The world's largest tap: where is it used?

Large-scale human creations are always admired. People have learned to build high-rise buildings, extract fossils from the earth's interior and accumulate atomic energy. But how exactly are global structures built? What controls heavy beams and arches? And it concerns real heroes - cranes. Let's consider, what is the biggest crane in the world exists for today and how it is used.

Leader among truck cranes

Undoubtedly, the most impressive and powerful truck crane is the German creation LiebherrLTM-11200-9.1, in the common people called "Mammoth". In 2007, the largest crane of this type was listed in the Guinness Book of Records.

The main power of the "Mammoth" is hidden in its arrow, which has eight telescopic sections. These are the largest length indicators in the world that exist today. So that the machine can move and stand firm, it has nine major axles, which are controlled by eighteen wheels.

The cargo with which the crane is most often operated has a weight of 363 tons. The permissible capacity for additional installation of special units is 1200 tons. The largest wheeled crane is designed to work at a height of 180 meters, but this reduces its capabilities. The maximum load, raised to such a height with the maximum extended arrow, is 1.3 tons.

Technical characteristics of the world's largest crane

Imagine a huge machine with an incredible arrow, the length of which exceeds all conceivable and unimaginable parameters. How to retain such power? How to make sure that the biggest Liebher crane still lifts such loads? This requires powerful supports.

Under the main boom is a large system that performs a counterweight. It is a base weighing 22 tons, on which ten plates of another 10 tons each are installed.

The crane works thanks to a 6-cylinder 240 kW engine. The average speed when driving is 12 km per hour. Despite its powerful capabilities, the crane weighs only 220 tons.

Using the Liebher crane

As reported by the Germans, most often order this machine for large-scale construction in Europe and the Middle East. The biggest problem is transportation. Even on land, at least 20 trucks are required to move all the components. The installation of the crane takes from 8 to 10 hours. In Europe, the largest wheeled crane is widely used for the installation of wind turbines.

The mobile crane can often be found on construction sites of solar batteries and high-rise buildings, television towers and bridges. Controlled by a whole group of operators who monitor the monitors for the load and for general indicators, excluding even the slightest error or error.

The world's largest crane Liebher can be used wherever the maximum load capacity is required. Its great advantage is that, unlike its giant competitors, it is very mobile. Often the unit is used in the military sphere to mount experimental facilities.

Crawler Giant

Residents of the Celestial do not cease to amaze. Chinese manufacturers claim that their LR13000 is the largest crawler crane that can move independently. Its maximum capacity is 3,000 tons, although in 2011 the world saw the development of the same Chinese in the construction of a new crane with a lifting capacity of 3,600 tons. The only nuance is that such a huge load can be raised only by 12 meters.

In fact, the height of work is much greater. Such cranes are widely used in the construction of oil and chemical plants. Also, the construction of dangerous parts of nuclear power plants is not without them.

The most interesting is that during its operation, the LR13000 does not use a counterweight. Its design resembles a deployed boom, which provides stability. Powerful cables installed on both sides can provide a lifting capacity of up to 62 tons each. And the hook raises the equipment to the height of a 74-storey building.

"Titan" of our time

Have you ever wondered what is the largest lifting capacity of a crane? It's very hard to imagine, but the highest weight that a car can raise is 20,000 tons. Twenty thousand tons! This is 660 cars or 21,000 Lada cars!

It is difficult to imagine even the place where the crane can be used. His construction is engaged in a Chinese firm, and the design itself is stationary, that is, does not involve transportation. The purpose of its existence is the erection of oil wells in the depths of the sea. For this purpose, a crane is specially erected on the provided platforms, which are then simply removed. And after that, "Teysun" (this is the name of the modern "Titan") starts to mount a borehole.

To date, the most famous specimen is working in Shandong Province. It took 10 years to erect it, but already at its opening the crane set a record - 20133 tons at a height of 30 meters above the water level.

Huge tower crane

German company Wolffkran has created the largest tower crane in the world. His model is identified as 1250V. The maximum crane can lift 60 tons, but not on a fully extended boom. With this load, its capabilities are reduced to 11 tons, because the maximum boom radius reaches 80 meters.

The world's largest crane immediately after the presentation of the public went to its first job - to build a hydroelectric power plant in Germany. Today it can often be found in the process of working on objects on all continents of the world.

The price of such a tap is simply transcendental. Anyone, even the most high-budget project, can hardly afford to buy and transport a high-altitude crane. Therefore, Germans are willing to draw up a lease. This increases the popularity of the unit and makes it more affordable for construction sites in the world.

The largest floating crane

The immensity of the sea depths forces the engineers to design all the big and big technological innovations. And in this case, again leads China. Their largest floating crane is known as the DLV4000. From the depths of the sea, it is capable of lifting a cargo weighing up to 4,400 tons.

Where can there be such loads, you ask? Of course, in places of oil and gas production. It is more rational to drop the DLV4000 hook once than to do it a hundred times, but with a smaller machine. In addition, the world's largest crane used at sea is able to perform its work in hard-to-reach places, on dangerous shelves or in cold weather conditions.

It remains only to imagine the size of this giant. The length exceeds 174 meters and the width is 48 meters. It feeds on 7 diesel engines, which have their own power plant. Continuous tap can work for 60 days, but such overheating can not be allowed. Boat means can lift a submarine, as they say, with one finger, and not even blink.
