The holding company is Liebherr-International AG based in Bulle, Switzerland, whose shareholders are all members of the Liebherr family. In short • 41,000...

Liebherr Tower Cranes The invention of the mobile tower crane in 1949 marked the start of Liebherr Tower Cranes. This product division within the Liebherr Group of Companies is now the leading global manufacturer of mobile construction and tower cranes and has five production plants in Germany, Spain, India, Brazil and Russia. Its range of products includes an extensive program of high-quality tower cranes featuring all systems and size classes. They include fast-erecting, top-slewing, luffing jib and special cranes. The flexible fast-erecting cranes and powerful top-slewing cranes are...

Fast-erecting cranes The L1 series The hydraulic fast-erecting cranes in the L1 series deliver the solution for two of the most important challenges on a site: the power to move heavy loads without taking up too much space. In short: Compact power. Their compact design makes them ideal for constricted sites, such as house building and roofing work with a limited area. A version with full steel ballast ensures costeffective and fast transport and erection procedures. The cranes can be made ready for use quickly thanks to their easy-assembly hydraulics. The company’s own control system...

Fast-erecting cranes The K series The K series is notable for its combination of versatility and flexibility. K cranes adjust to the site situation with variable hook heights, lifting capacities and slewing radii. This is made possible by the telescoping lattice tower with rapid climbing equipment, the adjustable jib and reducible slewing platform. The crane driver can see everything all the time – whether he is using the practical remote control on the ground or in the modular crane cabin. Liebherr’s own powerful drive units and intelligent control systems enable a high handling capacity...

Mobile construction cranes The MK series The mobile construction cranes in the MK series combine the mobility of a classic mobile crane with the functional benefits of a tower crane, such as working on projecting edges. The enormously manoeuvrable taxi cranes in the MK series are designed for one-man operation. The crane driver can drive, erect and operate the MK crane using the remote control or in an infinitely height-adjustable elevating operator’s cab. The vertical tower enables the crane to get very close to the building so that the entire jib length can be used at all times. With...

Top-slewing cranes The EC-B series The EC-B series was specially developed to meet the requirements of modern construction sites. Transport, erection, handling capacity and safety – the intelligent overall concept delivers progressive solutions in every category. Compact transport units and efficient erection solutions such as the sophisticated compact head, LiConnect quickrelease connections for the jib and counter-jib and safe electrical plug connectors ensure a high level of cost-effectiveness for transport and assembly. Various climbing and guying systems mean that there is almost no...

Top-slewing cranes The EC-H series The cranes in the EC-H series dominate the image of many building sites with the unmistakable silhouette with the tower head and interior cabin. These high-top cranes are ideal for medium and large construction projects, such as industrial and plant construction. EC-H cranes are the best option for high lifting capacities. The heavy-duty drive units made by Liebherr also ensure high handling capacities. Various climbing and guying systems mean that there is almost no limit to the possible uses. All EC-H cranes with the Litronic control system can be...

Top-slewing cranes The HC-L series The luffing jib cranes in the HC-L series are used for high level work on constricted sites. They can be used on almost any site as a result of the small slewing radius and luffing jib, even if there is little space available. With high lifting capacities and fast hoist speeds, they ensure that building work proceeds quickly. In the luffed position of the jib between 15° and 70°, even when not in use, they can be slewed freely when used on sites with lots of cranes and overlapping slewing ranges. Various climbing and guying systems mean that there is...

Top-slewing cranes The HC series The HC series comprises large cranes designed for very high hook heights and very large radii which can manage enormous lifting capacities. These cranes are often used over a long service life, for example for handling loads at mines or shipyards. HC cranes can position even very heavy loads precisely and sensitively. The company’s own drive units and control technology ensure that the drive units are perfectly tailored to each other and that sensitive loads can be positioned correctly. Tower Cranes

Special cranes Tower cranes on crawler tracks Fast-erecting cranes and top-slewing cranes are available on crawler track travel gear for difficult terrain. These cranes with crawler undercarriages are extremely mobile and therefore particularly cost-effective. Crawler cranes are used when cranes have to be able to change location quickly and also generate low ground pressure. The expertise from three Liebherr companies was used in the crawler undercarriage. further cranes on request Tower Cranes
