Liebherr tower crane: operating principle and main technical characteristics, Liebherr 132 EC-H8 tower crane - design and characteristics

Liebherr is a group of companies known throughout the world. It was founded in 1949 by Hans Liebherr. The headquarters is located in Biberach an der Ries, Baden-Württemberg, Germany. The group includes a total of more than 130 companies around the world. They employ about 44 thousand people. The profile of activity is the production, sale and service of refrigeration equipment, port, mining, construction, and other equipment. Liebherr cranes work on a wide variety of sites, including in extremely difficult conditions (high or low temperatures, dust, excessive vibrations).

The range of products is truly huge. For example, a Liebherr port crane can be either stationary or mobile. And the Liebherr LPS series portal crane, thanks to its rotating design, is perfect for handling various cargoes. The configuration is selected individually.

Review of Liebherr truck crane models

The line of self-propelled cranes of the German company is more than wide. It contains models for a variety of client needs. Some are relatively compact. Others, on the contrary, are real giants:

1. LTC Series. Compact three-axle machine with a minimum turning radius. This quality is achieved thanks to the rotating first and third axes. Liebherr positions these truck cranes as ideal for working in tight spaces, for example, on a factory floor. The chassis is its own, the cabin is single. The lifting capacity of the only modification 1050-3.1 is 50 tons.
2. LTM Series. Truck cranes with axles from two to nine. Load capacities range from 35 to an incredible 1,200 tons. The largest of them - Liebherr LTM 11200-9.1 - at the time of showing to the public (2007) had the largest power and boom length in its class (100 m without jib).
3. LTF series. Based on standard automobile chassis of European manufacturers, at the customer's choice (for example, Scania), which can significantly reduce operating costs. The carrying capacity of a four-axle vehicle is 45 or 60 tons.
4. LRT series. Includes two modifications for 90 and 100 tons. The main feature is its high cross-country ability. This quality is facilitated, among other things, by tires with developed lugs. In addition, both axles can be rotated, so the crane can have excellent maneuverability.
5. LG series. The lattice boom structure, provided by the LR 750 crawler crane, is mounted on a wheeled chassis with eight axles. This is how the LG 1750 wheeled crane turned out, which can carry up to 750 tons with a boom reach of 7 meters.

Liebherr cranes have many models

Photos of mobile cranes

Even those who are far from the construction industry and are simply interested in technology can spend hours admiring photographs and videos of these beautiful German machines. Of particular interest, of course, are the larger self-propelled cranes, primarily the huge LTM 11200-9.1.

Liebherr LTM 11200-9.1

Characteristics

The main parameters for mobile cranes are maximum lifting capacity and maximum boom radius. They cannot be achieved simultaneously, since the crane can lift and carry a lot of cargo only with a short reach (usually up to several meters).

Be sure to read: KATO crane (KATO)

In addition, engine characteristics are important - displacement, maximum power and torque. And if “modest” self-propelled cranes have one motor, then larger vehicles are equipped with a separate diesel engine specifically to drive the crane equipment. For example, the main engine on a 750-tonne crane is an eight-cylinder with an output of 505 kW (686 hp). And the crane unit is powered by a more modest six-cylinder diesel engine with a power of only 300 kW (408 hp). Both are of their own production, although Liebherr also cooperates in this area with Mercedes-Benz.

Price

Such equipment, as a rule, is not sold at dealer sites - the order is placed and carried out individually, depending on the requirements of a particular customer. But you can focus on the price of used equipment. For example, a compact 55-ton Liebherr LTC-1055 - 3.1 from 2009 will cost 20.5 million rubles. A four-axle 100-ton Liebherr LTM 1100-4.2, 2006, costs about 66 million rubles with all taxes. And for the giant Liebherr LTM 11200 - 9.1 of the same 2016 release they are already asking 335 million rubles with delivery by sea to Russia, but excluding customs duties.

Specifications

Such indicators as a boom reach of up to 60 m, a load capacity of 6 to 10 tons, and a height of 201 m make these technical equipment ideal for working in confined spaces.

