Tadano CC 78.1250-1 Erects 199-Metre Hub-Height Wind Turbine
30-Second Takeaway
Steil Kranarbeiten used its Tadano CC 78.1250-1 lattice boom crawler crane to help erect a 7.2-megawatt wind turbine at Winnberg, near Sengenthal, Germany. The turbine has a 199-metre hub height and stands 285 metres tall overall, making it the world’s tallest series-produced onshore wind turbine, according to the project team. The crane was configured with a 203.5-metre main boom, Tadano’s Boom Booster and a 15-metre fixed jib. The challenging setup included sloping ground, and the crane’s footprint measured 12 by 13 metres.
Crane Configured for High-Hub Turbine
The turbine, developed with Vestas, is installed on a hybrid tower developed by Max Bögl. Its 199-metre hub height required a crane configuration capable of working at an exceptional height.
Steil selected the 1,250-tonne-class Tadano CC 78.1250-1, configured with a 203.5-metre main boom and Boom Booster reinforcement structure, plus a 15-metre fixed jib. Crane operator René Perlich said the company chose the machine because it could erect a turbine of this type.
The CC 78.1250-1 was the first crane of its kind in Europe. Tadano provided an on-site service team to support assembly of the configuration, which Steil described as the first of its kind worldwide.
Boom Booster Supports Assembly and Transport
The Boom Booster reinforcement structure was central to the crane’s long-boom arrangement. Its components can be folded for transport, then unfolded and bolted together at the jobsite, avoiding special transport arrangements for the structure.
Assembly took place on sloping ground, but the crane’s compact footprint of 12 by 13 metres helped it fit within the available site area. Perlich also noted that, despite its scale, the CC 78.1250-1 handled much like Tadano’s smaller CC 38.650-1.
Renewable Output for Max Bögl
Once commissioned, the turbine is expected to generate approximately 17 to 18 million kilowatt-hours of electricity annually. Combined with Max Bögl’s existing power-generation systems, it is expected to cover about two-thirds of the group’s energy needs at its Sengenthal headquarters.
