An excavator is made up of a boom, dipper (or stick) and bucket. These pieces connect to a cab that sits on a rotating house. Most houses can rotate a full 360 degrees. Excavators are available with either tracks or wheels depending on the manufacturer and what the nature of a project is. Excavators are available in a variety of sizes 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 the excavator can be used for many different jobs.
Choosing the Right Excavator for The Job
The best way to find the right excavator for a project is to plan. Knowing exactly what kind of role the excavator will play on site will help determine what kind of excavator is needed. It is more efficient for a job to rent the right size equipment for what is needed instead of trying to make one piece fit for a variety of jobs.
What Are The Different Types of Excavators?
An excavator is often used for earthmoving projects. With a variety of options for sizes and attachments, an excavator can help to complete a job quicker and more efficiently when used to its full capacity. The variation in size allows them to be used in big construction projects and small backyard renovations. Wheeled excavators are popular in Europe and are used for working in urban areas since their wheels are kinder to finished roads and pavement than the traditional metal track.
The 7 Kinds of Excavators
There are seven key types of excavators available on the market: Crawler, Dragline, Suction, Skid Steer, Long Reach, Mini Excavator and Wheeled Excavator.
1. Crawler Excavators: The most commonly recognized excavator used for mining, trench digging and landscape grading the crawler excavator is what most people picture when they hear the word “excavator”. This kind of excavator is available on wheels instead of a track.
2. Dragline Excavators: A larger kind of excavator that uses a hoist rope and dragline system to clear earth for underwater projects, pile driving or road excavations.
3. Suction Excavators: Uses water jets and a high-pressure vacuum to clear dirt, soil, and debris. Operated out of a wheeled vehicle the suction excavator are used for underground applications, debris cleanup and other delicate excavation projects.
4. Skid Steer Excavators: A small machine with buckets that scoop away from the equipment cab that is great for residential projects and small clearing tasks. They’re also just known as a skid steer.
5. Long Reach Excavators: With arms that extend up to 100 feet with attachments the excavator is good for heavy-duty digging and industrial demo projects.
6. Mini Excavator: A compact, smaller version of a crawler excavator, mini excavators – often referred to as mini diggers – 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.
7. Wheeled Excavator: The wheeled excavator is the same as a regular excavator but is fitted on wheels instead of tracks. Growing in recognition for their use in city projects, wheeled excavators are becoming more and more popular.
