Modern precast technologies have been and are still widely used in the construction of wind turbine towers at very notable engineering levels. Nowadays, in the pursuit of the highest performance, wind farms with significant high towers, up to 120 m, are erected. Due to these heights, the precast concrete towers were found to be more efficient, cost-effective and durable than the steel ones that have so far allowed the achievement of an 80 m limit.
On the market, there are several system for producing concrete wind turbine towers but not all of them envisage the manufacture of precast sections to be assembled on site. This operation is rather complex due to the significant weight of the elements themselves and the great altitude. For this reason, precast sections need to be accurately dimensioned and this can only done by use of specific formworks with minimum tolerances.
