Vestas se lance dans les tours hybrid

Tout est dans le titre, après Enercon c'est au tour de Vestas de se lancer de la réalisation de tour hybrid (béton/acier).
Et ce n'est pas sur une petite longueur: 140m!
Il n'y a pour le moment que 3 prototypes de V112 équipés de ces tours en allemagne. La grue est juste effrayante


[size=200:2ylpfumg]First hybrid tower installed

Last week Vestas’ first hybrid tower with a hub height at 140m was installed at the Bischberg site, Southern Germany using a new crane concept.


This first installation is a part of the contract signed with the German company Max Bögl to develop and buy three prototypes of the V112 turbine using a hybrid tower design. The three V112 turbines are now being installed at the Bischberg site, which is near Max Bögl’s corporate HQ in Neumarkt, Germany.

New crane concept
Usually mobile cranes are used to lift the steel sections when installing turbines. This time Max Bögl has invested in two standard stationary cranes. This saves a lot of space at the site due to less crane pad needed as the crane is mounted directly on the foundation.

Facts about hybrid tower
Hybrid means that the tower is partly made of concrete and partly of steel. In this case the tower is 140 meters - 82 meters of the tower is concrete and 58 meters is made of steel. This specific hybrid tower is developed to lower costs and stay competitive in the low wind market in Europe. Concrete is cheaper and independent of the flexible steel prices, and therefore it makes sense to use a hybrid design for high hub heights.
