The new LR 1800-1.0 power pack is designed for maximum power and delivers outstanding lifting capacities. It has a passion for jobs involving a luffing jib and derrick system in industry, for power plant construction or in petrochemicals. Wind power is another of its strengths. After its initial unveiling at the customer days, Liebherr will exhibit the new crane as a highlight at Bauma 2019 in Munich.

Klaus Huberle is one of the experts when it comes to lattice boom cranes at Liebherr. In the role of Manager of Technical Sales for Crawler Cranes, he and his team initiate the design of new crane models and systems in close cooperation with the design departments. He says: “I was delighted to receive such a positive response at the customer days after we unveiled our 800-tonne crane. You can see that this is a really good concept with several innovative features.”

One of the main features of the 800-tonne crane is its extraordinary performance. The Liebherr designers focused on the rigidity of the basic machine and developed the individual components with a greater design height for this purpose. Furthermore, the lower section of the main boom has a wider design. This enables the LR 1800-1.0 to achieve particularly high lifting capacities.

“Low-cost transport ideas are becoming more and more important to our customers”, says Klaus Huberle and continues: “We looked for new solutions and for the 800-tonne crane, we developed three system dimensions for the standard crane for the first time. These are simply pushed inside each other for transport. In principle, just like a Russian doll.”

Lights, camera, action – for extremely innovative and highly flexible derrick ballast. The LR 1800-1.0 features a new type of ballast system – the V frame is a hydraulically adjustable folding frame. It enables enormous adjustment distances of between 14 and 23 metres. That delivers maximum flexibility compared to the standard rigid system for large ballast radii. With good job planning, the V frame creates an enormous range of uses and makes it possible to dispense with ballast transport.

The LR 1800-1.0 also features VarioTray – a small part of the derrick ballast can be unbolted quickly and easily. This small part is generally sufficient for hoisting work with the boom fully raised. The large ballast pallet is often only required to raise and lower the boom. This means that there is no need to stack and unstack the ballast slabs – VarioTray saves an enormous amount of time and money.
