Excavator Heavy Construction Equipment – What You Need To Know

What you need to know about excavator heavy construction equipment? For most construction jobs, excavators are a must-have piece of heavy machinery. Excavators, sometimes known as diggers, are used for a variety of tasks including material handling, landscaping, demolition, mining, river dredging, and building.

The Excavator’s Make-Up

A boom, dipper (or stick), and bucket make up an excavator’s anatomy. These parts are connected to a cab that rotates around the home. The majority of houses can rotate 360 degrees. Depending on the manufacturer and the nature of the project, excavators might be equipped with tracks or wheels.

Excavators come in a wide range of sizes and can weigh up to 180,000 pounds. To diversify the equipment, there are numerous alternative accessories for excavators that can replace the digging bucket. The excavator can be used for a variety of tasks by replacing the bucket with an auger, drill, ripper, or rake.

Selecting the Appropriate Excavator for the Job

Assessing what exactly you need the equipment to achieve is the best approach to determine what excavator rental is required for your project. The best equipment for your work will be determined by determining the right size of excavator, the attachments required, and the length of time you require the rental. Instead of trying to fit one piece of equipment into a variety of jobs, it is more efficient for a job to rent the correct size equipment for the job.

What Are the Different Excavator Types?

Excavators are frequently employed in earthmoving projects. However, because to the wide range of popular excavator rental sizes and attachments available, this equipment is suitable for a wide range of excavation operations. An excavator can be found on practically any construction project, from landscaping to the construction of a brand new high-rise skyscraper.

They may be employed in both large building projects and minor backyard improvements because to their size diversity. In Europe, wheeled excavators are popular for operating in urban areas since their wheels are gentler on polished roads and pavement than standard metal tracks.

Hydraulic Excavator vs. Cable Excavator

The distinction between a cable and a hydraulic excavator comes down to how the machine’s pieces operate. In the early 1900s, steam shovels were replaced by cable excavators, which used a network of steel wires and cables to move the major pieces.

Hydraulic excavators work by allowing the driver to control the flow of hydraulic fluid through levers to push and move the cylinders that control the excavator’s boom and bucket.

Different Types of Excavators

Crawler, Dragline, Suction, Skid Steer, Long Reach, Mini Excavator, and Wheeled Excavator are the six main types of excavators available on the market.

Crawler Excavators

The crawler excavator is the most well-known excavator, and it is what most people think of when they hear the phrase “excavator.” It is used for mining, trench digging, and landscape grading. Instead of a track, this excavator is available on wheels.

Dragline Excavators

A larger excavator that clears earth for underwater projects, pile driving, or road excavations using a hoist rope and dragline system.

Suction Excavators

Clears dirt, soil, and debris with water jets and a high-pressure suction. The suction excavator, which is operated from a wheeled vehicle, is utilized for subsurface applications, debris removal, and other delicate excavation jobs.

Long Reach Excavators

The excavator’s arms can reach up to 100 feet with attachments, making it ideal for heavy-duty digging and industrial demolition.

Mini Excavator

Mini excavators, sometimes known as mini diggers, are a compact, smaller variant of crawler excavators that are useful on narrow job sites, job sites with obstacles, and jobs with delicate terrain, such as landscaping. Mini excavators are appropriate for little work because they have no tail-wing capability. Mini excavators are also popular for landscaping tasks around the house and in the backyard.

 Wheeled Excavator

The wheeled excavator is similar to a standard excavator, but instead of tracks, it has wheels. Wheeled excavators are gaining in popularity as a result of their increasing use in city construction.

Excavators’ Attachments

There are numerous small excavator attachments available. For specific operations, renting a specialized attachment might help your machine run more efficiently and smoothly. While there are several more common types of excavator attachments available for both small excavators and regular machines, you can pretty much rent the attachment that best suits your needs.

A bucket is added to a typical excavator, which digs towards the cab and machine. A thumb can be added to this digging bucket, making it easier to lift and transfer contents. There are a variety of buckets that can be used with an excavator.

Two bucket types that can be mounted to an excavator are a rock bucket and a V bucket. A rock bucket resembles a digging bucket, except it has longer, sharper teeth and a narrow V-shaped cutting edge. A rock bucket’s reinforced structural elements enable it to break through strong rock while maintaining structural integrity. Digging trenches is made easier with the V bucket, which is also essential for laying utility lines and pipes.

