Renting an Excavator Near You
Excavators are an essential piece of heavy equipment for most construction projects. Often referred to as diggers, excavators are used for all kinds of jobs like material handling, landscaping, demolition, mining projects, river dredging and construction.
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, dril, ripper or rake the excavator can be used for many different jobs.
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 allow 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 medal track.
Cable vs. Hydraulic Excavator
The difference in the cable and hydraulic excavator comes from how the parts of the machine move. Cable excavators which use a series of steel wires and cables to move the main parts replaced the steam shovels in the early 1900s. Hydraulic excavators work by allowing the driver to use levers to control the movement of the hydraulic fluid to push and move the cylinders that control the boom and bucket of an excavator.
The 6 Kinds of Excavators
There are six different kinds of equipment that also act as excavators.
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 is great for residential projects and small clearing tasks.
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.
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.
Attachments for Excavators
The traditional excavator is fitted with a bucket that digs towards the cab and machine. This digging bucket can be fitted with a thumb that makes it easier to life and move materials. There are other types of buckets that can be attached to an excavator. A rock bucket, and V bucket are two example bucket types that can be attached to an excavator. A rock bucket looks similar to a digging bucket but with longer sharper teeth and a narrow V-shaped edge for cutting. The reinforced structural parts of a rock bucket give it the ability to break through hard rock while still maintaining the structural integrity. The V bucket simplifies the task of digging trenches and is useful for laying utility cables and pipes.
An excavator can also be fitted with an auger attachment for digging holes, hammers for breaking up hard concrete and rock, rippers, compactors, rakes, and many other different kinds of tools. All of these attachments help to make the excavator a true multipurpose equipment type.
Manufacturers of Excavators
There are many different manufacturers to consider when looking to rent or buy an excavator. Most companies make different sizes and models of excavators to accommodate projects of all sizes and natures. A variety of excavators are available for rent through DOZR. There are options to search for excavators ranging from 18 ton to 80 ton as well as high and long reach excavators or wheeled excavators. The following is a look at some more popular brands of excavator manufacturers.
Caterpillar - also called CAT - was founded in 1925 when C. L. Best Tractor Company joined with Holt Manufacturing Company - the same Holt family responsible for the continual-track system. Caterpillar is one of the most recognized brands of heavy equipment and machinery and is one of the largest heavy equipment manufacturing companies in the world.
Caterpillar introduced a series of excavators - called the 200 series - in 1972. Now its excavators feature fuel efficient engines, latest safety tech and are designed with productivity in mind. Caterpillar manufactures many kinds of excavators.
Founded in 1949, the Swiss company Liebherr Group was created by Hans Liebherr. He began building airplane parts and tower cranes and has since expanded the company to digging and mining equipment. Loaders, dumptrucks, telescopic handlers (telehandlers) and excavators are just a few of the pieces of equipment now made by Liebherr. Liebherr also makes bulldozers.
Designed with performance, efficiency, comfort and reliability in mind, Liebherr offers a variety of crawler tractors. The PR 716 and 726 Litronic offer travel speeds up to 11km/h and have operating weights up to 20,000 kg (44,092 lbs). The PR 776 Litronic is one of their largest dozers with an operating weight of 73,189 kg (161,354 lbs).
Komatsu was established in 1917 in Japan and established in North America later on in 1970. Their introduction to the American market for hydraulic excavators happened with their H-Series in the 1960s, a little before they truly established themselves in America.
The modern excavators from Komatsu feature new engines and hydraulic technology which drives fuel efficiency. The company works to build their excavators with the best quality materials and superior craftsmanship.
From small and compact to mining excavators, Komatsu offers a variety of excavators for all kinds of projects. Mid-range models like the Komatsu PC170LC-11 boasts a 121 hp with 2,100 rpm with an operating weight up to 43,115 lbs. Komatsu also manufactures the PC240LC-10 Super Long Front which provides a productive and stable equipment base for digging deep ditches or sloping applications. The working range of the super long front is huge. The PC240LC has 177 hp with 2,000 rpm and has an operating weight up to 58,521 lbs.
