Liebherr LTR 1220 telescopic mobile crane builds water basins for innovative energy storage system

For several months the Max Bögl Group has been working on a smart concept to generate and store natural electricity in the north-east of Baden-Württemberg. A modern pump accumulator power plant is being built near Schwäbisch Hall along with four wind turbines with a total height of up to 240 metres, making them among the tallest in the world. The special feature of this project is that each wind turbine will later be located in the centre of a circular water basin. Surplus energy can be used to pump water from the valley up into these water basins and then when electricity is then required it can be released to flow down to the power plant. The massive water basins are currently being constructed by a Liebherr LTR 1220 telescopic crawler crane. The compact telescopic crane with crawler tracks is absolutely ideal for building the massive walls of these water basins as a result of its outstanding flexibility. Positioned in the centre of the circular foundation with an impressive diameter of 63 metres, the crane has a very small footprint. From there it only has to manoeuvre a few metres to be able to reach every point of the water basin wall. The LTR 1220 is also able to move with twelve tonne reinforced concrete components attached to it. This is a massive benefit which enables the construction work to progress quickly.
