We watch the cars adorned big wheels. The huge radius of the disks looks impressive, even intimidating. It is obvious to everyone that there is a predator on the road. However, be aware that it can be practical. How good are large wheels, let's take a closer look.

When purchasing a new “horse”, many people think for a moment, maybe they should install disks on a car with a larger landing size. In the list of services, it is possible to install a couple of inches more radius. However, the brake system will have to be changed. For adequate operation of the brakes, it is necessary to modify the length brake pipes and hoses.

Let's dive into the chronicle

If we consider the chronicle of the change in the parameters of the wheel, two currents will be found. At first, the wheels became smaller in size, a little later the landing and outer radius actively increased. Let's dive into the historical background. The cars that appeared first had really huge wheels.

You know, on the Mercedes Simplex they attached "wheels" 910 to 90 and 1020 to 120 to rear axles. In a radius, that's practically 80 inches! The landing size was over 20 inches. This is way back in 1902.

Large wheels have a good effect on the vehicle's patency. Each car was, in theory, an SUV. This is not to drive on an asphalt highway! The roads, or rather the paths, were country roads, with various bumps and pits. The wheels used to be with thin rims. wide wheels will start producing much later. The profile height will remain at least 70 percent of the width. Until diagonal tires take the place of radials.

Wheels on such cars were, of course, made of wood. Only in the latest issues did an innovation appear - stamped steel disc. Some time has passed. Shiny spoked wheels became popular.

Half a century later… In the 1950s, cars ran on thin, narrow wheels. The diameter has become smaller. Passenger cars no longer needed to make their way along such broken paths. The Moskvich 402 car rode on wheels 5.6 by 15. The same applied to many models. The most reduced wheel radii went to cars from the 70s to the 90s. The landing diameter has become smaller - 13-14 inches. The dimension of the tire section slowly decreased to 75, and later to 65 percent.

After a while it is observed stable increase in wheel size. Tire radii have become larger and on the smallest cars - up to 30 inches. The most popular disc diameters were 16. Here you can’t say that the reason was the obvious destruction of roads, but due to the need to increase cross-country ability. Maybe it's just become fashionable?

One fashion cannot explain the focus on increasing the size. A car with large wheels looks impressive and attractive. At least it looks more like a design sketch than a typical copy. It is much more interesting to develop a beautiful disk design in such a situation. There are, however, reasonable reasons for the growth of the wheels.

You probably know about cars called "lowrider". They are famous for their lowered modified suspension. So, installing big wheels is an inexpensive and simple transformation that allows you to bring out the accent of the lowrider style.

Often elevated wheels need increased wheel arches. Especially if the wheels work together with a lowered suspension. Sometimes large wheels are given decorative rims of arches with a metallic sheen. Looks extremely impressive. At the same time, large wheels require thinner tires. Decorative frames of arches are fashionable to decorate with cool design solutions, by type: futuristic or strict form of arch bulge or airbrushing.

Is the wheel with the largest outside diameter better?

On the one hand, yes. Because the contact area between the tire and the road will increase. Even without making the tire softer, it is possible to expand the plane of contact with the road surface by reducing the curvature of the wheel itself at the point of contact. You may not feel the difference, but this does two things:

1. Improving the grip of the wheels and the track. Reduced braking distance will increase the safety of driving in general.
2. Increasing economy. You can use a tire with a lot of pressure and not be afraid of deteriorating wheel traction.

In turn, increasing the working tire pressure will allow you to more accurately control the car. Machine coordination will be better. The bending of the sidewall of the machine wheel will decrease. But that's the main problem. pneumatic tires. An increased lateral load on machine wheels leads to a curvature of the contact patch, a deterioration in the optimal tread shape. Grip deteriorates, in this situation, when part of the tire simply loses contact with the road surface.

Under the term "breaking" refers to a situation in which the sidewall of the tire loses its shape due to overload. In this case, the tire comes into contact with the side of the track, while the treadmill of the wheel is practically not put into operation. The rim is depressurized with the tire. As a result, traction with the road surface is lost almost completely.