It was 1832 in Eskilstuna, Sweden when 27-year-old Johan Theofron Munktell prepared the foundations for the company Volvo Construction Equipment. The city of Eskilstuna commissioned Johan to build an engineering workshop to help grow the local mechanical industry. In 1853 Johan created the Sweden’s first locomotive.
At the same time two brothers named Jean Bolinder and Carl Gherard returned to Sweden from England after studying engineering technology to start their own business. 100 years later the engineering workshop created by Johan merged with the company created by the Swedish brothers to form AB Bolinder-Munktell. It was this company that was purchased by Volvo in 1950.
Today Volvo continues to push the boundaries of construction equipment manufacturing. In 2019 Volvo CE announced the goal of launching a range of electric compact excavators and wheel loaders by mid 2020.
Crawler excavators, wheeled excavators, mini excavators and short swing excavators are all offered by Volvo. Volvo is most well known for its wheeled excavators. With the same options for attachments and stability level as a tracked excavator they offer compact and medium wheeled excavators.
John Deere & Co
John Deere established his company - named after himself - in 1837 - after the invention the polished steel plow. In 1969 the first John Deere excavator, the JD690, was introduced. Now they make over 20 different kinds of excavators ranging in size, weight, and horsepower.
Their largest excavator - the 870G LC Excavator allows for 31ft in digging depth and a 512 hp. Although only specific kinds of project would need these kinds of abilities, it is still pretty cool. The 75G is a mid-sized excavator that still allows a 15ft digging depth, 56.9hp and weighs just under 18,000 lbs.
Potential Hazards & Safety Protocols for 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. Being consistent and following safety protocols can help keep all excavation operations safe. Here are some ways to stay safe while operating an excavator:
- Never dig under structures like sidewalks without proper support systems
- Wear a hardhat, safety vest, ear protection, and respiratory protection
- Never dig underneath an excavator
- Maintain the cab by cleaning up garbage and maintaining clear windows
- Avoid making sharp turns or sudden movements while operating an excavator
- Always lower the bucket when parked and park on a level surface
- Do not travel diagonally on slopes but directly up
- Map out an excavator route that is as flat as possible
- Never exceed the maximum weight capacity of an equipment piece
- Lower the bucket closer to the ground when driving for visibility purposes
- Check all blindspots before moving equipment
- Make sure to report any safety hazards and have any needed repairs performed immediately
- Always wear a seatbelt
- Check site plans and call local utility companies before beginning to dig
The most important point to remember for any operation of heavy equipment is to only do so if training has been provided and it is safe to do so. Always request training before agreeing to operate a piece of new machinery.
The History of the Excavator
The first machine to resemble an excavator was the steam shovel. An ancient dinosaur next to the modern excavator, this piece of equipment was a game changer when it was invented by William Otis who in 1839 received a patent for the design. It was originally fitted on railway tracks to allow mobility. The machine could move up to 300 cubic yards a day compared to the 12 cubic yards that could be moved by a man. This machine was used to build the Panama Canal and dig the foundations of early skyscrapers. The machine was used and updated into the 1920s as tracked and wheeled equipment became more popular. In 1931 the last railroad shovel was shipped.
Much like with the bulldozer and other pieces of equipment, there were various pieces that had to come together to create the excavator. Sir W.G. Armstrong & Co. was a British business that had developed the hydraulic system that would be used in the modern excavator. Designed to use water instead of hydraulic fluid which is used now, this system was invented in 1882, the first hydraulic shovel - more similar to the one used today than the steam shovel - was patented by Kilcore Machine Co in Minnesota in 1897 and used the technology developed by Sir W.G. Armstrong & Co.
None of these excavators could rotate the full 360 degrees that is now associated with the modern excavator. This didn’t happen until the 1960s when a French company called Poclain invented an excavator with cylinders and hydraulic pump. The TY45 made history as the first fully revolving hydraulic excavator.
