The LTM 11200-9.1 is the most powerful telescopic boom crane in the world and its boom is the longest of the telescopic booms. Self-propelled boom crane with telescopic boom mounted on a special nine-axle chassis automotive type. He is the highest and most powerful crane in the world.
"Mammoth" can lift a load of 1200 tons to a height of 180 meters. There is no crane in the world capable of handling such a task. The extension of the 8-section boom to the required length and fixing it to the clamps is fully automatic. Additionally, various lattice extensions are available. Germany is the birthplace of the world's largest mobile crane.
The Liebherr LTM 11200-9.1 is 30 times more powerful than a conventional mobile crane. Parts for the assembly of the "Mammoth" are delivered to the site of the planned work on twenty trucks, accompanied by a convoy. The weight of the load and the weight of the crane itself are distributed over 4 hydraulic legs - 200 tons each. Iron supports are placed under each paw to distribute pressure. This is very important point, because if the support moves and the crane falls, this will lead to huge destruction. The crane arms are equipped with huge cables, which gives the machine even more strength. A huge counterweight system is located under the crane boom - 18 plates weighing 10 tons each are placed on a base weighing 22 tons. The crane is mainly used to install heavy loads, such as wind turbines. The length of the crane hook on the Liebherr LTM 11200-9.1 mounting block is almost 10 meters, and it weighs 11 tons.
The crane mechanisms are controlled from the control cabin, which is made of a fibrous composite material with the possibility of hydraulic adjustment in height and angle. Installed in the control cabin electronic system controls with LICCON type equipment. All chassis wheels have two braking systems: pneumatic dual-circuit with disc brakes and a ZBS type engine brake system with free release valves.
However, an unpleasant incident occurred with the LTM 11200-9.1 crane during the installation of one of the wind turbines in Germany due to a sharp gust of wind, the crane boom collapsed, but the crane itself remained on the move and, fortunately, no one was injured.

It’s not every day that you see a truck crane the height of a 25-storey building on the street, lifting a load weighing 1,600 tons to an impressive height. There are five manufacturers that produce truck cranes with a lifting capacity of over 1,000 tons.
On construction sites in low-rise construction, the use of truck cranes is not justified. heavy duty 25-50 tons heavy automotive giants are used only for "point" operations: for moving especially heavy loads, assembling industrial equipment. One can only imagine what kind of architectural monuments the ancient Egyptians would have left us as a legacy, if at that time modern giant truck cranes would have come to their aid!
This article will tell you about the largest truck cranes in the world from five manufacturers: Zoomlion, XCMG, Liebherr, SANY, Terex-Demag. The models of truck cranes they produce are among the most powerful and highest self-propelled mobile cars. If we consider giant truck cranes in analogy with world attractions, then we can mention the fact that the largest truck crane is 4 times higher than the Statue of Liberty.
Until recently, it was believed that the title "The largest truck crane in the world" belongs to the German truck crane Liebherr LTM 11200-9.1. But the Bauma China exhibition held in 2012 refuted this. Last year, she presented her giant Chinese company Zoomlion.
The largest truck crane in the world - Zoomlion
The novelty that broke all records was the ZACB01 truck crane, capable of lifting 2,000 tons! The Chinese "Maximum speed" was created on a 12-axle all-wheel drive chassis (24x24, QAY 2000). The crane is equipped with an 8-section telescopic boom 106 meters long. The manufacturer has provided for the use of four engines on the machine different power: 150, 260, 430 and 650 hp ZACB01 has a mass of 96 tons.

The release of the novelty, recognized as the most lifting and high-rise truck crane in the world, was timed to coincide with the 20th anniversary of the formation of Zoomlion.
The second line is the largest truck crane from XCMG
The second in the ranking of "The largest truck cranes in the world" is the XCMG XCA5000 crane division machine. Like its Chinese counterpart Zoomlion, the XCA5000 model was presented at Bauma China 2012. XCMG Truck Crane The XCA5000 has a lifting capacity of 1,600 tons. The development of this impressive hoist required Chinese engineers to combine seven key technologies in one crane ( intelligent system control, duplicate drive, etc.). Before the crane was released, the manufacturer had filed 50 patents.