Permeability also becomes much better. This is due to the increased length of the sealing wedge. This is the name of the zone within which the limp soil of the road does not scatter in the axles, but gains strength, bending under the wheel. Ground clearance and visibility also increases due to the large wheels.

Disadvantages of a large outer diameter wheel

Unfortunately for everyone, it is impossible to simply increase the size of the wheel to improve traction. Let's stop at consequences of an increase in diameter. First of all, now the wheels will become heavier than the usual, standard ones. The consumption of rubber and metal will also increase.

The mass of the wheel and parts of the suspension arms will increase. This mass is called "unsprung". All this makes the grip of the wheel with the track uncomfortable. In the back, the spare wheel will take up much more space, creating harmful air turbulence along the way. Big wheel is actually softer than usual, it negatively affects the handling of the car.

With shortcomings, an active struggle is quite possible.

The tire diameter continues to increase.

It is clear that the larger wheel has grip advantages, only if the side surface does not break and does not lose shape in a turn, the rigidity of the rim will help to avoid its curvature under the influence of lateral load. In other words, the negative effects of increasing the mass of the wheel, most likely, will not be able to outweigh the positive ones.

By reducing the height of the tires, we found a way out. This was the reason to make a larger landing diameter. Resistance to lateral forces has become better due to the fact that the height of the sidewall has been minimized. The rim is stiffer than rubber. An alloy wheel, in turn, has a greater rigidity than a steel one. So the total mass of the tire + disk will be slightly less.

In addition, increasing the size of the inner diameter of the tire, namely the diameter of the disc, is extremely optimal for the brake mechanism. Because of design features disc brakes are most often placed inside the wheel disc. The size of the disc, as a result, imposes restrictions on the dimensional parameters of the brake disc, as well as the caliper. The cooling of the brakes is faster and better, due to their size. In addition, it will provide a smooth deceleration, among other advantages.

Low profile tyres. Flaws…

There are no perfect technical solutions. By lowering the profile of the tire, and increasing the landing diameter, we get our own disadvantages of such a solution. Rolling stiffness and vibration await us with a decrease in the cross section of the "rubber layer". The body of the car and the suspension have a lot more bumps and bumps.

The increase in pressure of the machine wheel in operation also affects. This will make it tougher. The tire will cost more due to the increased requirements for sidewall strength and the difficulty of maintaining the shape of a wide machine tire with low beads.

New suspensions and modern shock absorbers will cope with the disadvantages of low profile rubber. However, the fact is indisputable: high profile provides the car with better comfort.

Expensive factory big wheels

Service centers offer the option of installing more rim. However, the cost of such pleasure is extremely high. Why then the price of a set of branded discs from a reseller costs less. Why is that and where is the catch?

The fact is that the service also includes adjustment of the suspension parameters, as well as the brake system. They put brake systems and shock absorbers made specifically for the wheels are heavier than usual. Putting a winter kit with wheels a couple of inches smaller on this car will not work. Smaller tires will not fit on such a caliper.

Summing up

Advantages of big wheels:

• The car will improve handling.
• Acceleration dynamics will become better, and the braking distance will become shorter on the road.
• Attractive and daring car exterior.
• By increasing the outer diameter of the tire, the permeability becomes much better.
• The brake system is replaced with one that is more powerful.
• Review from driver's seat will get much better.

The modern world is a time of incredible technologies that help create giant machines with enormous power. Mankind forces the forces of nature to work for itself: steam, water, electricity. By creating complex mechanisms, machines are capable of performing dangerous and hard work. The impressive size of each representative allowed them to enter the top 10 biggest cars in the world.

10. American Dream Limousine

The American Dream limousine is one of the largest passenger cars and the world champion in length (30.48 m). It was specially built in the 1980s. for the filming of the film "Back to the Future", "Starsky and Hutch", etc. To this day, he is in the lead in the "Guinness Records".

