The largest excavator in the world, built by the German company Krupp, was spotted at the intersection federal highway in Germany, on the way to their destination - a quarry of a coal mine.
So, 10 facts about the largest excavator:
1. The dimensions of the excavator are large, if not huge, 93.3 meters in height and 211 meters in length.
2. The weight of the largest excavator also strikes forty-five and a half thousand tons.
3. The cost of this mastodon is ~ $ 100 million.
4. The development and design of the largest excavator took 5 years, it took another 5 years to assemble it.
5. It looks like the number 5 is magic for this machine, that's how many people are needed to manage coal mining.
6. The excavator rotor is 21 meters in diameter and consists of 20 buckets, each 530 cubic meters. A 180 cm tall man can stand up to his full height in one of the buckets.
7. The largest excavator moves on 12 tracks, each 3.6 meters wide. 8 of them are installed in front and four in the back.
8. The speed of movement will surprise even a turtle 530 m / h.
9. In one day, this excavator is able to lift 76455 cubic meters of rock.
Often in the city you can see small excavators performing important technical tasks. The excavator is one of the most important species technology. In this article, we will talk about the real giants in this class by answering the question: “What is the largest excavator in the world?”.
Big Muskie
One of the types of this technique is walking excavators, which do not have tracks, but are carried over the terrain with the help of “steps” with support shoes (skis). The largest walking excavator is the Big Muskie.
This giant was created in the distant 69th year of the last century. Since then, no one has been able to beat him in power and volume. Price technical means was sky-high by that measure and amounted to about 25 million US dollars. Its creation took two whole years.
The machine carried its service until the end of the millennium, that is, it worked for more than thirty years. To supply its mechanisms and all electric motors with electricity, high-voltage cables with a voltage of over 13 kilovolts were used.
The excavator consumed electricity on a par with a small settlement (30-40 thousand houses). Two full-sized buses are quietly located in the Big Muskie bucket. For the functioning of the technical means, the work of a crew of five people was necessary.
The mass of Big Muskie is 13 thousand tons, and its dimensions were:
- 68 meters high;
- 46 meters wide;
- 149 meters long.
To date, the bucket of this giant is stored in a mining museum in the United States.
Another category of these devices are mining excavators. They are designed for excavation of rocks from the ground or their loading. The largest mining excavator in history is Bagger 293. For its gigantic size, it even managed to get into the Guinness Book of Records as the largest mechanism in the history of the universe.
The mass of this technical means is over 14 thousand tons. Its length is 227 meters. The machine was designed for quarry digging. Bagger 293 coped with this task perfectly! It took the excavator less than 24 hours to create a hole the size of a football field. Its productivity is 10,000 cubic meters of rock in one hour. The monster works non-stop, 24 hours a day with a turnover of work crews. Its maintenance requires the efforts of five people.
The power required by the machine for operation is about 16 kilowatts. The volume of the bucket was 6.7 cubic meters. It easily accommodates one full size bus. Huge tracks are used to move the Bagger 293.
RH 400
Another class of excavators is hydraulic machines, a feature of which is that they use exclusively hydraulic drive. The largest hydraulic excavator is the German RH 400. It was created by the efforts of O and K. With a mass of 980 tons, it worked with an operating power of 3.5 megawatts. Bucket RH 400 holds 50 cubic meters of earth weighing a hundred tons. The cost of the car was 14,000,000 US dollars, while due to high efficiency it quickly pays for all invested funds.
The RH 400 is designed in such a way that it is able to perform its functions even in very extreme conditions. In addition, oil heating systems allow it not to stop in the cold. An excavator worked in Africa when creating a dam. Responsible for his work powerful engines Cummins-QSK 60C with a total power of 4600 horsepower and a torque of 1800 rpm. The giant's fuel tank holds 15,000 liters. The RH-400 creates a ground pressure of 26 Newtons per square centimeter.
The list of the largest excavators is crowned by Bagger 288. Work on this titan began in 78 of the last century. The machine is capable of extracting minerals from depths that other most powerful excavators are not able to work with. The price of this colossus is a little more than a hundred million US dollars.
Bagger 288 moves with the help of a caterpillar at a low speed (only 600 meters per hour). The efficiency of the machine is so great that in a day of its operation it extracts so much ore that it takes 4,000 heavy vehicles to take it all out (in reality, wagons are used). About 10,000 cubic meters of rocks are processed per hour.
Excavators are earthmoving machines that have different purposes. They can be used for digging quarries, holes for building houses, and also for mining. All mechanisms differ not only technical specifications, appearance but also in size.
The top 10 included largest excavators in the world throughout history earthmoving.
Hitachi EX8000-6 - modern hydraulic excavator from Hitachi opens the rating of large excavators. The machine was built in 2012 for coal mining.

Giant machines that impress only with their appearance… TravelAsk knows how to surprise: these are not only huge giants, they are also very complex structures. Let's talk today about the most large excavators that the world has ever seen.
German giants
We will talk about two huge machines: Bagger 288 and Bagger 293.
It is the latter that is listed in the Guinness Book of Records, but it is younger brother the first and in size, in fact, is not much different.
Bagger 288
This colossus was built in 1978 German company Krupp. The giant surpassed in size even caterpillar conveyor NASA, which is used to transport shuttles and Apollo rockets to the launch pad. The weight of the excavator is 13.5 thousand tons. Bagger was built for about five years.
Rheinbraun ordered this car. It cost them almost a hundred million dollars. However, this investment paid off fairly quickly. The fact is that the company extracts minerals, and they needed equipment that would get them from such bowels of the earth that are not subject to any other technique. They immediately dismissed the classic version of mining with bulldozers: they can reach the target for months. And this giant will cope with the task in two days.
How Bagger 288 works
The buckets of the world's largest excavator are mounted on a rotating wheel. Thanks to this, the machine is constantly digging. The machine has eighteen buckets, each with a volume of 6.6 cubic meters. To understand these dimensions, it is enough to imagine that a man under eighty meters can easily get into the bucket.
Bagger processes about ten thousand cubic meters of rock per hour. It is immediately unloaded onto moving conveyors, and from them it is loaded into wagons or placed side by side. Ordinary KAMAZ trucks will not cope with such volumes. More precisely, they will cope, but in order to take out the rock mined by an excavator in a day, 3822 KAMAZ vehicles will be required.
Giant dimensions
The dimensions of the excavator are huge: its length is two hundred and forty meters, its width is forty-six meters, and it is ninety-four meters high.
The excavator has twelve caterpillars, each of them about four meters wide. Sixteen engines make it work. We have already mentioned the weight - 13,500 thousand tons. But, despite such a mass, the pressure on the ground from the excavator is small.
One cannot cope with such a colossus: it is managed by a whole team of four people.
Do you know what the speed of this colossus is? Only six hundred meters per hour. So he may well be jealous of the turtle.
Bagger 293
This giant is now engaged in coal mining in Germany near Hamburg. Just imagine its dimensions: the excavator is 225 meters long (this is slightly less than the Bagger 288), 96 meters high (like its older brother).
The giant processes about 219 thousand tons of soil or 240 thousand cubic meters per day (as well as Bagger 288). What did he do better than his predecessor, you ask? Its weight is 14.2 thousand tons. Before its construction in 1995, the Bagger 288 was the absolute record holder.
