The construction, building and mining industries rely on excavators for heavy-duty applications, including digging and hauling materials. Excavators provide an excellent way to increase productivity and efficiency at your job site while reducing operating costs.
The right excavators will have enough power and strength to meet the needs of your applications while operating at maximum efficiency. In this guide, you’ll learn about the different types of excavators, excavator weight classes and different excavator sizes.
You have many flexible options for excavation models and equipment types to meet the needs of your applications. Different types of excavators or diggers are better suited to heavy-duty jobs, while others are ideal for less intensive tasks. Some of the most common excavation equipment types and their uses include:
Standard excavators, also known as crawler excavators, use a boom, stick and bucket arm attachment at the front of the equipment. These excavators are designed to handle the bulk of the work and are often used in heavy-duty construction, mining, farming, landscaping and other industries.
The bucket arm attachment extends to dig through soil or other materials and retracts to lift materials. The cab is capable of rotating 360 degrees, making it easier to dig and dump different materials. These excavators use rotating tracks to provide traction and stability, which allows them to navigate steep slopes or rugged terrain. Standard excavators also have tracks that exert less ground pressure, making them a popular option for various jobs.
You can choose from different excavator sizes to suit your applications, whether you need a machine that can fit into higher spaces or something that works in heavy-duty situations. You can also choose from different bucket sizes to help you complete other tasks at your worksite, such as moving debris or materials, demolition, trenching and hauling.
While standard excavators run on tracks, these excavators run on wheels. Wheeled excavators have the same capabilities, size options and general appearance as standard excavators.
Their wheels allow them to maneuver on tough terrains, including asphalt, concrete and uneven soil. Wheels have a higher ground pressure that reduces their traction, so they’re not suited for slopped or hilly terrain applications. Instead, these excavators are used more often for urban construction or roadwork.
You can generally drive wheeled excavators from one job site to the next without needing a trailer, saving time and money. Wheeled excavators work best on flat worksites and can improve speed and maneuverability when digging and transporting materials.
Long-reach excavators are similar to standard excavators but use an extended arm and boom. These excavators are best suited to jobs with areas that are hard to reach, as they can have a working range of up to 100 feet. Long-reach excavators are often used during challenging and tight excavation or demolition jobs.
Dragline excavators are heavy-duty equipment best suited to large applications such as harbor construction, canal dredging and strip mining. These excavators are larger than standard excavators and are often assembled on-site.
Dragline excavators use a bucket system that drags along the surface with chains and wire rope. The bucket is attached to the boom and is hoisted after excavation. The excavator rotates to the dump location and releases the bucket to dump the excavated materials.
Backhoe excavators are often confused with crawler excavators. Backhoe loaders have the boom attached to the back of the equipment rather than the front. The front of the backhoe excavator features a bucket and blade that pushes, levels and moves materials. Backhoes can also only rotate 200 degrees instead of a total of 360.
Despite their limited rotation, choosing a backhoe loader with excavator attachments has some benefits. Backhoe excavators are more versatile and can simultaneously accomplish digging tasks and soil leveling and grading. These machines can also quickly move larger quantities of materials and can be paired with work tool attachments to increase their versatility.
Hydraulic shovels are suited for heavy-duty tasks within the mining industry but can also work for hydro excavation and intense singing processes. These machines feature powerful lifting arms and a large bucket for carrying soil, minerals, rocks and other heavy materials. There are different orientations for hydraulic shovels, including the bucket facing the machine’s cab or a bucket facing away from the cab, based on the needs of your operators and applications.
Suction or vacuum excavators can help loosen soil and remove it from your worksite, which makes them ideal for excavation and trenching jobs. These excavators utilize water pressure to loosen soil and use a suction pipe for removal. Suction excavators suit applications requiring delicate, precise soil extraction without risking damage to any surrounding ground or underground components.
Standard excavators are versatile machines on their own, but work tools and attachments can extend these capabilities even further. If you are looking for an excavator that can do it all, look for one that supports a variety of work tools. Here are a few popular excavator work tool attachments to increase the productivity of your excavator.
Adding work tool attachments to your excavator enables you to tackle various tasks with a single machine.
