At the bauma 2019 trade fair in Munich, Liebherr will be exhibiting a lattice boom crawler crane that is used in industrial and power plant construction. It can be used to lift entire bridges. The possible hook height of around 200 meters is just one of the crane's many impressive features.
This is a lattice boom crawler crane. It has no wheels, which means it cannot be driven on public roads. This crane is dismantled and transported to the construction site on low-loaders. But this type of crane has a much higher capacity. Such cranes are used in industrial and power station construction. Entire bridges are lifted into place. We have set up a main boom system. You can see the counter jib on the right. We also have the slewing platform ballast and at the rear we have an additional ballast, called derrick ballast, which is hundreds of tons. This enables the crane to lift a correspondingly large amount at long radii.
For example, it can lift 800 tons on a 60-metre boom with a 12-metre working radius. This is an area where it really comes into its own. The crawler carrier also has a major advantage over the telescopic mobile crane. It can actually travel very slowly on the construction site with the full load. Provided that the ground is level and the load-bearing capacity allows it. A major advantage of lattice boom crawler cranes.
This is the first device. It will be delivered directly after bauma. It will be working in a chemical plant in Portugal. We have already tested the crane. It is finished and not just a prototype. We have a relatively short boom system of around 70 meters and this could even be extended up to a hook height of 200 meters. Price from around 5.5 million euros.
