Exavator comes in various sizes and can have different functions. The most common use is to dig ponds, ditches, dig holes and kill vegetation.

Types of excavator
By using a front loader, general-purpose excavators can pick up large tools such as buckets and trenchers. They use tracks for forward movement and have a wide range of attachments that make them very versatile. These machines are usually built on skids or semi-pneumatic tyres, meaning they can be used off-road without damaging the site or causing road damage.
The wheeled excavator is a general-purpose excavator. The main difference is that instead of running on tracks, they run on wheels. It can be transported easily to the job site in a relatively short time and save cost.
3.Short swing radius excavators
The short-radius excavator is a compact version of a general-purpose excavator with excellent maneuverability at construction sites and other environments where tight space requirements are critical. The shortened swing radius offers significant improvements in efficiency, cost savings and operating safety for challenging tasks like tight excavation work, underground utility cuts, street reconstruction, bridge construction and other civil engineering projects.
Long reach excavators are the last general-purpose excavators in our series. These machines have an extended boom and arm which give a longer working range for tasks quite away from the machine that is hard to reach such as underwater digging, deep trenching, and the location of utility pipes at such a depth as to resist freezing temperatures. They can also be used for snow removal and landscaping.
A backhoe loader is a machine commonly used in construction, mining, and landscaping. It is usually used for earthmoving operations and consists of a large bucket or blade attached to the front of the machine, which is followed by an arm. The bucket or blade of the backhoe loader are designed to push the surface of materials such as soil. The boom and arm at the back have similar functions as those of general-purpose excavators, but they rotate only about 205 degrees.
Type of excavator attachment tool
Attachment tools are used with excavators to maximize work performance and utilization depending on the type of task that needs to be performed. Before we identify the different excavator sizes, we must know the different attachment tools first.
The most common bucket for excavators is a wide J bucket, but some machines also use V, T or curved buckets. The scooping action refers to how the bucket scoops up dirt and rocks.Other types of buckets include: square-hole and square-face buckets; rectangular and diamond buckets; smooth, rough and ribbed drums; and hydraulic attachments such as the backhoe attachment on a skid steer loader.
This attachment increases the capacity of an excavator bucket. Thumbs help secure and strengthen the grip while excavating larger objects. As well as being great for general construction, it can also be used to pick up timber, stone, concrete and aggregates.
This attachment is used to dig holes quickly and more conveniently. These augers are supported by hydraulic spiral blades that allow the excavator to dig holes quickly and efficiently. They are ideal for landscaping and construction professionals.
Hydraulic breaker attachments are used to break or demolish structures, pavements, or other solid surfaces. Hydraulic hammers can be used to make the demolition quicker. A broken asphalt allows water to penetrate and crack the pavement, making it more vulnerable to cracks.
Shears are the ideal tool for demolishing buildings and steel structures, as well as for scrap and recycling applications, such as cutting metal beams, sheets, and wires. The combination of a powerful hydrostatic chassis, high-performance engine and a robust design makes this excavator truly unique.
6.Hydraulic quick coupler
Hydraulic quick couplers are used for efficiency. With this attachment, switching from one tool to another is accomplished quickly and easily, without the help of a crew to change it manually.
These rippers are the perfect tool for tearing up concrete. They can be used in all weather conditions and can even tear through frozen surfaces with ease.
A tilt-rotator is an attachment that enables the excavator to rotate 360 degrees and tilt +-45 degrees. A grapple function is also included, which enables the machine to complete a broad range of tasks in various conditions.
Excavator size classifications
If your project is small and has a tight area, these compact machines are perfect for you. These excavators can work around buildings easily, making them great for landscaping projects like digging holes for trees. If precision is important for your project, this mini digger can get the job done right with little to no tail swing.
Mini excavators are the most efficient and flexible tools on the market. They are suited for smaller projects that require a small amount of lifting or hauling, and greater precision. They weigh less than five metric tons and are much easier to transport, requiring less fuel for the truck or trailer.
Midi excavators are the most popular size for contractors, as these machines weigh between five and ten metric tons. A midi excavator can dig deeper, move larger volumes, and lift heavier materials than a mini excavator thanks to its bigger engines, stronger components and increased power. They’re also more stable thanks to their larger wheel diameter which means a lower center of gravity.
For the contractors who are performing excavation and rough grading tasks with large quantities of material, this is the most common size of an excavator. Most medium excavators are suitable for any task and they usually support any type of attachment tool.
Medium excavators are typically used on most construction sites. They weigh between ten and twenty-five metric tons and can dig through soil, gravel, sand and many other medium-hard materials. These usually have a maximum digging depth of around 15 to 20 feet. A general purpose excavator is an excavating tool that is designed for use in a variety of applications, such as demolition work or removing trees. They are so versatile because they have a number of attachments which can be used as well as various size buckets that are compatible with the attachment whip assembly.
Large excavators are often used on commercial construction sites and large demolition projects such as shopping malls and large-scale buildings. Weighing more than twenty-five metric tons, they can be difficult to deal with when it comes to transporting and storing, but if you usually have large projects that need heavy lifting or have big demolition projects, then this is the most appropriate size for you to use.
With so many excavators on the market today, it can be hard to know which is best for your project. This complete guide will help you understand what size and type of excavator is needed for your next project.
