Construction work is a much-needed career. It is important to understand and be familiar with the different types of construction equipment. Excavators are an essential piece of equipment for most construction projects. Excavators are used for many different types of jobs. In this article, we will discuss excavators, types of excavators, and hydraulic excavators.

What is an Excavator

Excavators are made up of several different parts. These include boom, dipper, and bucket. All these components of the cab sit on a rotating house. To increase visibility, most excavator cabs rotate 360 degrees. Depending on the manufacturer and nature of the project, excavators have tracks or wheels. Excavators come in a variety of sizes and classes. They can weigh up to 180,000 pounds. An excavator can be diversified by other attachments to take the place of a digging bucket. For example, you can swap out the bucket for an auger, drill, ripper, or rake. Excavators can be used for many jobs.

Types of Excavators

There are six types of excavators available. These include crawler excavators, dragline excavators, suction excavators, long-reach excavators, mini excavators, and wheeled excavators.

Crawler excavator

The crawler excavator is most commonly used for projects such as mining, trench digging, and landscape grading. Crawler excavators have tracks that can travel on a job site. They are better for rough, uneven terrain. Crawler excavators are incredibly powerful machines and have hydraulic power.

Dragline excavator

Dragline excavators are a larger type of excavator that uses a hoist rope and dragline system. They are often used to clear dirt and soil for underwater projects, pile driving, or road excavations. Dragline excavators are generally transported in separate pieces to a job site because of their awkward size. They are assembled at the site and are generally used for larger job sites and projects.

Suction excavator

Suction excavators are used to clear dirt, soil, and debris using water jets and a high-pressure vacuum. They are wheeled-operated excavators. Suction excavators are often used for underground applications, debris cleanup, and other delicate excavation projects.

Long reach excavator

A long-reach excavator has arms that extend up to one hundred feet with attachments. Because they reach further than most other excavators, they are used for heavy-duty digging and industrial demo projects.

Mini excavator

Mini excavators are a compact, smaller version of the crawler excavator. They are useful for narrow job sites or job sites with obstacles. Mini excavators are also used for jobs with delicate terrain such as landscaping. They are ideal for small jobs because they have zero tail-wing compatibility. Mini excavators are often used for DIY landscape projects.

Wheeled excavator

A wheeled excavator is the same as a regular excavator. The only difference is that rather than being on tracks, it is on wheels. 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 in city projects.

Hydraulic Excavator

A hydraulic excavator or digger, is a large vehicle that is designed for excavation and demolition purposes. Hydraulic excavators consist of a chassis, boom, and bucket, and move via tracks or wheels. They range in size and function. Hydraulic excavators weigh between 3,000 and 2 million pounds and their range is between 19 HP and 4,500 HP. Hydraulic excavators rely on hydraulic systems.

Hydraulic excavators are used for a wide variety of projects. They are used for demolition purposes. However, even the smaller models can also demolish buildings. Hydraulic excavators also move large amounts of material such as minerals from one place to another. They are used alongside bulldozers and loaders in a construction zone.

There are several advantages to hydraulic excavators. They are small enough to work on specific tasks within a project area and can usually be transported from one project to another by either being towed or carried on a large truck. Also, many different attachments can be used on hydraulic excavators. These attachments include a mallet for demolition purposes, a blade for scraping, or a grapple for picking up objects.

There are also disadvantages to hydraulic excavators as well. They are heavy vehicles and cannot simply be driven across large distances or on non-reinforced roads. Hydraulic excavators use a large amount of fuel which can make them very expensive to operate. Also, hydraulic excavators can be difficult to repair due to their large size and many moving parts.

Construction Excavation

Construction excavation is essential to the construction process. It is the process of removing soil and rock from a specific area before pouring a foundation. Excavation in construction also involves leveling the ground and preparing it for the construction of a building or structure. Construction excavation is also used to dig trenches to install underground utilities, such as water and sewage pipes, electrical cables, and gas lines. This helps to ensure that the utilities are properly installed and functioning and that they do not interfere with the construction process. Excavation is used to uncover artifacts or other objects of historical or archaeological interest. This can provide valuable insights into the history and culture of the area and can help to shed light on the lives of the people who lived there.

Before beginning a project, it is important to carefully plan and design the project. Excavation can be labor-intensive depending on the size of the project. Be sure to take into account the type of soil or rock being removed, the location of the excavation site, and the potential impact on the surrounding environment. Overall, excavation is an important process that enables us to uncover an area’s hidden history and build the foundations for new construction projects. It is a challenging and demanding field of work, but it can also be incredibly rewarding, providing valuable insights into the past and helping to shape the future. Proper planning and execution are essential to ensure the safety of workers and the integrity of the site.