One of the obvious advantages of the described technical means is the use of powerful drives in them.

The crane is equipped with a 1-, 2-, 3-stage winch, a rotating mechanism, and a trolley winch, which are equipped with a frequency converter that ensures smooth execution of all working actions.

The towers of Liebherr units are made of hermetically welded racks and diagonal braces. At each corner joint, the connection is made with 2 forged stamped fasteners and 2 tension bolts.

All this ensures high strength and absolute reliability of the tower systems of the mentioned brand.

Also, the faucets of the described manufacturer, produced for Russia, are necessarily equipped with such special options as thermal control, which provides for turning off the operating mechanisms of the equipment when the temperature reaches -25 ° C.

You can buy a new technical product from the described brand from 19 million rubles, a used model of this type of equipment costs from 10 million rubles.

If purchasing such a unit is not practical, you can use the services of numerous companies offering to rent a Liebherr tower crane.

So, for the 200th model per month you will have to pay about 200 thousand rubles. The average price of such a service per month will be 350 thousand rubles.

Review of Liebherr tower crane models

Liebherr is the world's largest supplier of tower cranes. The largest construction projects in the world trust this company. In particular, 55 such cranes were used at once for the construction of Istanbul Airport. The line includes dozens of different models. For example, the Liebherr single tower crane, due to its low height, is more suitable for working under high-voltage lines and in intersecting work areas. Another advantage is the fastest and simplest installation. Thus, it can be brought into working order in a short period of time and, in addition, with a minimum number of employees. All this is saving resources.

The modular design allows each unit to be custom-made to be as efficient as possible under specific conditions.

If you look at photographs from construction sites around the world, you will almost certainly see Liebherr cranes.

Specifications

Depending on the specific modification, a liebherr tower crane can carry from one and a half to 50 tons. The maximum boom reach varies from 50 to 81.5 meters. In addition, there are many more parameters that influence the choice of one design or another.

Review and application in practice

The manufacturer offers a large selection of Liebherr mobile pneumatic wheeled and crawler cranes, among which are the following:

• mobile units of the LTM series: 1030-11200;
• small-sized devices of the LTC series: 1050;

Crawler crane models include the LR and LTR series with a telescopic boom. The maximum lifting capacity of the equipment is 3000 tons.

The most common model among users is the Liebherr LTM truck crane with a large ballast radius and an all-terrain all-terrain chassis, which affects its mobility and guarantees movement even on unpaved roads. Thanks to VarioBallast technology, the device can be used in tight and confined areas at night.

Liebherr self-propelled cranes are equipped with powerful Liebherr turbodiesel engines with minimal emissions of harmful substances.

ZF gearboxes are automated and economical. The following factors influence this:

• a large number of switching speeds and a dry clutch lead to lower fuel consumption;
• the presence of a 2-speed gearbox on LTM cranes with 3-5 axles allows you to reduce the slow motion speed and increase maneuverability;
• ZF-TC Tronic gearbox with installed torque converter on LTM models;
• ZF 6WG gearbox under load in folded state and installed converter on LTM and LTC with 2 axles;
• a large number of driving axles.

The braking system is characterized by instant response, smooth braking and reduced performance.

The axles are equipped with Niveaumatik hydropneumatic adjustable suspension, which increases the axle load and improves lateral stability when turning.

For large mobile cranes with 5 or more axles, the crane drive is installed from the chassis engine.

ECO mode is designed to reduce noise and reduce fuel consumption.

The cranes have a Liccon control system with a variable support base, as well as VarioBase technology for accurate load capacity calculations.

The cabin is spacious, comfortable and ergonomic. The driver's soft seat is vertically adjustable and contains a headrest and air support for the lumbar region. Large windows and tinted glass increase visibility. The exterior mirrors are electrically adjusted. The steering wheel is adjustable in all planes. The panel contains multifunctional control devices and indicators.

For comfort during work, ventilation and heating systems have been developed.

