Large construction equipment has always been admired by outsiders for its size and power. Excavators undoubtedly belong to the class of such machines, the dimensions of which are sometimes comparable to multi-storey buildings. Yes, the most big excavator in the world - Bagger 293 - with a mass of 14200 tons reaches a height of 96 m, which is equivalent to a 30-story building.
Of course, such a “monster” is one of a kind, but there are other models that, thanks to their amazing technical characteristics, have earned a place in this rating.
10. Hitachi EX5600-6 - weight 537 tons. The release of the first model of the Hitachi EX5600-6 excavator occurred relatively recently - in 2012. It is equipped with two diesel engines total power 3000 l. With. and a capacious bucket with a volume of 34 m³, which is able to rise to a height of 19.7 m and descend to a depth of 8.8 m. Therefore, this machine is actively used for mining rock in quarries.
Due to its ability to create serious ground pressure (236 kPa), Hitachi EX5600-6 is often used to develop deposits of relatively hard rocks, such as coal.
Despite the size and complexity of the design, one person is enough to control the excavator. The Hitachi EX5600-6 cab is equipped with advanced controls that greatly simplify the operator's work.
9. Caterpillar 6060 - 570 tons. Caterpillar 6060 is one of the most popular hydraulic excavators career type. The bucket with a volume of 34 m³ and a load capacity of 61 tons is capable of loading a mining truck in 4 passes. This reduces cycle times and improves quarry productivity.
The model is equipped with two 12-cylinder diesel engines with a capacity of 1500 hp each. With. every. The volume of the fuel tank is 13,000 liters, which makes it possible to work for a day without refueling. The movement and maneuverability of the Caterpillar 6060 is provided by a modern track mechanism, which is equipped with an auto-tensioning system for the tracks, taking into account operating conditions. The operator's cabin is located at a height of 8 m, providing sufficient overview for bucket control.
8. Liebherr R 996 B - 672 t. For many residents of our country, Liebherr is primarily associated with refrigeration equipment premium. However, refrigerators are not the main direction of the German brand. It is known worldwide as a leading manufacturer construction equipment, including large excavators.
The R 996 B is designed for the toughest jobs. Optimum distribution of mechanical loads, as well as great effort for cutting and tearing off the soil provide a relatively easy penetration of the bucket into the developed material. Efficient work assisted by a 3000 hp engine. With. and a bucket with a volume of 36 m³.
The R 996 B has a modular design that makes it easy to transport. All elements, the total weight of which is almost 700 tons, are brought to the place of operation on low-bed trailers, after which the machine is assembled like a huge designer.
7. Komatsu PC8000-6 - 722 tons. The PC8000-6 is considered to be the most productive model among the hydraulic mining excavators produced by the Japanese Komatsu engineering company. The power of the diesel drive is 4000 liters. s., which, together with a large bucket with a capacity of 42 m³, provides intensive loading mining trucks.
Along with high performance distinctive feature PC8000-6 is maneuverability. The track design allows for smooth movement within the workspace and stability while loading heavy rock. However, for objective reasons, this excavator cannot boast of the speed of movement. Large dimensions and weight limit the maximum performance to 2.4 km / h.
6. Liebherr R 9800 - 810 t. The R 9800 is Liebherr's largest excavator. It is able to function in any field conditions, effectively performing various tasks of the mining industry. A huge bucket with a volume of 42 m³ makes it possible to load 200-ton dump trucks in 3 cycles, making this model one of the most productive among machines of this class.
Two 16-cylinder engines have a total power of 4000 hp. With. and for full-fledged work require 20,000 liters diesel fuel per day. Such "gluttony" justifies itself, given the power and size of the machine. And if we take into account that the R 9800 consumes only 15% more fuel than similar Liebherr models with dimensions smaller by a third, then the consumption can be considered quite economical.
5. Hitachi EX8000-6 - 837 t. Hitachi EX8000-6 belongs to the "young" excavators, as it was released in 2012. A year later, one of the Australian mining companies successfully tested it for coal mining. Machine power 3880 l. With. and a bucket volume of 40 m³ allow you to carry 75 tons of cargo at a time.
