History and Evolution of Liebherr Tower Cranes
The Founding Story
The story of Liebherr tower cranes began in 1949 when Hans Liebherr revolutionized the construction industry by developing the first mobile tower crane. His innovation, born in post-war Germany, laid the foundation for what would become one of the world's leading manufacturers of construction machinery. The company's commitment to quality and innovation has remained unchanged since those early days.
Key Milestones in Development
Throughout its history, Liebherr has achieved numerous breakthrough moments. The 1970s saw the introduction of the first hydraulic fast-erecting crane, while the 1980s brought computerized control systems. Each decade has marked significant advances in lifting capacity, reach, and technological sophistication.
Types of Liebherr Tower Cranes
Top-Slewing Tower Cranes
Top-slewing cranes represent Liebherr's flagship models. These powerful machines are characterized by their ability to rotate 360 degrees at the top of the tower. Models like the EC-H series offer exceptional lifting capacities ranging from 6 to 40 tonnes, making them ideal for major construction projects.
Fast-Erecting Tower Cranes
The fast-erecting crane series, including the popular L1-24 and L1-32 models, provides rapid deployment solutions for smaller to medium-sized construction projects. These cranes can be operational within hours, offering remarkable efficiency for time-sensitive projects.
Mobile Construction Cranes
Liebherr's mobile construction cranes combine the mobility of a conventional crane with the functionality of a tower crane. The MK series exemplifies this versatility, offering quick setup times and impressive lifting capabilities.
