Autodienst Eineder GmbH has been using an LTR 1060 since October. The Liebherr 60 tonne crane does most of its work in solar parks. The Bavarian company exploits the strengths of the telescopic crawler crane for the economical installation of transformer stations – off-road capability, manoeuvrability and the ability to travel with a full load mean less time and lower costs.
Managing Director Peter Eineder explains: “Its off-road capability and manoeuvrability makes the LTR 1060 ideal for jobs in solar parks. Its “pick & carry” mode is particularly good as it enables us to carry transformer stations weighing up to 20 tonnes straight from the transport vehicle to the installation site.” If the terrain means that the LTR 1060 cannot carry the load over it, Eineder uses a heavy duty transport crawler to move the transformer stations to the solar parks.
Their design means that crawler cranes can travel on site with a full load on their hook. The crawler chassis also makes it easy to master difficult terrain. In addition to the 4.8 metre wide track, the Liebherr LTR 1060 can also work safely on a track width reduced to 3 metres using the crane control system. “That is a major benefit on constricted sites. We also appreciate the sensitive control of the LTR 1060 when things are tight”, continues Eineder.
The Managing Director of the company based in Ingolstadt also praises how easy it is to transport the 60 tonne crane. The crawler travel gear can be retracted to a width of 3.0 m for transport. The low crane height of just 3.15 m ensures that economical standard semi low loaders can be used. The LTR 1060 weighs just 62.6 tonnes complete with turntable and central ballast. The axle loads for transport are less than 12 tonnes for a 3-axle tractor unit and a 5-axle low loader. By removing ballast, the transport weight can be reduced to the net weight of the basic 37.5 tonne machine. Axle loads of less than 10 tonnes can be achieved using a 3-axle tractor unit and a 4-axle low loader.
Once at the site, the crane can assemble both the central ballast and the slewing platform ballast itself without requiring an auxiliary crane. “The LTR 1060 is a fantastic crane. Even as a 40 tonner without ballast, it is perfect for many jobs, including installing small transformer cabinets”, adds Eineder.