Manufacturers EX8000-6 Special attention paid attention to the reliability and efficiency of this model. The excavator can work around the clock in any field conditions - its working life is 90,000 hours. Automatic system control idle move contributes to fuel economy, as well as reduces noise levels, which creates more comfortable conditions for the work of the operator and maintenance personnel.
4. Caterpillar 6090 FS - 980 tons. Thanks to its impressive dimensions, the hydraulic excavator Caterpillar The 6090 FS is considered an excellent alternative to rope shovels. The full filling of the body of the ultra-class dump truck is carried out in 3 cycles, and average speed material loading reaches 9000 t/h.
The rated net power of the machine is 4500 hp. with., which is achieved due to the consonant work of two 16-cylinder diesel engines. The front shovel work bucket has a capacity of 52 m³ and a maximum vertical reach of 20.2 m. Like other Caterpillar crawler excavators, the 6090 FS is equipped with automatic belt tension control, which not only optimizes the machine's travel according to specific operating conditions, but also prolongs the service life of the caterpillar.
3. Caterpillar 7495 HF - 1435 tons. The Caterpillar 7495 HF rope shovel has a payload capacity of 109 tons, which is not last turn associated with the capacity of the bucket - 67 m³. Such a machine is designed for a full load of ultra-class dump trucks in 3 runs. A first for excavators of this size Caterpillar used an energy recovery system that is activated during the turn and lowering of the bucket, saving up to 50% of electrical energy.
Despite the intimidating appearance of the machine, the manufacturer great attention devoted to the comfort of the staff. An automatic climate control system, effective noise and vibration isolation, five cameras for viewing the working space and a comfortable seat help reduce operator fatigue and more productively perform the tasks assigned to the excavator.
2. Caterpillar 8750 Dragline - 7500 tons. The flagship model in the line of draglines is without a doubt the Caterpillar 8750. This is evidenced by the technical characteristics of the machine, which are an order of magnitude higher than those of similar models. Bucket volume - 116 m³, boom length - 132.5 m, nominal load weight - 345 tons, distance from the base to the head block - 90 m.
Such equipment is considered an indispensable resource throughout the development of the mine. To reduce maintenance intervals and extend the life of your excavator, every component is built with reliability and durability in mind. Therefore, the 8750 dragline can operate continuously in both the Australian heat and the Canadian frost.
1. Bagger 293 - 14200 t. The weight and size record among all excavators belongs to the Bagger 293. In addition, it is also the largest land self-propelled machine in the world, listed in the Guinness Book of Records. Tall, like a skyscraper, and powerful, like 7 Formula 1 cars, it is capable of digging a foundation pit up to 10 m deep and an area the size of a football field in just a day.
The special design of the working mechanism allows you to develop a quarry day after day. Therefore, as a rule, several brigades, replacing each other, work on it. The Bagger 293 has a simple principle of operation: thanks to a rotary wheel with 20 buckets (15 m³ each), it removes rock, which is transferred along a conveyor belt to the dump truck loading site.
The only copy of this model was developed by Takraf. Now he works at a coal mine located near the German city of Hambach. If necessary, Bagger 293 will be able to move from one quarry to another on its own, as it moves with the help of tracks. Although, given the speed of the excavator, which does not exceed 0.6 km / h, such a move is likely to take several days or even weeks.
“The monster is oblo, huge, hawkful and barking,” the epigraph of Radishchev’s “Journey from St. Petersburg to Moscow” fits perfectly with the giant self-propelled mechanism, whose movement “without taking apart the roads” gathered crowds of onlookers near the German city of Jülich (North Rhine-Westphalia) . Then, in February 2001, a seemingly ordinary event - moving an excavator from one quarry to another - hit the front pages of newspapers. And no wonder, because the main character himself is Bagger-288, built German company Thyssen Krupp Fordertehnik in 1978, and listed in the Guinness Book of Records, is still the largest excavator in the world and today continues to work in a coal mine, where it got under its own power.
