The Sarens company recently assisted the roof extension of the Anoeta football stadium in San Sebastian, Spain, for the joint venture client Anoeta Envolvente, composed of Altuna y Uria and Construcciones Moyua. For Sarens, the task consisted in performing tandem lifts of four new steel truss girders of 400t and 156m long. The company also lifted four smaller trusses. For these several operations, two Demag Superlift 3800 lattice boom crawler cranes in SWSL configuration has been used, which could bear 201t with a maximum radius of 54m.
“The crane’s main parts were transported by sea vessel and delivered to a harbour near the work site. Then, up to 100 trucks delivered the equipment to the stadium, located in the middle of the city,” as stated the Belgian firm. On site, ten days were required to install and rig each cranes, working mainly by night in order to not disturb other subcontractors and local city transport. Four crew members worked together for each operation for the tandem lifting of the steel girders.
