First of Five: Max Bögl Takes Delivery of Liebherr LTM 1750-9.1 for Wind Power

Five cranes for the energy transition

Bögl ordered the five 750-tonne cranes at the start of the year; the remaining four will arrive in stages by February 2027. CEO Stefan Bögl travelled to the Liebherr plant in Ehingen in person for the handover of the first unit, underlining what the investment means for the company’s in-house construction machinery fleet.

“Thanks to their high lifting capacity and rapid deployment, the newly acquired mobile cranes are perfectly suited for use on our wind farm construction sites.”

Hybrid towers: concrete meets steel

Max Bögl is Germany’s market and technology leader for hybrid wind turbine towers, which combine a concrete lower section with a steel top. The concrete tower alone is assembled from more than 30 individual rings — up to 60 tonnes each and up to 12 metres in diameter — and can reach 110 metres.

Baptism of fire in Papenburg

The first LTM 1750-9.1 went straight from the factory to Papenburg in northern Germany, where it has 17 weeks to erect 20 concrete towers for turbines with 164-metre hub heights. That means lifting loads of up to 56 tonnes to 86 metres, with the 52-metre telescopic boom extended by lattice sections to a roller head height of around 100 metres. Site manager Florian Herdegen reports that positioning the concrete rings with millimetre precision — in changing weather — is running smoothly.