The reliability of lifting machines has been proven in practice.

French manufacturer SE Levage presented the operation of the LTM-1300 crane at 12 o'clock at night when lifting a racing yacht to a height of 60 m to the Eiffel Tower gallery in Paris. The advertising medium was installed in pre-assembled mounts.

Wasel GmbH from Bergheim demonstrated the dismantling of large suspended scaffolds at Cologne Cathedral at a height of 100 m using a Liebherr LTM-1750 crane with a maximum hook lift of 154 m.

In the Swiss canton of Valais, with tight bends and steep, gravel-strewn inclines, the LTR-1060 crawler crane proved its off-road capability and maneuverability. He reached the construction site at an altitude of 2022 m along a difficult 920 m high mountain section for the expansion of the Gornergrat rack railway tunnel.

Liebherr truck cranes 300 and 500 tons

The design of lifting and transport machines with a lifting capacity of 300-500 tons is increased by a specially installed Y-portal.

The main difference between Liebherr 500 ton cranes and 300 ton models are the operational parameters of the telescopic boom and the lifting height.

Thus, the length of the switch device for 500 t is 84 m, for 400 t - 60 m, for 300 t - 78 m.

The lifting height for 500 t machines reaches 142 m, for Liebherr 400 tons - 130 m, and 300 t - 114 m.

LTM 1100, 1200, 1300

Liebherr LTM 1100, 1200 and 1300 mobile cranes have lifting capacities from 100 to 300 t.

For the Liebherr LTM 1100, the technical specifications are as follows:

• telescopic boom - 11.5-52 m;
• extension cord - missing;
• engine - 370 kW;
• travel speed - 80 km/h;
• counterweight weight - 35 t;
• machine weight - 60 tons.

The Liebherr 1300 crane differs from the 1100 model by the presence of a boom extension and a more powerful diesel engine. The weight of the counterweights is 112.5 tons.

The Liebherr LTM 1200 truck crane has a lifting capacity of 200 tons with a reach of 3 m.

The particularly powerful and heavy Liebherr LTM 11200 tower cranes on a 9-axle chassis with a lifting height of 188 m are designed for 1200 tons. The Liebherr LTM 1050 crane is simpler and more convenient in the line.

Features of the device and operation

1. Highest possible lifting capacity in its class compared to other four-axle mobile cranes. Powerful telescopic boom, extended with lattice sections and a two-section folding extension. Safe and economical driving is ensured by rear axles with active steering and pneumatic disc brakes. A wide range of accessories included in the basic package. The equipment uses the most advanced technologies to increase functionality
2. The chassis is a six-cylinder unit with a turbine. Engine power is 476 horsepower, and torque reaches 2230 N/m. Power is transmitted through a German-made ZF AS-Tronic automatic transmission. Due to the large number of gears (12 forward speeds and two gears for reverse), it was possible to achieve class-leading fuel efficiency. In addition, we note another important element of the chassis - a two-stage transfer case with a deceleration speed of 0.46 km/h. The kit also includes drive axles 2, 3 and 4. Axle 1 is optional. Among the auxiliary electronic systems, we note ABV technology, which automatically prevents the brakes from locking
3. Maneuverability and smoothness worthy of the heavy class are due to the compact chassis 10.6 meters long. The turning radius is at least 8.3 meters. The truck crane is equipped with tires with parameters 16.00 R 25. The counterweight has a turning radius of 4.1 meters
4. Niveaumatik hydropneumatic suspension – requires maintenance only when necessary. It has a high safety margin even with a load of up to 40 tons per axle. Stable chassis when cornering and a wide range of operating ranges
5. Steering, programmed for five operating modes. The instrument panel has an ergonomic arrangement of levers, switches, indicators and service elements
6. Built-in security system with two independent processors that read readings from instruments and sensors and display information on a central display located in the operator's cab. Thus, the driver is always aware of the status of all instruments and moving parts. If any of the readings deviate from the norm (for example, if the permissible load is exceeded, the pressure drops or the temperature is high), the driver will be able to correct the problem in advance, and thereby prevent the occurrence of larger problems
7. Multifunctional cabin with high quality finishing materials. It has an anti-corrosion sheet steel structure, full protective glazing with tinting, heated and electrically adjustable mirrors. The cabin is also equipped with a seat with pneumatic height adjustment. The driver's cab and operator's cab have similar design and materials.
8. Possibility of installing the crane on supports using electronic control. Supports allow you to achieve the maximum permissible load capacity
9. Six-section telescopic boom – extends to several specific positions depending on the complexity and type of operation. The maximum length is 60 meters. The boom comes with a 19 meter extension. With a boom length of 60 meters, the crane’s lifting capacity reaches 10.2 tons. Load capacity can be optimized with multiple telescoping options
10. Built-in data bus, which is an analogue of a “black box” - an on-board recorder, with the help of which the operation of the truck crane is recorded in real time, and throughout the entire service life of the product.

