Lanaro has developed and produced in cooperation with its customer, the steel structure of number 3 station roofs for the Olang II single-wire ski lift, a particular architectural curved constructions, then covered in ETFE fabric reinforced by a supporting cables system in stainless steel. The high complexity of the structure, made with variable radius arches, required the complete pre-assembly of all the 3 structures in workshop, ensuring the distances and the tight geometric tolerances required for the installation of the ETFE panels.