Excavators can be equipped with augers for digging holes, hammers for breaking up hard concrete and rock, rippers, compactors, rakes, and a variety of other instruments. All of these attachments contribute to the excavator’s ability to be a truly multipurpose machine.

Excavator manufacturers

When renting or purchasing an excavator, there are several different manufacturers to choose. Excavators come in a variety of sizes and kinds to handle projects of all sizes and types.

DOZR has a selection of excavators available for hire. Excavators ranging in size from 18 to 80 tons, as well as high and long reach excavators and wheeled excavators, can all be found here. The following is a list of some of the more well-known excavator brands.

Caterpillar

Caterpillar, or CAT, was created in 1925 when the C. L. Best Tractor Company merged with the Holt Manufacturing Company, which was founded by the same Holt family who invented the continuous-track system.

Caterpillar is one of the most well-known heavy equipment and machinery names, as well as one of the world’s major heavy equipment manufacturers.

In 1972, Caterpillar produced a line of excavators known as the 200 series. Its excavators now have fuel-efficient engines, the most up-to-date safety technology, and are built with productivity in mind. Caterpillar makes a wide range of excavators.

Volvo

Johan Theofron Munktell, then 27 years old, laid the foundations for Volvo Construction Equipment in Eskilstuna, Sweden, in 1832.

Johan was commissioned by the city of Eskilstuna to develop an engineering workshop to help the local mechanical sector grow. Johan built Sweden’s first locomotive in 1853.

At the same period, two brothers named Jean Bolinder and Carl Gherard returned to Sweden from England to start their own business after studying engineering technology.

Johan’s engineering factory amalgamated with the enterprise founded by the Swedish brothers to form AB Bolinder-Munktell 100 years later. This was the company that Volvo bought in 1950.

Volvo is still pushing the limits of construction equipment manufacturing today. Volvo CE said in 2019 that by mid-2020, it plans to develop a line of electric small excavators and wheel loaders.

Volvo manufactures crawler excavators, wheeled excavators, small excavators, and short swing excavators. Volvo’s wheeled excavators are the company’s most well-known product. Compact and medium-wheeled excavators are available with the same attachment possibilities and stability level as tracked excavators.

Komatsu

Komatsu began operations in Japan in 1917 and expanded to North America in 1970. Their H-Series hydraulic excavators were introduced to the American market in the 1960s, a few years before they firmly established themselves in America.

Komatsu’s latest excavators have new engines and hydraulic systems that improve fuel efficiency. The company strives to use the highest quality materials and craftsmanship in the construction of their excavators.

Komatsu has excavators for various types of tasks, from tiny and compact to mining excavators. Mid-range variants, such as the Komatsu PC170LC-11, have 121 horsepower and 2,100 revolutions per minute, with an operational weight of up to 43,115 pounds. Komatsu also makes the PC240LC-10 Super Long Front, which is designed for digging deep ditches or sloping applications and provides a productive and sturdy equipment basis.

The very long front has a broad working range. The PC240LC has 177 horsepower at 2,000 rpm and a maximum working weight of 58,521 pounds.

John Deere & Company is a manufacturer of agricultural equipment.

After inventing the polished steel plow in 1837, John Deere founded his company, which he named after himself. The JD690, the first John Deere excavator, was introduced in 1969. They now produce over 20 distinct excavators with varying sizes, weights, and horsepower.

The 870G LC Excavator, their largest excavator, has a digging depth of 31 feet and a 512 horsepower. Although only certain types of projects would require these skills, it is still really cool. The 75G is a mid-sized excavator with a 15-foot digging depth, 56.9 horsepower, and a weight of slightly under 18,000 pounds.

Excavators’ Potential Hazards and Safety Protocols

Operating any type of big equipment could be dangerous. It is critical to exercise caution at all times and to only operate heavy equipment after having sufficient training. Consistency and adherence to safety rules can aid in the safety of all excavation operations. Here are some tips for driving an excavator safely:

• Without suitable support systems, never dig beneath buildings such as sidewalks.
• Put on a hardhat, a safety vest, earplugs, and respiratory protection.
• Under no circumstances should you dig beneath an excavator.
• Keep the taxi clean by picking up trash and keeping the windows clear.
• When operating an excavator, avoid making quick twists or sudden movements.
• When parking, always lower the bucket and park on a flat surface.
• On hills, move straight up rather than diagonally.
• Make a route for the excavator that is as level as feasible.
• Never exceed a piece of equipment’s maximum weight capacity.
• When driving, lower the bucket closer to the ground to improve vision.
• Before transporting equipment, be sure there are no blind spots.
• Make sure to report any potential safety issues and have any necessary repairs completed as soon as possible.
• Always fasten your seatbelt.
• Before you start digging, double-check your site drawings and phone the local utility agencies.

