We discovered one of our LRT 1100-2.1 rough-terrain cranes working on a wind farm pretty much in the dead centre of Germany, in the federal state of Hesse.

Liebherr LRT 1100-2.1 rough terrain crane at a wind farm

This powerful, rough terrain crane, which is usually seen in quarries, open-cast mines or handling heavy goods, was providing support for a lattice boom mobile crane involved in the erection of four huge wind turbines.

Our Spanish customer Aguado provided a Liebherr LRT 1100-2.1 rough terrain crane to support a large lattice boom crane. The manoeuvrable machine provided assistance to an LG 1750 on a job for repowering old wind turbines. Four 6.6 megawatt turbines built by Siemens Gamesa with a hub height of 165 metres were erected. The versatile two-axle vehicle was used both for the set-up work on the large crane and for the pre-assembly of individual components such as the nacelle. However, the benefits of the extremely manoeuvrable rough terrain crane, which can be moved whilst holding a load, really came into their own for moving the suspended ballast between the individual hoists by the LG 1750. The ballast blocks were transported quickly to the new position to take on the next load. After all, this mid-range of our three LRT models can travel with maximum loads of up to 20.9 tonnes on its hook.

Muddy paths – no problem

The rainy spring in Germany made things difficult for the team from Aguado. But even ankle-deep mud on the roads and surfaces could not stop the all-wheel drive rough terrain crane from travelling quickly and easily between the sites of the individual turbines as required. Its huge tyres with their pronounced tread meant that it always arrived at its destination quickly.

“Transportes y Gruas Aguado”, to give the company its precise name, is one of the largest transport and special haulage companies in Spain, based in the capital city of Madrid. The Aguado Group has established itself as one of the leading providers of crane services, particularly for the wind energy sector. Aguado has branch offices in Mexico, Chile, Colombia, Peru, Morocco and South Africa. Its activities extend to logistics, industry, construction, energy, petrochemicals and wind turbines – both onshore and offshore.
