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
Most big truck crane, the best in the world in terms of its lifting characteristics, has a retractable boom with a length of 18.3-100 m, with a unique lattice extension, the length of which can be equal to 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
The booms of the largest 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.
Most large 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 they cannot be purchased and fully maintained, so many companies consider renting a 500 ton truck crane the most the best remedy for use in a variety of construction sites.
To date, the most powerful crane in the world is a telescopic crane model LTM 11200-9.1, it has the longest telescopic boom in the world. Maximum load capacity crane is 1,200 tons with a reach of 2.5 meters. The length of the telescopic boom ranges from 18.3 meters to 100 meters. The length of the lattice jib ranges from 24 meters to 126 meters. Crane travel speed up to 75 km/h. crane weight in transport position is 96 tons, and the total weight of the counterweight is 202 tons. This German "Mammoth" is used at large construction sites of factories and ships.
Arrow "Mammoth" has eight sections, automatically put forward to the desired length and height.
"Mammoth" is graceful, beautiful and does not look like a mammoth at all.
LR13000
Another giant is crawler crane The self-propelled LR13000 is the largest mobile crane in the world. The machine is capable of lifting a weight of 3000 tons to a height of 12 meters! Once, a load weighing 3317 tons was lifted by a crane - an absolute record for this type of transport! This crane is used in the construction of powerful chemical and oil plants.
The crane's lifting hook measures 9.7 meters and weighs 111 tons. The hook can lift the load up to 270 meters. Let's imagine a building with 74 floors... This is the approximate height of the lifting hook! This crane is the most high crane in the world!
XGC88000
The world's largest crane is being developed Chinese company XCMG. It will have a lattice boom capable of lifting 3,600 tons with a maximum load moment of 88,000 tm. The crane will have a model code name - XGC88000. This is not the first large-scale project of such a machine. Large cranes have been produced in China for a long time. Future Development will help in the construction of the coal, chemical and oil industries and in the construction of powerful nuclear power plants. The height of this crane is 130 meters, and the average lifting height is 80 meters. The Chinese did not stop there and continue to improve their technical developments. Congratulations!
But cranes are not only land-based! The largest floating crane in the world is also developed in China. Its carrying capacity is 4400 tons, the design speed reaches 12 knots.
We have considered only some of the most big cocks in the world. In fact, there are many more. beautiful, powerful, tall cars- assistants in the most complex construction of "factories, ships" will delight our eyes with new records more than once.
Considering that tower cranes are inferior in terms of lifting capacity to both crawler and truck cranes, which are a mandatory attribute in any modern construction. Tower cranes can be placed on the ground or on a structure and can easily carry materials to great heights and deliver them to any place on the structure under construction.
Tower crane Kroll K-10000
As the highest in the world, the Kroll K-10000 can be noted - this is a technique that has actually become historical. But it is not intended for building houses. This type of cranes are widely used in power buildings, mainly during the construction of nuclear power stations, and has proven itself in the construction of facilities that require a large number of mounted elements having a mass of more than 240 tons. The production of the K-10000 was stopped after the construction of nuclear power plants was curtailed by the end of the eighties.
Given this, some pieces of equipment are still working in some countries, and each of them has a history. By design, the tallest tower crane in the world is a two-tower self-propelled equipment, which has a rail course. The height of the entire structure, which consists of two cranes of the main and auxiliary type, is 143 m. The boom can be thrown up to 84 meters.
Zoomlion - lifting capacity of 240 tons
But in 2010, the public learned about the plans of the Chinese company Zoomlion to release a top-slewing tower crane, which would have a lifting capacity of 240 tons, from the very great height work in 210 meters.
Then the company made a statement that the operation of this type of machine was carried out during the construction of a pylon for a suspension bridge that passes through the Yangtze River, where it also passed the test of lifting to the highest weight of the load. But the exact data about the development of engineers from China have not yet been published.
Among the other cranes, it is worth noting the high tower crane , which is operated on most construction sites in the world - Heavy load 4000 HC 100. Its carrying capacity is 100 tons. This model of crane was specially designed to lift loads to great heights.
Thus, this crane can lift more than 22 tons at 96 meters.