Parameters of the German leader

The Liebherr LTM 1100 is designed for 100 tons and belongs to the group of 4-axle mobile cranes, the maximum boom height distance is 91 m. The following performance characteristics are typical for this mobile crane:

To move steadily, the truck crane is equipped with 9 main axles, which are controlled by 18 wheels. Liebherr has high fuel efficiency thanks to 12 gear speeds and two additional ones for reverse. The truck crane involves automatic brake locking, achieved using ABV assist technology. Traction is transmitted using an automatic transmission, and slow speed is provided by a two-stage transfer case. Deceleration speed - 0.46 km/h.

The security system, equipped with two independent processors that read data from sensors, deserves special attention. All information is reflected on the central display, and the operator can always monitor the status of all components and systems. The steering of the truck crane, characterized by five modes and ergonomic placement of levers and switches on the dashboard, also simplifies the operation.

Advantages

The design features of the model range of the described Liebherr special equipment make it possible to operate this equipment during the construction of buildings of any configuration and degree of complexity.

The technical means under consideration have a number of advantages:

• modularity – the ability to quickly install sections of equipment within identical series allows you to obtain a configuration that satisfies specific consumer needs;
• the speed of moving and lifting loads , as well as the speed of changing the boom reach, has been optimized to 116 m/min;
• reduced energy consumption (2-3 times less than that of domestic analogues) of 80 kW allows you to do without additional power supplies that require installation, which significantly reduces production costs;
• low noise level during the working process allows the equipment to operate in residential areas;
• the cranes maintain excellent performance even with wind gusts of 20 m/sec. at the level of the driver's cabin;
• a rotating mechanism equipped with a fluid coupling guarantees the smoothest possible movement, high accuracy of aiming and lowering the load;
• optimal comfort and ergonomics of the operator’s workplace guarantee excellent concentration and prevent rapid fatigue;
• easy installation due to well-thought-out fastening systems.

The speed of this equipment allows saving up to 30-35% of the working time spent on the construction of buildings, especially for the construction of high-rise structures.

Due to the fact that some Liebherr tower cranes do not require the installation of rail tracks , it becomes possible not only to significantly save the usable space of the construction site, but also to avoid a lot of technical actions necessary when installing equipment on the specified track.

You can find out how the KS-45717-1 truck crane is designed and what technical characteristics it has in our article. A review of KB-405 has been prepared for you.

Transportation of all modular parts of the cranes is carried out without any difficulties, since all of the designated structural elements have optimal overall dimensions and do not require the use of special means for their transportation.

Ease of operation coupled with the latest software allows you to control the operation of the cranes with extreme precision while achieving the highest level of safety.

Thus, this is facilitated, in particular, by the electronic control system EMS, which is mandatory installed on all tower units of the designated manufacturer.

Most models of the described category of Liebherr equipment are installed on an anchor foundation, which includes a support frame and a cross base.

Series LR

This includes a wide range of lattice boom crawler crane models that are capable of delivering construction materials to heights of up to 223 metres. The maximum load weight depends on the exact crane model and modification.

