MM1018 secures the commissioning of an Enercon hybrid tower in Gardelegen

Modern wind turbines with hub heights of up to 150 metres enable significantly higher energy yields thanks to hybrid tower technology. However, these advantages are accompanied by a considerably higher and permanent load on the tower construction.

The hybrid tower has a modular design and is erected on a solid concrete foundation. A tension ring (load ring) with threaded bolts ensures stable anchoring in the ground. The foundation not only transfers the load, but also dissipates lateral forces.

A common problem is the formation of gaps between the clamping ring and the attached lower steel segment. This can be up to three millimetres and jeopardises the safe commissioning of the tower.

At the Gardelegen wind farm (Sachsen-Anhalt), this problem was solved by reliably levelling out the gaps with our MM1018 – The Liquid-Shim® – thus ensuring the operational safety of an Enercon hybrid tower.