Finally, choosing the right excavator for your construction project depends on various factors. Consider the size of the construction project you are doing. Whether you are renting or buying construction equipment, plan carefully and use the correct equipment. This will help ensure the success of your construction project.

Working as a heavy machine operator is a varied career, every new site or project is different, not just in surroundings, but the machines that you can be operating. When we think about the different machines that are found in today’s industry, there are huge differences in size and ability, but what do they all do?

Skid Steers

Although they come in several sizes, skid steer loaders are some of the smaller machines you regularly see on sites. Extremely popular, these multi-use machines are primarily used for loading material onto trucks, with the bucket able to be lifted high over the operator’s cab. Today there are dozens of attachments available for these machines, including forklifts, planers, augers, and so on, meaning that these small but versatile machines are found on nearly every site you will visit today. For rough or muddy conditions, you will often see tracked versions, the track loader, used in similar ways.

Excavators

Whether a standard, large excavator, or the smaller compact type, excavators, or track-hoes, are perhaps the most recognizable heavy machinery around, and on most sites, a full-size excavator will be one of the largest machines in use. With its long arm and bucket, the tracked vehicle is designed to lift or dig material, and transport it to another point, be that a different area or loaded onto a truck. The tracks provide traction that makes them really suitable for rough terrain, and you will often find these machines fitted with tree shears or specialized grapples for removing trees on logging sites. The smaller, mini machines are very popular for small construction jobs, working in backyard plots or other restricted access areas.

Backhoe

Built to dig, carry and load material, the backhoe is a versatile machine common on almost any site. With a backhoe arm at the rear, essentially a smaller version of the excavator’s arm, and a loader bucket in the front, the backhoe can carry out the tasks of two other machines at once. In size, it is much bigger than the skid steer loaders and can carry larger loads, but smaller than an excavator, although this makes it more maneuverable for precise excavation work. As a do-it-all machine, a backhoe is one you will find on almost any construction site in the country.

Dozers

Tracked for the ultimate versatility in any conditions, dozers are designed to move soil or rock, by pushing it. Size depends on horsepower, some dozers can be extremely large, depending on the amount of material that is needed to be moved and the site itself. Dozers can often be fitted with extra equipment in addition to the blade at the front that is used to push the soil and rocks, with a ripper attachment at the rear used for moving rocks that are embedded into the ground, and often a winch, which can be used for removing stumps or other obstructions.

If you want a long-lasting career that pays well, try heavy equipment operations. You can learn to operate virtually any type of heavy equipment in use today on construction sites all around the world. The most popular and rewarding type of heavy equipment can be learned in one course. Here are 7 types of heavy equipment you can learn in one training class at Associated Training Services:

1. Backhoes – A backhoe is used for excavation. It consists of a bucket on the back end of an articulating boom. You’ll often see them on construction sites and are used for digging ditches and trenches. If you want bigger holes, use an excavator.
2. Wheel loaders – Wheel loaders are large pieces of equipment with bigger buckets than backhoes and are used to carry material from one end of the construction site to another. They are close cousins to front-end loaders.
3. Bulldozers – The bulldozer is the workhorse of the construction site. It consists of a large blade and is used for pushing dirt, soil, sand, rock, rubble, and other debris around the worksite. When you just want it out of the way, use a bulldozer.
4. Excavators – When you really need a big hole dug, use an excavator. See how an excavator compares with a backhoe in the video below.

1. Road graders – A road grader has a long blade on it and is used to flatten surfaces, such as gravel roads and construction sites.
2. Dump trucks – When you have a lot of dirt, soil, rock, and other substances to move, use a dump truck.
3. Skid steers – A skid steer, also called a skid steer loader, is a small piece of equipment that allows you to add different attachments to the front for hauling, moving, and lifting things. Watch this fun video of a skid steer in action.

Trenching, or digging a ditch, may look like it is a simple process that anyone with a shovel or a rented backhoe can do. But that mistake causes many accidents and even deaths every year. According to OSHA (Occupational Safety & Health Administration), “the fatality rate for excavation work is 112% higher than the rate for general construction.”

Trenching Safety

Here are the four top causes of injury, according to OSHA’s Trenching & Excavation eTool:

1. no protective system
2. failure to inspect trench and protective systems
3. unsafe spoil-pile placement
4. unsafe access/egress

The eTool has simple guides for avoiding each of these, but reading some information is not the same thing as being trained by qualified instructors. These teachers have the credentials that result in certifications future employers and insurance companies respect.