The car is real, 26 wheels support a large waterbed inside the cabin, a jacuzzi, a mini-pool, there is even a platform for a helicopter. The basis of the car was the "Cadillac Eldorado" of the 1970s, its outlines remained only in small details of the exterior.

For a convenient turn in the car there is a "fracture", only in this place you can turn the limousine, as in a road train. The trailer is the back of the car, it can be unhooked; in a shortened version, the car is more mobile.

The American Dream limousine has space for 2 drivers, one in the back to follow the turns. The machine does not have a certificate for public roads, so it is transported by trucks, previously divided into 2 parts. Now the limousine is under restoration, after which it will become an exhibit of the museum in New York.

The cargo An-225 or Mriya is the largest aircraft in the world, measuring 84 meters long, 88.4 meters wide and 18.1 meters high. Only he can lift up to 250 tons on board, and the take-off weight is 640 tons. An-225 can reach speeds of up to 850 km / h with a flight range of 15.4 thousand km. at an altitude of 11 thousand meters.

To land, the plane needs a runway of 2400 m. The Mriya chassis is larger than that of all other aircraft in the world. The weight of 640 tons (this is the weight of nine loaded Boeing 737s) is supported by 32 wheels.

The aircraft is operated by a crew of 7, which can accommodate another 88 passengers. The aircraft has 6 turbojet engines, each with twice the thrust of the Concorde supersonic aircraft.

8. Komatsu D575A

The Komatsu D575A bulldozer weighing three tanks (152.6 tons) continues the top ten largest machines in the world. If we compare it with a traditional conventional bulldozer, then it rakes 3 times more than its counterparts with a blade. The Komatsu D575A is 1.5 m long, 7.5 m wide and 4.9 m high. The machine is used in US coal mines and is called the "King" among bulldozers.

On the 7th place in the list of the largest machines in the world is the Liebherr T282B dump truck. The brainchild created by Liebherr is not much inferior to the record holders. This is the leader among machines in terms of carrying capacity. The dump truck is designed for heavy work in quarries. It has been specially designed to work in the difficult conditions of South Africa, Canada and Australia, able to go anywhere.

The monster is 14.5 m long, 7.4 m high, 9 m wide and weighs 232 tons. The machine can carry loads 1.5 times its own weight (up to 363 tons). In its body you can put a small house. A powerful unit under the hood hides a 20-cylinder engine with more than 3,500 hp. with., and the fuel tank holds 4,730 liters.

The Caterpillar 797B dump truck continues the ranking of the largest machines in the world. He successfully works in coal mines, in gold and copper quarries. The dimensions of the mining dump truck are impressive: height - 8 m, length - 15 m, and width - 9.5 m. Its weight is 280 tons, and its carrying capacity is up to 345 tons. This rather fast machine can reach speeds of up to 68 km / h. Huge fuel tank holds 6800 l.

BelAZ 75710 occupies the middle of the ranking of the largest vehicles in the world. This dump truck was designed to work in coal mines. Start of production - 2013, deliveries were made to the Kemerovo region. The height of such a giant truck is more than a three-story house (8.17 m), the length of the car is 20.6 m, and the width is 9.75 m. The weight of the BelAZ 75710 is 360 tons. railway wagons. Only one dump truck wheel has a weight of 8 tons, and the volume of the fuel tank is more than 4300 liters.

The noise of the engine of a giant truck is so loud that you need to wear headphones in it. The price of a miracle dump truck is also considerable - 6 million dollars.

The huge Terex 33-19 Titan dump truck was manufactured in 1974 in one copy by the well-known General Motors company in the Canadian division. It was created for hard work in mines (quarries). The three-axle cargo monster has faithfully worked for two decades in the quarries of Canada, transporting up to 350 tons of various cargoes at a time, it weighs 235 tons.

The dimensions of this machine were the largest on the planet among dump trucks: the length is 20 m, the height is 6.9 m. The maximum speed is up to 48 km/h.