The main features include the low weight of all parts, the possibility of self-unloading and assembly, and optimization of load capacity and maximum working height. This ensures the safety of surrounding objects, the construction crew and the safety of the structure itself.

Photo of crawler crane LIEBHERR-LR-11301

When developing the Liebherr LR series cranes, engineers used the most modern methods and technologies, which made it possible to achieve optimal operational safety and high maneuverability of the crane, even when working with dangerous and very heavy loads. This range includes the LR 1280, 1100, 1300 and 1130 cranes.

We consider the technical characteristics of Liebherr LR series crawler cranes in the table:

Each LR series crane model meets not only safety requirements and building regulations, but also satisfies the desires and needs of each customer. Everything here is done as conveniently and comfortably as possible.

Mobile cranes LTM series: All-terrain cranes that set standards.

LTM mobile cranes with off-road chassis are ideal for driving on public roads and rough terrain. They are safe, economical and comfortable.

The powerful and long telescopic booms reach high working heights quickly and easily. Flexibility is a top priority when equipping a crane: The appropriate crane for any application can be quickly assembled from functional lattice sections, extensions, fixed and folding lattice extensions.

With approximately 25 LTM cranes at our disposal, from small 2-axle to large 9-axle, we offer the right crane for every application. We are constantly improving our cranes: VarioBase, VarioBallast, LICCON crane control or telematics are just a few of the innovations from Ehingen, home to the most modern crane production in the world.

In the process of technological progress, we always strive for modernization and offer the latest technologies for existing cranes.

Equipment Features

Advanced developments are used in production to ensure accuracy and safety when performing work:

• LICCON is a computer control and monitoring system. It is Liebherr's own development. It has the ability to adjust parameters for a specific model. Adapted for use in extreme temperatures.
• Telematic is a mechanism for automatically extending boom sections. Provides high speed and the required working height.
• VarioBase is a device for additional outriggers that increase technical parameters and accuracy of work in cramped conditions.

Model range of Liebherr truck cranes

The company covers the entire range of types of self-propelled cranes; the following series exist:

LTM - telescopic cranes on off-road chassis. In addition to the fact that the machines can pass on any ground (this is not uncommon on our construction sites), they also have high speed when driving on the highway. The most powerful telescopic crane in the world is the Liebherr truck crane Liebherr LTM 11200-9.1 (Liebherr truck crane 1200 tons).

LTF - construction taxi cranes, differ in that they can move loads without extending and fixing additional outrigger supports. A crane that arrives at the site is immediately ready to begin work, which gives them a tangible advantage in the case where the crane’s operating mode does not require constant presence in one place, but requires constant movement to perform short-term work.

Description of the Liebherr LG 1750 truck crane

LG - high-capacity cranes with a lattice boom. New 750 ton self-propelled lattice boom crane. Liebherr has expanded its range of heavy self-propelled cranes with the LG 1750 lattice boom crane.

It combines the flexibility of a 750 tonne crawler crane with the mobility of a fast moving truck crane in the same lifting capacity category.

For the LG 1750, Liebherr used the slewing crane and jib system of the LR 1750 crawler crane, as well as a completely newly developed six-axle compact chassis with a modern design. Four very strong and large folding beams form a star-shaped support with a support base of 16 x 16 m. They dominate the appearance of this special crane chassis. Table 1 - Technical characteristics of the Liebherr LG 1750 truck crane

LTC - compact telescopic cranes. Thanks to the special design of the chassis and lifting mechanism, they are able to work in cramped conditions, which is not uncommon on modern construction sites with dense urban areas. This ability of the machines also allows them to be used effectively when performing emergency repair work on various communications.

MK - self-propelled tower cranes. Unlike traditional cranes of this design, which move on rails, they can reduce the time required to set up a construction site and, consequently, the construction time of the facility.

General description of Liebherr truck cranes

Liebherr truck cranes are made on the basis of a chassis created by the company itself, which distinguishes them from other manufacturers who mount their equipment on vehicles from other companies.