Excavators come in various sizes to suit every project, from backyard landscaping to large-scale commercial construction. Understanding the benefits and challenges of different sizes of excavators can help you make an informed decision about the right size excavator for your job. There are three primary excavator size classes according to the machine’s weight which can you can find in the following excavator size chart.
Mini or compact excavators include any excavating equipment weighing less than 7 metric tons. These excavators are best suited for tight job sites where standard-sized excavators can’t fit or maneuver properly.
You can use mini excavators for small landscaping jobs that require creating trenches for infrastructure or digging holes for trees. Operators can use mini excavators around structures because they have zero or near-zero tail swings. Additionally, mini excavators are more precise than larger alternatives, making them suited to jobs where you need to install underground pipes or gas lines.
Mini excavators are easier to transport than standard or large excavators. These machines also require less fuel, which helps reduce operational costs. Further, because mini excavators are lighter, you can use them when operating on soft ground or finished job sites without risking damage. However, it’s essential to remember that mini excavators don’t have the same power as standard or large excavators and may not have the capacity for specific jobs.
Standard-sized excavators weigh between seven and 45 metric tons. These versatile excavators are the most common size for commercial construction projects and offer enough power and hauling capacity to handle tough jobs. Many hydraulic standard excavators can also support a variety of work tools, so contractors can customize their excavators to suit their project needs.
Standard excavators are still easy to maneuver and can significantly increase productivity on a job site. However, the larger size and weight of standard excavators can damage soft soil or finished sites. Some excavators can also be challenging to use in tight spaces, depending on their size, reach and tail swing. Standard excavators can be heavier than other types, creating storage and transportation challenges.
You may sometimes see standard excavators broken into two excavator weight classes — small and medium excavators. Small excavators are those at the bottom of this size class that weigh between 7 and 10 tons. The small size and low tail swing of midi excavators mean they are helpful for many of the same tasks as mini excavators, but offer more power, reach and dig depth.
Large excavators can weigh more than 45 metric tons. These weighty machines are best suited for heavy-duty work, such as commercial construction or demolitions. You can use large excavators to dig foundations for large structures like apartments or shopping malls. Large excavators can also be used to move large amounts of soil for civil engineering processes.
Transportation and storage can be challenging with larger excavators but may be worth the investment if you need to tackle a heavy-duty excavation project.
There are many options for excavator types and sizes, and choosing the right excavator depends on numerous factors. You’ll want to find an excavator that has enough power and strength to efficiently complete different tasks at your job site while lowering operating costs.
If you rent an excavator for a single project, evaluate the requirements and work site when choosing your excavator. If you are purchasing an excavator for long-term use, consider the types of projects your company typically takes on. Choose an excavator that will meet your standard job requirements and perform well on the sites where you most often work. To make the most of your investment, look for an excavator that can keep up with your company’s growth in the future.
Consider these factors when determining what size excavator you need.
First, consider the size and layout of your job site. Will you work in a small area with tight spaces and obstacles to navigate or enjoy a wide-open plot of land with no interferences?
If you work in a small space or on a site with many hazards, a compact mini excavator may be the right choice. A smaller excavator may also be a wise choice if your job site has a lot of underground obstacles, such as pipes and gas lines. Mini and small excavators will have smaller buckets and more precise controls to safely avoid underground hazards while excavating efficiently.
If your job site has more maneuverable space, you can use a standard or large excavator comfortably. However, remember to account for future hazards that may appear as your construction project progresses.
The tail swing of an excavator also impacts how easily it can navigate in tight spaces. Larger excavators typically have a larger tail swing, requiring more counterweight to remain balanced. This rear extension can pose problems when working near walls or buildings and harm workers if not operated safely.
Many mini and small excavators offer zero or near-zero tail swing, so they can rotate safely without damaging surrounding trees or structures. Excavators with zero tail swing are popular for urban or residential work sites. However, excavators with zero tail swing typically have a larger footprint and tracks that are wider apart to provide stability while turning.
Different types of excavators work better on various terrains. Tracked excavators offer excellent traction and stability on hilly and soft ground, while wheeled excavators work best on hard and flat surfaces. However, the weight of an excavator also impacts how well it performs on specific terrain.
Large and standard excavators can exert a lot of pressure and tear up a job site if the ground is weak. For some jobs, this may not be an issue if the earth gets leveled later in the construction project. However, working on a finished site, such as a backyard or other residential space, requires greater care to prevent damage to the terrain. Mini excavators are safe to use on finished sites without harming the ground.