Now Terex 33-19 Titan has long been on vacation (since 1992) and is an interesting attraction for thousands of visitors to one of the museums, which is located in British Columbia in Canada.

In third place among the largest machines in the world is the Zoomlion ZACB01. This is the largest truck crane not only in terms of size, but also in terms of carrying capacity. The novelty of construction equipment was produced in 2012 in China, the release of the machine is specially designed for the 20th anniversary of the Zoomlion manufacturing company.

The lifting capacity of the crane is 2000 tons, the telescopic boom is extended from 8 sections. The machine can freely move loads in any direction at a distance of 160 m. The weight of the crane is 96 tons, and the lifting capacity is 20 times greater.

The second line of the rating goes to Bagger 288 - the world's largest excavator, 240 meters long and 96 meters high. Such a monster weighs 13,000 tons, it has no equal in strength and dimensions. The rotary giant excavator extracts up to 230 tons of coal per day. In a few days he accomplishes such a volume of work that his brethren would not have coped with in six months.

At a minimum speed (0.6 km / h), in order to relieve the load on the ground, the Bagger 288 excavator is equipped with 12 tracks, each 3.8 m long. Thus, the designers reduced the pressure of the giant machine to the human foot. Therefore, the giant can safely move even through the fields without harm to the soil.

For one shift of a unique machine, 4 people are needed: a shift supervisor, 2 excavators and a belt conveyor coordinator. The control of the miracle machine is done with the help of joysticks. Ideal conditions for comfortable work have been created, inside there is a room with a kitchen and a bathroom.

But first you need to make a little clarification and explain why the emphasis here is on the rear wheels. The fact is that in powerful supercars during acceleration, due to the redistribution of weight, the main load falls on the rear wheels. And if there is a whole car under the hood, then the wider the tire, the higher the "hook" and the more efficient the transformation of this power into acceleration. This is why the rear wheels of sports cars are generally wider than the front ones.

Width 315 mm

Tires of the same width (315 mm) as those of the future Dodge Challenger SRT Demon are now worn, for example, by the Ferrari F12tdf, built in a limited edition (799 pieces) in honor of the Tour de France. It is based on the ferocious F12 Berlinetta itself. But the special version of tdf is even meaner!

It is noteworthy that for the rear-wheel drive F12tdf, Ferrari also offers winter wheels. They are narrower than summer tires, and the manufacturer allows the use of rear tires with a width of "only" 305 mm with chains!

The Italians boosted the standard atmospheric 6.2-liter V12 engine for the F12tdf from 740 to 780 hp, and the torque increased from 690 to 705 Nm. And all this traction has to be taken on rear wheels through a "robot", which had gear ratios "shortened" by 6%. After all these alterations, the F12tdf picks up 100 km / h in 2.9 seconds, accelerates to 200 km / h in 7.9 seconds, and maximum speed is equal to 340 km/h.

Width: 325 mm

Mercedes-Benz, Porsche

Didn't expect to see an SUV in this review? But this G 500 4x4² is already equipped with such rubber from the factory that you will not find it on every sports car! At Mercedes-Benz, this "super Gelendvagen" came off in full. They put portal bridges on it, bringing the clearance to 46 cm (!), "harnessed" a 422-horsepower V8 gasoline bi-turbo engine, with which acceleration to 100 km / h takes 7.4 seconds ... And so that all this crazy economy tenaciously clings to the asphalt and less sinking on the roads, supplied the "square" with 325/55 R22 tires - the largest ever put on a serial 4-wheel G-class!

For the background, wheels of the same width (albeit only at the back) are placed, for example, on the hybrid Porsche 918 Spyder, which is three-engine and, for its part, also no less crazy. The "heart" of the most-very Porsche in the company's history is a 4.6-liter naturally aspirated V8 with a return of 608 Horse power and "cut-off" at 9150 rpm. And each axle here additionally turns its own electric motor. In total, it turned out 887 hp. and 1280 Nm of thrust (this is more than the more powerful LaFerrari), acceleration to 100 km / h in 2.5 seconds and a top speed of 351 km / h. By the way, we have already managed to get the 918 Spyder too.

