The rapid development of science, industry and mechanical engineering allows you to quickly and reliably build industrial facilities and residential buildings.
During construction, it becomes necessary to raise to a height or move steel and concrete structures, tanks and reservoirs, as well as blocks of equipment and special equipment.
Only a few companies can produce machines capable of handling loads weighing more than 1000 tons.This task is taken on by modern - the most large truck cranes in the world. Let's analyze several models of truck cranes - champions, by the way, among them there are 3 manufacturers from the People's Republic of China, and one representative from Germany and the USA each.
Rating of the largest truck cranes in the world
Truck cranes are among the. On the 5th place is the machine of the American company Terex-Demag - model AC 1000. It is able to work in harsh climates and move on bad roads.
Fifth place - Terex-Demag truck crane (model AC 1000)
The crane works with a load weighing up to 1000 tons, to a height of 163 meters, the length of the telescopic boom is 100 meters. The crane boom itself consists of 9 sections, weighs 22 tons, and is transported on a special vehicle. To bring the crane in working condition, he needs another crane with a lifting capacity of 30 tons, able to assemble the entire machine piece by piece.
The main task of this machine is to ensure the operation of wind turbines and the installation of wind farms. When the crane moves along the highways, the loads on the axles do not exceed 12 tons, and this does not destroy the roads. There is also more special machine, which transports the equipment necessary for the crane - outriggers, hook block, counterweights.
Fourth place - SANY truck crane (model SAC 12000)
On the 4th place is the car of the Chinese company SANY model SAC12000. This truck crane quickly gets to the most difficult terrain. Weight Limit cargo 1200 tons.
This model has systems - fuel control, safety management, power distribution and chassis control.
The truck crane can operate in 15 modes, equipped with 4 supports, a superstructure and 2 winches. The telescopic boom consists of 4 sections and extends to a height of 102 meters.
Third place - Liebherr truck crane (model LTM 11200-9.1)
car in 3rd place German company Liebherr model LTM 11200-9.1. This machine works with loads weighing 1200 tons, has a telescopic antenna consisting of eight sections.
To work with special loads, a mandatory installation of a counterweight is provided, the weight of which is 200 tons. The crew of the machine consists of five people: an engineer, two operators and two drivers. The crane has two diesel engines, one 6-cylinder for the operation of the crane itself - with a capacity of 367 Horse power. And the other 8-cylinder is designed to move the chassis, has a capacity of 680 horsepower.
The axial piston hydraulic motor acts as the lifting mechanism of the telescopic boom of the crane. The maximum boom angle is 86 degrees.
Second place - XCMG truck crane (model XCA5000)
Such a crane can lift and carry various loads weighing 1600 tons.
In 2nd place is the car of the Chinese company XCMG model XCA5000. This crane has a lifting capacity of more than 1600 tons, the machine can move sideways and has a hydraulic servo steering. Areas of application are the construction of nuclear and maintenance of wind power plants.
First place - Zoomlion truck crane (model ZACB01)
In 1st place is the car of the Chinese company Zoomlion model ZACB01, which is capable of lifting a load of 2000 tons. The mass of this machine is 96 tons. The telescopic boom consists of eight sections and is 106 meters long. The Zoomlion truck crane (model ZACB01) was created on a 12-axle all-wheel drive chassis (24x24, QAY 2000). The manufacturer equipped the autocan with 4 engines different power(150, 260, 430 and 650 hp).
Such giant car will work in the construction and installation of chemical and metallurgical enterprises. The release of the novelty, recognized as the most lifting and high-altitude truck crane in the world, was timed to coincide with the 20th anniversary of the formation of Zoomlion.
Summarizing
IN this review of the five most powerful truck cranes, three are represented by companies from the People's Republic of China. In 5 years, Chinese firms will take a leading position in many segments of the world market, which suggests that we need to take a closer look at the products of Chinese industry and, in matters of import substitution, focus not on the West, but on the East (China).
Large-scale human creations are always amazing. People have learned to build, extract minerals from the bowels of the earth and accumulate atomic energy. But how exactly are global structures built? What governs heavy beams and vaults? And it concerns real heroes - cranes. Consider what is the largest crane in the world 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, commonly referred to as the "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. In order for the colossus to move and stand stably, it has nine main axles, which are controlled by eighteen wheels.
The load with which the crane has to work most often has a weight of 363 tons. Permissible load capacity at additional installation special units- 1200 tons. The largest wheeled crane is designed for 180 meters, but its capabilities are reduced. Max load, raised to such a height with the arrow extended to the maximum, is 1.3 tons.
Technical characteristics of the world's largest crane
Just imagine a huge colossus with an incredible arrow, the length of which exceeds all conceivable and unimaginable parameters. How to keep such power? How to make the most big crane Liebherr still lifted such loads? This requires strong support.
Located under the main boom big system, which performs a counterbalance. It is a base weighing 22 tons, on which ten plates of another 10 tons each are installed.
The crane works thanks to the 6-cylinder engine with a power of 240 kW. average speed when driving - 12 km per hour. Despite its powerful capabilities, the crane itself only weighs 220 tons.
Using the Liebherr Crane
According to the Germans, most often they order this colossus for large-scale construction in Europe and the Middle East. The most a big problem is transportation. Even overland, it takes at least 20 trucks 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 truck crane can often be found on construction sites of solar batteries and high-rise buildings, TV towers and bridges. The colossus is controlled by a whole group of operators who monitor the load and general indicators on monitors, excluding even slightest mistake or error.