This means that the Swiss equipment is maximally adapted to the tasks it performs and eliminates all sorts of complications associated with the fact that, for example, when operating crane equipment, the engine or transmission of a machine intended for highway driving operates in abnormal mode.

Also, the Liebherr brand has a very powerful design bureau that uses all the latest achievements of science (this is confirmed by the fact that the second-largest mining dump truck after BelAZ is assembled on the company’s assembly line). It is also worth noting that Liebherr is not imported equipment, the company's divisions are located in the Nizhny Novgorod and Moscow regions.

Liebherr range

Two main groups of the technology under consideration can be distinguished. LTM models are wheeled, all-terrain crane units with a telescope boom. The units are designed to move over difficult soil and public roads. This series presents the most powerful modification among telescopic “lifts”

The LTF line includes mobile construction cranes. They can transport loads without installing support outriggers. The equipment is ready for work immediately after arriving at the site. This is a big plus if you expect to change objects frequently.

The modifications differ from each other in different load-carrying capacities.

Technical characteristics of Liebherr truck cranes

This type of equipment is produced on the basis of chassis manufactured by Liebherr. Such truck cranes belong to the category of self-propelled equipment and can move under their own power along public roads without the need to use additional equipment for transportation.

The wheelbase itself is equipped with a multi-axle suspension, where each axle has its own independent control, thereby increasing maneuverability and cross-country ability. When moving along roads outside construction sites, such truck cranes can move at speeds of up to 80 km/h. All this allows you to save time and resources for moving the crane.

The features of the crane control system make it possible to control the movement of the truck crane boom with the highest precision, while the error in the movements of the moving elements of the boom is only a few centimeters.

Separately, the designers were faced with the task of providing the operator of the equipment with maximum comfort during the work process. Hence, convenient controls, air conditioning and heating in the cabin, as well as safety features and a cabin with a large glass area that increases viewing angles.

Approximate prices on the Russian market

The Liebher company has production facilities in the Russian Federation. This reduces the cost of equipment and ensures fast delivery of modular units or individual spare parts. The cranes outperform competitors in all respects due to their high quality and performance characteristics, while the price is only 15-20% higher than their Russian counterparts. The estimated cost is from 15 to 110 million rubles. The final price depends on the region, model, technical condition, year of manufacture.

Liebherr wheeled mobile cranes have proven themselves well in the global and domestic markets. German quality is combined with high performance, reliability, and safety. Not the least factor in favor of this technology is the comfort and information content of the operator’s seat.

Market position and prices

Due to the fact that the company has production on the territory of the Russian Federation, you can buy a Liebherr truck crane in your homeland. The equipment successfully competes both in price and even more so in quality with the products of domestic machine builders. In fact, Liebherr truck cranes are the most popular and widespread self-propelled cranes in Russia, produced by a foreign company. All this has been achieved with high performance characteristics and reasonable cost (only 10 - 20% higher than Russian cranes).

Load capacity and other properties of the Liebherr crane

German manufacturers produce several models of Liebherr cranes with a tonnage of 40, 50, 70, 100 tons. The Liebherr LTM 1100 truck crane has the maximum lifting capacity. In general, lifting capacity indicators depend on the height of the boom and have the following ratio:

Load capacity of Liebherr LTM 1100

• 11.5 m – 100 t;
• 15.2 m – 65 t;
• 26.4 m – 51.3 t;
• 33.9 m – 32.8 t.

The Liebherr mobile crane's lifting capacity is increased by many telescoping options. High load capacity allows you to transport large-sized equipment and fragile items in a vertical and horizontal plane. Electronic control allows you to install special supports on the truck crane, due to which the maximum possible lifting capacity increases.

The special vehicle has a built-in data frame, like an on-board black box, which records the operation of the crane in real time. The mobile crane's maneuverability and compactness are ensured by its turning radius, which is 11.01 on all-wheel drive. The counterweight has a turning radius of 4.1 m.