Width 335 mm

Another "American" in our review is the "hot" Chevrolet Corvette Z06 of the current generation. And at the back, he has seemingly solid tires with a width of 335 mm. But if you remember what kind of monster lives under the hood of the Z06, then this value no longer seems so impressive.

The current Corvette is the last to have the engine in the front. The next Corvette will be central-engined and even more powerful. Apparently, the wheels will become even wider.

And under the hood, the Z06 has a hefty 6.2-liter V8 equipped with a mechanical supercharger. It was with the help of this compressor that 650 hp was squeezed out of the engine. and 881 Nm of torque, which are capable of turning rubber into a rapidly burning "consumable" without much stress. But the upcoming version, which will be a farewell for the current generation of Corvette, will develop 750-800 "forces"! Poor tires...

Width 345 mm

Lamborghini and Koenigsegg

Another unexpected SUV in our review is the famous Lamborghini LM002, nicknamed "Rambo-Lambo", which has long passed into the category of collector's rarities. The car was born after the failure of Lamborghini in the US Army tender, which was eventually won by the equally famous Humvee. But the Italians did not throw away the developments and eventually "grew" from them a luxurious civilian LM002 with a 450-horsepower V12 from the Countach sports car. And especially for this monster, Pirelli created huge high-profile tires measuring 345/60 R17! They perfectly kept a heavy car not only on asphalt, but also on sand, which is not surprising: LM002 was made with an eye on Arab sheikhs ...

LM002 is Lamborghini's first production SUV. True, from 1986 to 1993, only 328 vehicles were produced, 140 of which were military versions for Libya and Saudi Arabia. On request, the LM002 was also equipped with a 7.2-liter V12 from a sea boat!

In contrast to the crazy SUV from Lamborghini, let's recall the no less crazy hypercar Koenigsegg One: 1 (top photo) weighing only 1.36 tons. The essence of this device is in the name One: 1, which meant a ratio of 1 hp. /1 kg of weight. Due to two turbochargers, 1360 hp were squeezed out of the 5-liter V8 in Koenigsegg. and 1371 Nm of torque. And all this - on the rear wheel drive! To "convert" this into acceleration to 100 km / h in 2.8 seconds, Michelin rear tires with a width of 345 mm were called upon. By the way, for One:1 tires, a "maximum speed" of 440 km / h was declared!

Big, beautiful off-road tires are a key component for any off-road vehicle, as the increased wheel size adds ground clearance and traction to the vehicle. Plus the big wheels look amazing. But did you know that big wheels will cost you some ? Here is more about this topic.

look Subaru test at the stand for measuring the power of the car. The authors of this decided to find out how big wheels affect the power of the Subaru CrossTrek.

As follows from the explanations of the author of the video, the test car was delivered from the factory with all-season Yokohama tires Geolander R17 225 / 60. Then, before the test on the stand, Subaru CrossTrek installed off-road tires BF Goodrich R15 235/75.

Also, off-road wheels gave the car extra weight. According to the video description, the off-road 15-inch wheels added 11.6 pounds (5.26 kg) of unsprung weight to the Subrau. That is, in fact, the weight of the machine has increased by more than 5 kg.

So let's move on to the 2018 Subaru CrossTrek dyno results. Initially, the power of the car should be 152 liters. With. with a maximum torque of 145 lb-ft (197 Nm). On the day this video was filmed, a Subaru dynamometer with stock wheels showed a maximum output of 141 hp. With. with a maximum torque of 131 lb-ft (178 Nm).

With regards to off-road 15-inch wheels, by installing them on the car and testing it at the stand, the experts found out how it affects the technical Subaru specifications. So, the test results showed that the Subaru CrossTrek on 15-inch wheels with BF Goodrich R15 235/75 tires produces only 127 hp. With. with a maximum torque of 122 lb-ft (165 Nm).