The world's largest Liebherr crane can be used wherever required maximum load capacity. Its big advantage is that, unlike its giant competitors, it is very mobile. The unit is often used in military sphere for mounting experimental objects.
caterpillar giant
The people of China never cease to amaze. Chinese manufacturers claim that their LR13000 is the largest crawler crane who can move independently. Its maximum capacity is 3000 tons, although in 2011 the developments of the same Chinese were presented to the world in the construction of a new crane with a lifting capacity of 3600 tons. The only caveat is that such a huge load can only be lifted by 12 meters.
In fact, the height of the 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 complete without them.
The most interesting thing is that the LR13000 does not use a counterweight during its operation. Its design resembles a deployed arrow, which ensures stability. Powerful cables installed on both sides can provide a lifting capacity of up to 62 tons each. And the hook lifts the equipment to the height of a 74-story building.
"Titan" of our time
Ever wondered which one is the biggest? It's very hard to imagine, but the highest weight a car can lift is 20,000 tons. Twenty thousand tons! This is 660 wagons or 21,000 Lada cars!
It is difficult to imagine even the place where a crane can be used. A Chinese company is engaged in its construction, and the structure itself is motionless, that is, it does not involve transportation. The purpose of its existence is the construction of oil wells in the depths of the sea. For this, a crane is specially erected on the provided platforms, which are then simply removed. And after that, "Teysun" (that's the name of the modern "Titan") begins to mount the borehole.
To date, the most famous specimen is working in Shandong province. It took 10 years to build it, but already at its opening, the crane set a record - 20,133 tons at a height of 30 meters above the water level.
Huge tower crane
The 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 such a 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 to the public, went to his first job - to build a hydroelectric power station in Germany. Today, it can often be found in the process of working at facilities on all continents of the world.
The price of such a crane is simply sky-high. Any, even the most high-budget project, is unlikely to be able to afford to buy and transport a high-altitude crane. Therefore, the Germans are willing to arrange leasing. This increases the popularity of the unit and makes it more and more accessible to construction sites around the world.
largest floating crane
The immensity of the sea depths forces engineers to design more and more technological innovations. Again, China is leading the way. Their largest is known as the DLV4000. From the bottom of the sea depths, he is able to lift a load weighing up to 4400 tons.
Where can such cargoes be, you ask? Of course, in the places of oil and gas production. It makes more sense to lower the DLV4000 hook once than to do it a hundred times, but with a smaller machine. In addition, the world's largest offshore crane is capable of doing its job in hard-to-reach places, on dangerous shelves or in frosty 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. The crane can work continuously for 60 days, but such overheating should not be allowed. The craft can lift the submarine, as they say, with one finger, and not even blink.
The working special transport LTM 11200-9.1 can be called the largest truck crane, which is popular all over the world. It is equipped with the longest retractable telescopic boom among similar types of equipment and is a unique development of German manufacturers.
This special equipment can lift and move various cargo masses, the weight of which is 1200 tons with a reach of the boom device equal to 2.5 meters. This task is too difficult for the rest of the cranes produced on the planet.
The most powerful telescopic truck crane
The largest truck crane, the best in the world in terms of its lifting characteristics, has a retractable boom 18.3-100 m long, with a unique lattice extension, the length of which can be 24-126 meters. A similar special transport, activated by an 8-cylinder mounted on the chassis diesel engine Liebherr, running on a diesel fuel resource and equipped with a turbocharger, the power of which reaches 500 kW or 670 hp.
The crane installation is powered by a 6-cylinder engine of the same company with a capacity of 240 kW, operating on diesel fuel. The truck crane moves at a speed of up to 75 km/h and has a mass, together with a counterweight, of 202 tons.
The Liebherr LTM 11200-9.1 is 30 times more powerful than a conventional crane. The components from which it is assembled are brought to workplace 20th trucks, after which the crane is going to general design and ready to work for eight hours.
200 tons of crane weight and its working load are distributed to four paw pores, working on hydraulics. To distribute the pressure under each of these support devices, it is necessary to place platform supports made of thick iron. If the supports move, the crane may fall, which will lead to great destruction and complete failure of the equipment.
Characteristics of the Mammoth wheeled crane from the German company Liebherr
Arrows of the big truck crane in the world have strong cables that increase the power of the machine. Beneath the crane boom is a large counterweight system with 18 plates on a 22-ton base, each weighing 10 tons.
When lifting different loads, the supports are tested enough great pressure, therefore it is necessary to observe low speed this process. The truck crane control cabin contains monitors, where information about the magnitude of the load on each part appears.
The operation of the crane is controlled by operators who monitor the accuracy of operations, preventing backfire errors. LTM 11200-9.1 is used during the construction of bridges, telemasts, high-rise structures.
This unit can also load and unload equipment with large dimensions, and other types of special equipment. In addition, this crane machine used during the construction of military experimental facilities, and costs 14 million dollars.
When might a specific and unique 500 ton truck crane be used? This large technique can only be used on giant objects with heavy structures that can not be moved by equipment with a small load capacity.
The largest truck cranes, which have gained worldwide recognition, allow the transfer of fairly heavy loads, have an increased value of cross-country ability, maneuverability and cruising speed. These advantages force road construction organizations to purchase this special equipment.
These truck cranes are so expensive that it is impossible to acquire ownership and fully maintain them, so many companies consider renting a 500 ton truck crane the most the best remedy for use on a variety of construction sites.