The most important thing to remember is that you should only operate heavy equipment if you have received proper training and it is safe to do so. There are also certain tips and techniques for unique jobs, such as operating an excavator on a hill, available on the internet. Before agreeing to operate new machinery, always request training.

The Excavator’s Background

The steam shovel was the first machine that looked like an excavator. Next to the modern excavator, this prehistoric dinosaur was a game-changer when it was designed by William Otis, who got a patent for the concept in 1839. Originally, it was installed on railway rails to allow for mobility.

In comparison to a man’s ability to move 12 cubic yards per day, the machine could move up to 300 cubic yards per day. This equipment was used to dig the foundations for early skyscrapers and to build the Panama Canal. As tracked and wheeled equipment grew increasingly prominent in the 1920s, the machine was used and upgraded. The last railroad shovel was delivered in 1931.

The excavator, like the bulldozer and other pieces of machinery, was made up of several sections that had to be put together. Sir W.G. Armstrong & Co. was a British company that invented the hydraulic system that is utilized in today’s excavators.

The first hydraulic shovel, which was more comparable to the one used today than the steam shovel, was patented by Kilcore Machine Co in Minnesota in 1897 and utilised the technology created by Sir W.G. Armstrong & Co. It was designed to use water instead of hydraulic fluid, which is now used.

None of these excavators could spin to the full 360 degrees that the modern excavator can. It wasn’t until the 1960s that a French company called Poclain built an excavator with cylinders and a hydraulic pump that this became a reality. As the first fully revolving hydraulic excavator, the TY45 made history.

The Excavator: Frequently Asked Questions

Is it possible to utilize an excavator as a crane?

Lifting is not an excavator’s job, and it can be dangerous to the machine, the operator, and the surrounding environment. Excavators are occasionally employed as cranes on construction sites to lift and move equipment. It should be done with extreme caution and care. Only an excavator operator who has been well trained in the use of the machine for lifting should attempt to raise with it.

Is it possible to lift a shipping container with an excavator?

Excavators aren’t designed to lift anything. They are, nevertheless, employed to lift and transport equipment on the job site. An excavator can have a range of capacities, including lifting a shipping container, assuming the correct sized equipment is rented for the job. The main thing to remember here is that you’ll need to know the container’s weight and size to make sure you’re using the right excavator for the job.

To raise a shipping container high enough to load it onto something, the excavator’s center of gravity and weight must be sufficient to handle the load. No earthmoving equipment should be used to raise a weight that exceeds its rated capability.

What is the maximum depth that an excavator can dig?

The depth capability of an excavator is determined by the machine’s size. Excavators with special features, such as a long-reach model, allow you to dig deeper than you could with a conventional excavator.

What is the proper excavator digging position?

Depending on the terrain, the size of the equipment, the location of the dig site, and the nature of the operation, the correct position for digging with an excavator will vary.

Taking the time to organize ahead of time is the best approach to ensure a successful dig. Once the dig is underway, planning where the scoop pile will go and where other needed items will be staged will keep the excavation safe. The productivity and efficiency of a job will be ensured by reading site drawings to identify underground risks such as wires or pipes. To align the first dig, take the time to paint lines before digging.

All of these processes contribute to the creation of a safe working environment, which is the first step toward proper excavator digging.

What’s the difference between a backhoe and an excavator?

While a backhoe and an excavator can both be used to dig, they are two different machines with different roles. A backhoe is a considerably smaller piece of equipment with a conventional tractor body on the back end and a bucket or other attachment on the front end. On the front end of an excavator, there is merely a digging bucket – or other attachment.

The backhoe’s rotation radius is 200 degrees, while the excavator’s is 360 degrees.

Backhoes are extremely flexible machines that may be used for a variety of tasks including digging, loading, lifting, pushing, and hauling. They are frequently wheeled pieces of machinery. Excavators are typically used for excavating, heavy lifting, landscaping, and demolition. Although wheeled excavators are becoming more popular, the majority of excavators are still tracked.