What happened? Why wheels with a smaller disc diameter, but with big size tires so affected the car? Why has Subaru's power and torque dropped so much?

It's all about rotational inertia, which fluctuates in the mass of the wheel. Indeed, according to the laws of physics, the faster an object rotates, the faster its rotational mass decreases. So, off-road wheels are heavier and 1 inch larger in outer diameter, respectively, the rotational inertia decreases, which, of course, ultimately affects the mass of the wheels. Consequently, heavier wheels inevitably result in a loss of power.

By the way, well-known video blogger Jason Fenske explained this from a scientific point of view back in 2013, detailing how wheel size affects power and maximum torque. Here is his video:

As Fenske explains, the key point is why as you increase the diameter of the wheel (even if you decrease rim By putting on off-road tires with more meat, you will most likely increase the outer diameter of the wheel) plays, and therefore this leads to slower acceleration of the car. Moreover, this happens without taking into account weight, for example, when installing off-road tires and new rims did not increase the weight of the car (although in most cases when installing off-road wheels vehicle weight tends to increase). But in our example, Subaru has become heavier by more than 5 kg. Accordingly, weight still further affects the loss of dynamic performance of the car.

You look, judging by the measurements on the dyno, the Subaru CrossTrek lost 14 hp. With. and a maximum torque of 9 lb-ft (12.2 Nm), and is also heavier by more than 5 kg. And this is only because of the increase in the outer diameter of the wheels by only 1 inch.

True, this test does not prove that such a substitution standard rubber off-road will definitely lead to the same results.

However, most likely, installation on any car instead of factory tires for the city off-road tires will inevitably lead to loss of vehicle power.

And note that we were talking about all-season tires. And how much power will the car lose if, instead of the usual city regular 17-inch tires, winter off-road tires of the same size and the same diameter are put on the Subaru? You know, there is no such information on the Internet yet. It's just that no one has yet taken measurements on the stand to answer this question. But judging by the weight winter tires for the Subaru CrossTrek, one can imagine how much the power and torque of the car will drop after the car becomes heavier by about 20 kg (due to the increase in unsprung weight). And we are not talking about fuel consumption yet. After all, we all know that the greater the weight of the car, the greater the consumption.

So if you want to equip your car with big wheels, you should know that it will inevitably lose power and strength. If you want a car with large wheels not to lose dynamic characteristics, then you then need to modify your car, improving the gearbox, engine or drive.

Nowadays, the world is absolutely crowded with cars. Especially "lucky" is to observe the residents of large cities, who stand for hours in traffic jams to get to their place of work or study. Did you know that the biggest cars in the world are so huge that they can't fit on a regular road? At the same time, they are able to do the work that is feasible for dozens, or even hundreds of small machines. We invite you to familiarize yourself with the rating of these giants.

Road trains LeTourneau

In the rules traffic A road train is a vehicle to which a trailer is attached. One. But in the history of mechanical engineering there is a case when the road train reached an impressive length of 140 m and “pulled” not one, but three trailers.

In the 50s. of the last century, the US Army had problems supplying remote military places where Railway. They turned to the domestic company LeTourneau, so that its specialists would build a super-car that could carry tons of cargo on its board.

This unique road train under the LeTourneau LCC-1 model was born in 1954. It consisted of a truck acting as a locomotive and three wagons on wheels. So that the whole structure could easily overcome many kilometers of the road, each wheel was equipped with its own electric motor. Additionally, the road train had a generator - a 600-horsepower diesel engine, which was located in the locomotive.

The pilot project pleased the military, so in 1958 they invested in a new train on wheels. The TC-497 Overland Train Mark II model consisted of a locomotive with 14 cars and reached a length of 180 m. The crew driving the road train was located in a large cabin located at a height of 9 meters.

