Consider leasing to manage the cost of acquiring an excavator for your project.