Not for the record
Can you imagine how a structure as high as a 35-storey building and almost a quarter of a kilometer long passes by you?! And German engineers, when it was necessary to move Bagger 22 kilometers from one quarry to another, decided to abandon the traditional scheme - transporting the giant in parts. And of course, not in order to get into the Guinness Book of Records, but for purely pragmatic reasons. Disassembly huge machine and its subsequent assembly in a new place would require much more effort and financial costs. It turned out to be much cheaper and faster on its own. Despite the fact that the speed of the "Bagger" is only 1 kilometer per hour or 10 meters per minute. But, in my opinion, this is quite brisk for a "colossus" weighing 13.5 thousand tons, which moves on 12 tracks. The width of each is 3.8 meters, so that the pressure on the ground reaches only 1.7 kilograms per square centimeter. And therefore, the “gait” of the “Bagger” fully withstands the usual field.
"Baggers" are different
Actually Bagger, translated from German, this is “excavator”. As you know, they are different - by type, purpose, weight, bucket capacity. Overburden excavators are used to extract open way get to the seams, for example, coal. And if the excavator itself directly draws minerals, it is called mining. Only a machine with an ordinary bucket must be able to unload the mined rock nearby or immediately onto transport, since the cycle of a traditional excavator from babies to giants is the same: scooped up - lifted - turned the boom - poured out. And it is necessary to have a place where. For a bucket wheel excavator, this is not a problem. After all, its buckets, mounted on a continuously rotating rotor, scoop up the rock in turn, which immediately spills onto the conveyor belt passing through the entire boom of the machine. The boom, in turn, can move very slowly up and down to get to the desired layer of the mined rock. And also to the left - to the right during the production itself. From the first conveyor - the rock enters the second, located in the "tail" of the rotary excavator - this is its unloading conveyor. Usually, when mining, waste rock is not taken out, but dumped next to the quarry, for which another machine is docked to the excavator - a spreader. Additional "options" give the huge mechanism an even more fantastic look: if necessary, special reloaders, main conveyors and other auxiliary equipment can be attached to the rotary "monster". In a word, career bucket wheel excavator- initially an impressive device, but Bagger-288 is able to surprise even sophisticated professionals with its scale. The length of the "288th" is 240 meters, the height is 96, the width is 46 meters. The rotor, with which Bagger cuts the coal seam, has a diameter of an eight-story building - 21.6 meters. True, the buckets installed on it are relatively “modest” in volume - 6.6 cubic meters, but on the other hand, it has 18 of them. During the day, the Bagger rotor shovels 240 thousand cubic meters of rock. This is enough to fill the bowl of a football stadium to the height of a 10-story building. But again, all this is not a record for, but for the sake of achieving high productivity in field development and maximum economic efficiency. According to German experts, the use of such giants justifies itself: in Germany, three big quarries About 100 million tons of brown coal are mined annually in Hambach, Inden and Harzweiler.
A giant depends on... sockets
Yes, yes, our protagonist Bagger-288 is constantly powered by electricity from a conventional industrial power grid, like some kind of milling machine. That's just it consumes electricity, like a small city. Still, after all, in order to move the colossus from its place and ensure the performance of all its mechanisms, electric motors with a total capacity of tens of megawatts are used. It is they who drive the tracks, the rotor, and other units of the Bagger. The excavator draws energy from a long cable of large cross section. A reel with this cable is mounted at the back of the machine, its length is one kilometer. So during the 22-kilometer marathon, the excavator cable had to be connected to various parts of the industrial network.
The crew of the combat vehicle
It could be assumed that to control such a land "dreadnought" and the team required almost ship, but the crew of the Bagger-288 - like in a tank - only four people. These are two successive excavators, operator belt conveyors, supplying coal from the rotor to the place of loading, and the head of the detachment, let's say in Russian - the shift leader. There are three shifts in total, so the "monster" bites into the ground around the clock. During operation, the crew is completely autonomous and does not interrupt production: so that they do not have to “descend from heaven”, for example, for lunch and other everyday needs, a wardroom with a toilet, a kitchen and a large supply of water is arranged in a skyscraper on caterpillars. In terms of physical effort, the work of an excavator on the Bagger is reminiscent of computer game: he controls the machine with the help of joysticks - both the rotor and the movement of the entire giant unit. It can be assumed that in terms of electronic stuffing the colossus of the 1978 edition was undergoing modernization, in any case, the navigation and video surveillance systems, which, of course, were updated, help the crew in their work. The excavator driver sits in a small booth, located not far from the rotor, right on the giant “arm” of the Bagger, where he is provided with maximum view. Its work is responsible and requires constant attention: it is necessary to ensure that the buckets are optimally filled, the walls of the cut do not collapse and are even, so that the rotor is not damaged by foreign inclusions, for example, hard rocks that are found in the layers. In a word, there are enough worries. But the shifter also has no time to cool off at this time: his duty is to periodically bypass the car, monitor the condition and operation of the mechanisms, if necessary, correct or clean something. The team leader acts as a strategist of the "battle for coal", coordinating the work of the entire brigade. And he just sometimes has to go down to pave the way for the "monster" when the excavator moves from one section of the quarry to another. But these usual "rolls" are nothing compared to the raid that fell on the excavators of the "Bagger" seven years ago.