This huge car could withstand a load of 150 tons. He could move up to 650 km. The maximum speed was 32 km / h.

Over time, the American government ran out of money to finance this project, and the huge machines turned into museum pieces. The first model was presented for inspection at a museum in Alaska. The second is in the Arizona Museum.

To work with rocks, people came up with very large cars. They are capable of lifting from the bowels of the earth or transporting hundreds of tons of cargo, and they themselves weigh quite a lot to perform their tasks.

One of these super-cars is the T282B model from the German company Liebherr. This is a dump truck with an engine power of 3650 hp, weighing 232 tons. The dimensions of the car are also decent: its height reaches almost 7.5 m, the width is 9 m, and the length is 14.5 m. filling tank fits 4730 liters of fuel.

The Liebherr T282B dump truck is called the vehicle with the largest payload in the world. At a time, he is able to transport about 363 tons of rock.

In the photo you can see that this monster dump truck has huge wheels. They are made specifically for this model for several months. An interesting fact is that they are always in short supply - the Liebherr T282B "wears out" them faster than a new set is produced.

This supercar is slightly behind the previous participant in our rating in terms of carrying capacity - BelAZ transports 320 tons of cargo in one run. But at the same time, it is also considered one of the most gigantic machines in the whole world.

The weight of the famous BelAZ is prohibitive - about 560 tons. It reaches 15 m in length. The fuel tank can be filled with 4375 liters of fuel.

The dump truck has extremely powerful engine- turbodiesel with 18 cylinders Cummins QSK78-C. Its volume is 77 liters, while the maximum power reaches 3.5 thousand hp.

The motor is so powerful that it is very noisy. Therefore, BelAZ drivers are required to work only in specially designed headphones that protect their hearing and allow them to keep in touch with each other.

Terex 33-19 "Titan" until recently was the most big car in the world, but technical progress does not stand still and there are more overall and more powerful cars. Today, this miracle of technology is an open-air exhibit in one of the cities of Canada.

During active work, Titan transported 350 tons of rock at a time.

The length of the dump truck reaches 20 m, the height is 7 m. If the unloading tank is extended, the height of the vehicle increases to 17 m.

The Japanese Komatsu car is the largest bulldozer on our planet. It is capable of moving soil volumes that are several times greater than the capabilities of standard bulldozers.

The weight of the car is as much as 153 tons, and the capacity of the fuel tank of this heavyweight record holder reaches 2100 liters. It has three speeds for movement in both directions.

Bulldozer dimensions: length - almost 12 m, height - 5 m, width - about 7 m. The Komatsu D575A-3 SD motor has a power of 1150 hp. This turbodiesel is equipped with 12 cylinders.

Another large dump truck refers to machines for working in quarries and mines. It transports coal, ore and other minerals. First put into operation in 2002.

Its length reaches 15 m, and its height is 8 m. The Caterpillar 797B weighs as much as 280 tons. A career auto monster can carry one and a half times more cargo than it weighs (345 tons). Its fuel tank is considered one of the most capacious - up to 6800 liters.

A distinctive feature of this dump truck from other representatives of our rating is its speed. He can move with a record speed of 68 km / h.

New modification of the model from Caterpillar- 797F - was introduced to the public in 2008. This bulldozer is considered the most massive such vehicle for quarry work - it is popular in the States and in the countries of the Western Hemisphere. Carries 363 tons of cargo at a time, weighs the same as the previous model. The increase in carrying capacity made it possible to increase the efficiency of its use in work.

Can one the only car provide electricity to the whole city? Yes, it can when it comes to the biggest Goliath excavator. It was made in a single copy to work in a coal mine in Canada.

The coal seam in the quarry is located at a depth of 20 m, and the excavator itself must get to the rock and extract it. He easily copes with the task, taking out 48 thousand tons of soil from the bowels every day. Therefore, its dimensions are impressive - 65 m in height, 122 m in length of the boom and 250 tons of weight of the bucket itself.
