The cranes, with maximum loads between 5 and 48t, are working on the construction of a range of different facilities at the dam.
The main plant, located upstream, is a double-curvature dam and will have a height of 123m and a width of 505m. It is being built using four 8t. The assembliy of two of these 10LC140 cranes was a challenge due to the difficult accessibility. In order to bring the cranes to the site large amounts of concrete were supplied, using an air transport system with cables already on the project.
Next to the upstream station, a LC5211 5t tower crane has been constructing a building that will be part of the administrative facilities of the dam. Two 5t 5LC5010’s act as service cranes in the yards that serve as warehouse and workshop of the jobsite materials.
The secondary plant, of gravity type, is located downstream closer to the river’s mouth. The five largest tower cranes working in this project are: two 48t 21LC750’s and three 18t 21LC550’s. A 5t 5LC5010 is working as a service crane, helping to manage the machinery and materials required on the site.
In addition, two Linden Comansa 18t 21LC290 cranes are working on the construction of a new 268m long and 40m high bridge. Located near the downstream plant, this bridge will allow the EN102 road to cross the river, since the current Portela Bridge will be submerged by the waters.