Day and night for three weeks...
Again comparisons come to mind from national history . By order of Peter the Great, two frigates were secretly dragged overland to the Baltic Sea, when the reformer tsar decided to cut a window to Europe. For this, hundreds of peasants and soldiers cut clearings through the forests, paved the road, and dragged ships along the logs to the water. But what else can be imagined in the expanses of Russia of the 18th century is difficult to imagine in the neat and well-equipped Germany of the 21st century. After all, the steel monster Bagger-288 was not driving along the autobahn on 12 tracks! Having completed his work in the Hambach quarry, he was to start mining at the Garzweiler quarry. For the car, the shortest possible path was laid. Where it was necessary, sections of the route were sown with grass in advance so that the soil during rains would not be oversaturated with moisture and retain its bearing capacity. In a number of places, sand mounds were made. So, in order not to damage the roads and the railway line, they poured a pillow of sand and crushed stone a meter high. At the same time, note that traffic was stopped for only half a day: they quickly made an embankment and immediately removed it after the passage of a super excavator. The rivers encountered on the way also had to be covered with stones for forcing. Since the "Bagger" could not pass under the power lines in any way, they were dismantled and immediately put back as soon as the colossus passed through the line. Consumers of electricity, as a rule, did not experience any inconvenience: suppliers sent it through alternative networks. The Bugger's journey continued into the night, and from the side it looked in places like an episode from a Hollywood blockbuster. Moreover, two rotary excavators set off from quarry to quarry at once, but the second machine was both smaller and one and a half times lighter than our “hero”, so it was the Bagger-288 that caused an unprecedented stir. It is significant that the organizers of the excavator raid covered his tracks literally a day after the cars passed. Carefully, with German pedantry, the prepared special operation ended successfully: in three weeks, the steel colossus covered 22 kilometers and was able to immediately start mining in a new place. You can see the work of the largest "coal miner" in the world today. Experts are confident that with proper maintenance and repair, and if there is no force majeure, the Bagger-288 is quite capable of producing coal until its 100th anniversary. Moreover, he himself is now not just a unique and highly efficient means of production, but also a real tourist attraction, which can be seen from afar.
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 includes the largest excavators in the world in history earthmoving.

During this cycle, the colossus was able to immediately fill 3 huge wagons. The weight of the car is about 900 tons, and the power of its engine is 4400 horsepower. The length of the Big Brutus caterpillars exceeds ten meters. Currently, this one-of-a-kind copy is kept in the American Museum of the City of West Mineral.
Biggest Excavator #1: Bagger 288
Bagger 288 completes the ranking of the largest excavators in the world. It was built by Krupp in 1978. The customer for the machine was the mining company Rheinbraun, which needed a machine that could work at very great depths. IN end result the cost of the car resulted in the company 100 million US dollars. An excavator extracts such a quantity of rock per day that it would take about 4 thousand KAMAZ trucks to export it.
The Bagger 288 is equipped with 18 buckets, each with a volume of about 7 cubic meters and a height of about 2 meters. It can process about 10 thousand cubic meters of mined rock every hour. The height of the giant is almost equal to 100 meters, and the length exceeds 200 meters. The weight of the whole structure is more than 13 thousand tons. At the same time, a team of four people is working on the Bagger 288. The speed of movement of the colossus is only half a kilometer per hour.
Excavator - common name For earthmoving machines which are equipped with a bucket. There are several dozen modifications of these mechanized devices.