When considering the weight of an excavator, account for the maximum operating weight rather than how much the machine weighs alone. The operating weight will include the weight of the excavator operator and the load the equipment will haul.
After accounting for your work site conditions, consider the typical tasks your excavator will need to perform. You should pick an excavator size that can handle your digging, lifting and hauling needs without struggle or sacrificing efficiency. If purchasing an excavator for long-term use, look at the requirements of past projects to get a sense of your future needs. Account for any potential growth, and choose an excavator that will suit your company’s needs for years to come.
Here are a few project requirements to consider when choosing the right excavator size.
An excavator that’s the right size will be able to meet all your project requirements while safely maneuvering around your job site. If an excavator cannot match your job needs, consider upgrading it with a new boom or bucket to extend its capabilities.
Another important consideration when choosing between the different sizes of excavators is each size’s transportation and storage requirements.
Transportation of large and standard excavators can be expensive, requiring special permits and equipment. If you plan to transport your excavators on your own, ensure you have the vehicles and trailers to do the job and drivers with the required licenses for moving heavy equipment. You may also work with an equipment transportation company to reduce the transportation costs of carrying your large excavators. Standard-sized trailers can move mini excavators, but depending on your state, you may still require special permits or licenses.
If you plan to purchase an excavator for long-term use, ensure you have the appropriate storage facilities for the size of the excavator you choose. You can also rent a storage space during the offseason to cut expenses. For infrequent use, renting an excavator instead of buying one may help you save money on storage and transportation costs.

This article will explain the different sizing categories of a mini excavator, common jobs they are used for, how they compare to standard excavators, how to choose the right mini excavator for jobs and more. If you are curious about anything to do with a mini excavator, this is the article for you.
The mini excavator has capabilities similar to an excavator, with the added benefit of being able to work in small spaces.
The mini excavator goes by many names including the mini ex, small excavator, mini digger, mini hoe and compact excavator. No matter what you call this machine, the small compact excavator is small enough to get any type of precise digging done.
A boom, dipper – or stick – and bucket connects to a cab that sits on a rotating house. Most houses can rotate a full 360 degrees. Mini excavators can be fitted with either tracks or wheels.
Mini excavators are categorized as having an operating weight under 4,535 kg (9,999 lbs). The smallest mini excavator can fit through a doorway. Their bucket sizes can range from 12 – 24 inches and can always be replaced with another attachment to tackle any job. Many companies, however, label their mini excavators as compact excavators. Compact excavators usually have a cut-off weight of 18,000 lbs. However, most companies often group both mini and compact excavators under the same category.
Most mini excavators are used for light demo, material handling, stump removal, construction projects or landscaping.
Because of these capabilities, mini excavators are often used for smaller projects in construction and landscaping. These include:
Installing pools and hot tubs
Demoing of small buildings
Repairing sewer lines
Tree harvesting
Grave digging
Home renos
Landscaping projects
Roadside applications
General digging projects
How to Choose The Right Mini Excavator For Your Project
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. As a result, your job can actually become more efficient. It can be 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.
The Mini Excavator VS Standard Excavators
The mini excavator and standard excavator both have a time and place for best use. This means that the mini excavator can be better suited for certain jobs over a standard excavator. It is always important to choose an equipment type based off the project demands instead of personal preference. This helps to prioritize efficiency and productivity in all projects.
Mini excavators are smaller and lighter meaning they offer reduced top-ground damage and reduced track marks. Similar to standard excavators, mini excavators are also available with tracks or wheels depending on the nature of a project and terrain of a site.
Beneficial for Busy or Compact Project Sites
The small size of mini excavators make them more popular for high traffic work sites or for working around other equipment types. Not only can they drive over parking lots with less hassle but are much easier to transport between projects. Even though they are lighter it is always important to check that a trailer can support the weight of a piece of equipment before loading it.
Mini excavators are usually used for less intense projects than a standard excavator meaning that they have a longer life span. Just like standard excavators they can be fitted with all types of attachments to diversity their abilities.
Renting a mini excavator on a per-project basis can be much more efficient than trying to use one standard-sized excavator for all jobs. Search for mini excavators on DOZR to see the variety of sizes and attachments available near you.