Why Training Is Better Than Teaching Yourself

Excavators do a dangerous job. When the consequences of making a mistake are things like injury or death, it’s better to begin the learning process in a classroom with expert teachers who can give you the benefit of their experience. You can learn about the types of mistakes that can be made and what will happen. Then, after the “head” knowledge is there, the “seat-of-the-pants” knowledge can be added in an environment designed to keep mistakes from being deadly.

Everyone makes mistakes when learning how to do something even trenching. That’s why some teachers say that F-A-I-L stands for “First Attempt In Learning”. Teaching yourself certain skills is a very good idea, and reading up on OSHA guides to a career you are interested in is a good idea, too. But if you are interested in operating heavy equipment, particularly those that are used in excavating, the best thing you can do is invest in credentialed training like that offered at ATS Heavy Equipment Operator Training School.

According to OSHA, “Excavating is recognized as one of the most dangerous job in construction operations.” This is because excavators dig holes and trenches that can easily collapse if proper safety procedures are ignored or the soil is not analyzed correctly. An excavator operator has a very important job, one that requires a lot of knowledge and skill.

It may not look like the traditional excavator has changed much, but there are a lot of things happening in this part of the heavy equipment world. Many machines are being built as hybrids to save fuel, and each company tries to build the latest operating abilities into their product. But however fancy the excavator is, it’s only as good as the operator who runs it.

Excavator Operators Change Their Foundation

Since every excavator is changing the very ground it operates on, that operator needs to be able to assess changing conditions and respond in the best way possible. Whether it is digging a trench for a new community sewer system, clearing ground for a new high rise, mining, logging, disaster clean up, or something else, and excavator is one of the machines you will see being used. In each case, there are swiftly changing conditions and an operator who must know what to do.

Because an excavator operator does such a dangerous job, it’s very important to be trained properly. At ATS Heavy Equipment Operator Training School there is the experience of decades combined with the ability to adapt to the industry standards of the future. We are the recognized leaders in training heavy equipment operators for all the industries who rely on this important skilled trade.

You get the knowledge that gives perspective on a situation along with the experience that provides the skills that will continually develop on the job to make even the most dangerous jobs ones that can be done safely and professionally.

Do you know how a lot of the work used to be done in this country? By teams of men with shovels, spending their lives digging tunnels and trenches. Many of the roads and railroad tracks still in use today were first established by a lot of shovels working hard to do the job. The guy using the shovel had to learn the best technique so he could move a lot of dirt without hurting himself or others. It took muscle, intelligence, and skill to keep moving that shovel every long day and get the job done.

Today, an excavator can do the work so quickly and efficiently you’d think the ghosts of those guys with shovels would be standing around in awe. Some machines are small enough to be towed by a car, and other excavators are able to scoop several tons in one big bucket, but they all are operated by someone who learned the same basics in training.

Every excavator operator learns how to operate the equipment safely, how to read the soil and understand site plans, and how to identify problems during maintenance so little issues don’t turn into big ones. It’s a lot different than working a shovel although those guys had to learn safety skills and techniques, too. Today’s excavator operators still need intelligence and skill to get the job done. ATS Heavy Equipment Operator Training School can get you ready to run an excavator in an entry level job within a few weeks, and you can develop the experience and skills you need to further your career. Having the basic training and certification gives a solid foundation to build on, just like those shovel-wielding men in the past built the foundations of the roads we use today.

The heavy equipment industry can be quite complex when it comes to different types of machinery. Take the humble excavator. This is a piece of machinery that has a bucket at the end of a boom used to dig holes. Or is it? The backhoe is an excavator that has been modified through the addition of a loader at one end – effectively, two machines in one. Different industries have specialized equipment which, whilst bearing the name excavator, look very different to the traditional excavator found digging trenches.

In the mining industry, there are bucket excavators where the name refers to a large wheel that has buckets attached. This machinery continually cuts through earth and rock, a little like a large grinder. A smaller version is sometimes used to dig trenches for underground services – this is known as a continuous excavator. The mining industry also uses an excavator that is similar to the traditional machine, however, it is much larger, and rather than digging holes, is used to scoop large amounts of ore to dump into huge trucks.

There are older excavators that use cables to control the boom and bucket. These are fairly slow workers, however, they are very reliable. Modern machinery achieves the same control using hydraulics. Hydraulics can be maintenance heavy as the equipment gets older – the slightest leak in a hydraulic line will weaken the machinery’s ability to work.

Traditional excavators have changed a lot over the years. The bucket is no longer fixed – it can be removed in minutes and range of different attachments installed – again, in minutes. These attachments can do anything from breaking up concrete to digging large post holes. Heavy equipment is not as simple as looking at a bulldozer, grader, loader or excavator – there are so many different versions of each equipment. Fortunately for new operators, it’s the more traditional equipment that they’ll be using. After completing heavy equipment training, and as you gain experience, you can look at some of the more specialized machinery.

If you want a successful career as a heavy equipment operator, then I suggest you steer clear of being a one act pony. Employers are increasingly looking for heavy equipment operators who are multi-skilled. It’s not just across the heavy equipment range either. Employers are looking for operators who can drive trucks and on occasion operate cranes. The question becomes now – are you a multi-skilled heavy equipment operator, multi-skilled truck driver, or multi-skilled crane operator?

You may think I am being pedantic in those titles, however, your description will depend on what your primary job is. The job listings from last weekend included vacancies for multi-skilled crane operators, and multi-skilled heavy equipment operators. The demand is there, and if you have a range of skills, then you are going to be more employable.

For most people who are just entering the heavy equipment industry, learning to operate a variety of machinery is a must. Whilst you may have a preference for one type, don’t just focus on that one type. By all means seek a career operating your choice of equipment, however, if given the opportunity, keep your skills up on as many different machines as possible. Demand for heavy equipment operators runs in cycles – one month there will be a demand for bulldozer operators, next month it could be excavators, or grader operators, you need to be prepared for all opportunities that come your way.

The training program at ATS Heavy Equipment Operator Training Schools is to provide access to a wide range of machinery. As a student, you will have the opportunity to learn how to operate these machines and to gain valuable practical time in the operator’s seat. At a later date it may be advisable to look at either truck driving (obtaining a CDL) or crane operator certification (or both) – this will expand your employment opportunities and perhaps even your paycheck.

Mention heavy equipment and most people think of a bulldozer. That probably relates back to most people’s childhood where a bulldozer was an essential toy in every sandbox. In the adult world, bulldozers are still one of the most popular choices when it comes to heavy equipment careers.

Unfortunately, or perhaps fortunately, depending on your mind set, many employers see life differently. Rather than employing a bulldozer operator, their preference is to employ a heavy equipment operator – in other words, an operate who is skilled across a range of heavy equipment. That’s not to say you can’t spend your whole working life as a bulldozer operator. Having those extra skills does come in handy when times are quiet.

In truth, there is a certain sameness coming into heavy equipment. The levers, buttons and pedals are very similar across most heavy equipment. Bulldozers run on tracks, but then, so too do many other types of heavy equipment. Bulldozers have a range of attachments that can be added to the rear – so too do excavators and backhoes. Most heavy equipment machinery now utilizes modern technology such as onboard computing, GPS and laser technology.

The big difference between each type of machinery is the type of work done. Bulldozers typically push dirt around. Excavators excavate, loaders load and graders grade. Modern operators learn how to perform each job, how their heavy equipment interacts in various environments and with different soil types.

Bulldozers are still the number one choice for many new operators to the industry. However, if they have attended a good heavy equipment operator training school, then they will have the range of skills that many employers are now looking for.

Much has been said and written about heavy equipment safety, however, it not a new subject. Safety has always been at the core of any heavy equipment training – there’s just hasn’t been the focus that we now see. In the past, it was considered a part of your training, not as a separate subject.

As an example, an excavator operator has always been taught to check their environs before operating their equipment. Looking up, looking around, and even looking down is not new – it’s always been there. The difference now is that operators are assessed on their specific knowledge of heavy equipment safety and because of that, it has become a separate subject area.

When you compare accidents and serious injury/death rates between now and twenty years ago, there’s no argument that specialized safety training has helped to decrease these numbers. Employers have been given the responsibility (some would say burden) of ensuring that all workers are trained to a minimum OSHA standard. When looking for heavy equipment training, it makes sense to check that OSHA training is included in your training program. Without this training, your employment prospects may be limited – you will need to find an employer who is willing to take your through an equivalent safety training program.

Safety in the workplace is an important issue nationwide, not just in the heavy equipment field. Pen pushers in their glass towers are required to have some form of safety training, even if it only involves fire drills. When it comes to heavy equipment operations, it’s important to remember that your equipment is large, it’s heavy, and it’s deadly if not used safely – deadly to both those around the equipment, and in many cases, to those operating the equipment.

Heavy equipment safety has always been an important component of training – today, safety issues are clearly documented and you are expected to have a sound knowledge of these issues.