The crane is mounted on a 9-axle all-wheel drive chassis, which is complemented by an electro-hydraulic steering servo drive and a pneumo-hydraulic suspension. A feature of the XCA5000 truck crane is the ability to move in a "crab" way, that is, sideways. The machine is capable of moving along the highway at speeds up to 80 km / h, its weight is 96 tons. The boom of the truck crane reaches a height of 105 m, and with a cantilever extension - 165.5 m.
Another largest XCMG truck crane
In its arsenal, XCMG has another masterpiece of lifting technology, which can rightfully defend its place in the ranking of the most large truck cranes in the world. This is 1,200 ton QAY1200 truck crane. Many experts note the similarity of this model with a truck crane German concern Liebherr. This is largely the result of close cooperation between the two companies.

XCMG QAY1200 was first presented at the exhibition in 2010. The car received recognition and trust of the public only after a long series of tests, the most interesting of which was the lifting in 2012 by a QAY1200 truck crane to a height of 80 meters of another QY160K truck crane with a lifting capacity of 160 tons, worth 1 million 305 thousand dollars. To complicate the experiment, a full cup of water was placed on the QY160K. The delicate work of the operator when lifting and lowering the load to the ground did its job: not a single drop was spilled from the cup.
The largest truck crane from Germany (video) - 1200-ton Liebherr truck crane
The undisputed leader in the field of crane engineering today is the German company Liebherr. For about 45 years, it has been producing lifting equipment, using the most modern technologies And engineering solutions. Liebherr's most striking "landmark" in model range became the largest truck crane LTM 11200-9.1: this model debuted at Bauma 2007. From that moment on, for several years, the company was the only one in the world to produce mobile cranes such dimensions and carrying capacity.

The LTM 11200-9.1 has a lifting capacity of 1,200 tons and is fully assembled capable of lifting loads up to 190 meters (equal to the height of a 50-story building!). To power the working mechanisms of the truck crane, it is equipped with a 6-cylinder engine with a capacity of 367 hp. Also, the machine is equipped with an 8-cylinder engine with a capacity of 680 hp, which serves to move the 9-axle chassis. The width of the crane is only 3 meters, which allows you to move freely on public roads.
The largest truck crane from SANY - SAC12000
Another giant and again of Chinese origin is the SANY SAC12000 truck crane. Despite the fact that Sany cannot boast of such experience in the production of lifting machines as the previous company, in 2010 it managed to surprise the world powerful truck crane with a carrying capacity of 1,200 tons.

The habit inherent in the Chinese to create high-quality copies of other manufacturers played a role here. The SAC12000 is similar to the German LTM 11200-9.1, although Sany says there were 23 patents built into the machine.
The largest truck crane in the Terex-Demag line (video)
Terex-Demag, one of the most experienced companies in the production of atocranes, also did not stand aside from the record numbers in terms of lifting capacity. The pride of the company in the field of building heavy duty mobile cranes is the AC 1000 model, which we also cannot fail to mention in the ranking of the largest truck cranes in the world.

The crane has a lifting capacity of 1,000 t and a boom length of 100 m. Demag has used an ovaloid boom design and the low-noise technology of the Daimler Crysler OM 501 LA engine to develop the crane. Despite the specified load capacity of 1,000 tons, the manufacturer positions the AC 1000 according to cargo characteristics with a class of 1200 tons. Experts call Terex-Demag AC 1000 a direct competitor of Liebherr LTM 11200-9.1.
The truck crane was able to demonstrate all its capabilities in 2012. A German dairy company has leased an AC 1000 to install multi-ton tankers in a dairy plant on the condition that production will not be stopped. Within a month, all the necessary tanks at the plant were installed with its full functioning.
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 biggest 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 maximum lifting capacity is required. 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.