Attachments for mini excavators include a dozer blade, hammer, auger, grapple or breaker and many more. All of these attachments - and more - are available for rent. A more complete list of mini ex attachment include:
Buckets and Couplers, including…
4-in-1 bucket
ditching bucket
V-Bottom bucket
trapezoid bucket
Power tilt pin grab
Power wedge, and more
Mini excavators can also be fitted with dozer blades to help them move materials around site. Further, a dozer blade attachment can add a stability factor to the equipment, especially if it’s a wheeled mini excavator. Mini ex attachments replace the bucket at the end of the boom which helps to increase the versatility of the equipment.

The Hitachi compact excavators are small and mighty tools that can be helpful on any job site.
Potential Hazards & Safety Protocols for Mini Excavators
Operating any kind of heavy equipment could pose a safety hazard. It is important to always be careful and to only operate a piece of heavy equipment after receiving proper training.
The US Occupational Safety and Health Administration (OSHA) requires that any employees tasked with the operation of heavy equipment – mini excavators included – are efficiently trained to ensure safe operation of the equipment. Always ask for training and never operate a piece of heavy equipment that you have not been trained on.
Many safety protocols for mini excavators mimic those for a standard excavator. They include but are not limited to:
Wearing a seatbelt
Cleaning and adjusting mirrors before using the equipment
Never transport riders in a bucket
Surveying job site plans and the status of a work area before starting to dig
Avoiding sudden movements
Never dig underneath a mini excavator
Wearing high visibility clothing, hard hats, ear protection, and face mask when applicable
Driving on a route that is as flat as possible
Avoiding rough and uneven terrain
Familiarize yourself with the max weight and lifting restrictions of a mini excavator before attempting to lift material or a load. If at any point it does not feel safe to operate a mini ex or any other kind of equipment stop and speak to a supervisor.
The History of the Mini Excavator
The history of the mini excavator starts off with the creation of the excavator which came from the first ever steam shovel.
The steam shovel was invented by William Otis. The equipment would travel on railway tracks and could move up to 300 cubic yards of material a day. This machine was used to build the Panama Canal and dig the foundations of early skyscrapers. The last steam shovel was sold in 1931 and hydraulic shovels took over.
Sir W.G. Armstrong & Co invented the first hydraulic system in 1882 which was then used by Kilcore Machine Co to develop the first hydraulic excavator 15 years later.
There are two separate incidents noting the creation of the mini excavator. There is the “first” mini excavator – ‘the smalley’ – and the first self-propelled mini excavator – the YNB300.
The smalley mini excavator, which would be moved by using the front digger to lift and drag itself across the ground on its back wheels. Image borrowed fromEarthmovers Magazine.The Smalley Mini Excavator
Invented by Richard Smalley, this piece of equipment is credited with the very first mini excavator. With no actual engine and sporting only two wheels on a single axis, the Smalley excavator moves by the operator using the digging arm to pull itself forward on the two wheels.
These compact pieces of equipment were great for tight spaces and smaller jobs. Because they were self-walking (or could be towed behind another piece of equipment for longer journeys) they were very cost-effective. Richard Smalley invented this piece of equipment in 1959.
Yanmar introduced the first diesel powered self-propelled mini excavator in 1968. Founded in Osaka, Japan in 1912, the company specialized in diesel engines and also makes fishing equipment as well as heavy machinery. In 1933 Yanmar worked on producing the world’s smallest diesel engine. This invention is what most likely lead to the creation of a small, compact, mini version of the excavator.
A mini excavator can be used for removing tree stumps. Using the right sized mini ex and having the right attachments to add help to make a mini excavator a great tool for a variety of jobs.
A backhoe features a backhoe digger on the back and a loader or other attachment on the front. A mini excavator is a small excavator with just a single digging arm on the front.
In a backhoe, the operator seat within the cab swivels 180 degrees to allow for the operation of the equipment either at the front or back of the tractor. A backhoe is used for a variety of jobs like digging, lifting, moving, grading, etc.
A mini excavator has one single arm with a bucket – or other attachment – on the end. The entire cab rotates and is mostly used for digging.
Yes, mini excavators can be rented. Search construction equipment rentals on DOZR to see the variety of mini excavator sizes that are available.
