In Navarra, Spain, ALE has been requested by Nabrawind Technologies to find a bespoke engineering solution in order to heighten the prototype of the Nabralift self-erecting tower, one of the world’s highest wind towers. To move this 160m high and 450t tower, ALE used 12 axle lines of SPMT and 3 strand jack units for the heightening. “By providing this customised solution, our client can now how the means of developing onshore wind farms in the most cost and time effective method ever through possible. This is game-changing technology, specifically for those located on difficult-to-reach islands or mountainous sites. From our findings, we are already developing engineering processes to fulfil the requirements of future large-scale installations with an aim to develop two towers a week,” explained Project Engineer David Arias Blanco.
This project ended in September with ongoing discussions about future use of this prototype and technology. ALE was working alongside the client to develop the methodology used for this prototype for the future production of ind towers from 2019.