They differ from each other in the way they work (universal construction, mine, trench, single-bucket), in the type of undercarriage used (walking, caterpillar, wheeled, etc.), in purpose, in design and, of course, in size.
Wheel excavator example −
Applied excavators in construction (including road construction), in quarries, in mine workings. A feature of earth-moving machines of this type is that the bucket (working body) moves independently of the chassis.
In addition to excavators, dump trucks also work in quarries, for example, the largest mining dump truck -
The inventor of the excavator is considered to be Leonardo da Vinci, who created general drawing And circuit diagram machine similar to a modern dragline excavator. The first working excavator was developed by Smith Otis, an American mechanic, in the mid-1930s.
An example of a modern backhoe loader is.
The largest excavators
Rotary
The largest bucket wheel excavator in the world(until 1995), used in the coal industry - Bagger 288 (Germany). Its length is 240 m, width - 46, and the height of this giant - 96 meters. Weight - 13,500,000 kg. The excavator rotor has a diameter of 22 meters and makes 48 revolutions per minute. you can see it in the photo above.
The number of buckets is 18, the volume of each of them is 6.6 cubic meters. meters. This unit is equipped with 16 electric motors with a total capacity of 560 kW. For work, he needs as much energy as would be enough for the needs of a medium-sized village - 16.5 megawatts. In 24 hours, he extracts about 240,000 cubic meters of coal.
Bagger is served by 4 people. There is a kitchen and bathroom on board. Bagger 288- crawler excavator, its speed is not more than 600 m/h. The caterpillars have twelve supports, which allows you not to push the ground too much when moving. The famous company Krupp created this colossus.

Despite the fact that nanotechnology is actively developing, the creation of miniature earth-moving machines is unlikely to be carried out in the near future. Therefore, it is quite possible that there will be an excavator that is larger than the existing ones.
On our site you will find a description of not only giant excavators. Familiarize yourself with tracked and wheeled excavators Hyundai.
All excavators that compete in our ranking for the title of the largest in the world can be divided into two groups. In fact, these are two different weight categories, each of which has its own champion. Like in boxing.
So the first group hydraulic excavators(or excavators with hydraulic drive). By analogy with boxing, this is a small or medium weight. Are applied to loading of the blown-up rock.
Fourth place - the German giant Demag H740 OS: 
It already weighs 744 tons, but the bucket volume and power are almost the same as those of the Japanese counterpart.
Third place - Liebherr R9800 (Switzerland):
The mass of the machine is 800 tons, the volume of the bucket is 42 cubic meters. meters, but the power is less than 3900 "horses". This is understandable, the more modern the excavator, the easier it is to cope with its own weight due to technology.
Second place - Hitachi EX8000-6 (Japan):
Weight - 811 tons! Meanwhile, the score between Asia and Europe is still 2:2. There are already two Japanese excavators in the top five, one German and one Swiss. Who will get the first place?
Meet our winner - RH400 from American Terex:
It would seem that the dispute between Europe and Asia remained open due to the intervention of the American? However, it is not. Despite the fact that Terex is an American company, the Germans from O&K assembled the excavator. So victory for Europe! By the way, under this brand are produced.
With a weight of more than 1000 tons ( absolute record), the excavator has a bucket of 45 cubic meters. meters and a load capacity of 95 tons. For an hour of work, this giant is able to dig and load about 10 thousand tons of rock!

Well, now let's turn our eyes to heavy weight - mining excavators. A quarry excavator, unlike a hydraulic one, which, by the way, also works in a quarry, extracts the rock itself. Third place - mining excavator Big Muskie, designed in 1969 by the American company Bucyrus Erie to work in a coal mine in Ohio:
This excavator is walking. Unlike, its principle of movement is different. The excavator "sits" on the base plate, then rises on special hydraulic supports, and the base plate moves forward. Further, the plate is lowered and the supports are already moving forward. The step process is then repeated. The length of the excavator is almost 150 meters (one and a half football fields), and the volume of the bucket is 168 cubic meters. meters:
In 1999 after 30 years continuous work excavator resource has been exhausted. It was dismantled, and its famous ladle was placed in a museum in Ohio. Second place - Bagger 288 from the largest German industrial concern Krupp:
