have been working at
a hydroelectric plant in
Portugal.
IC

T
ower crane manufacturer Linden
Comansa distributor in Portugal,
Ibergru, has supplied 15 flat top tower
cranes for the Baixo Sabor hydroelectric
plant project in Torre de Moncorvo.
The main contractor on the project is
Energias de Portugal (EDP), the largest
electricity utility company in the country.
Planning and logistics of the project have
been undertaken by Ibergru.
Two dams are being built at the site. The
main dam is upstream of the Sabor River,
while the second dam is 9.5 kilometres
downstream. The first hydroelectric plant
has a double-curvature dam with a height
of 123 metres and a width of 505 m. The
second plant, which is close to the river’s
mouth, will have a dam 45 m high and
315 m wide.
Around the site
To help with the large scale project, the 15
tower cranes have been located at different
sites. At the main plant, four model
10LC140 tower cranes with a load capacity
of 8 tonnes are being used.
Two of the 10LC140s have been used to
assist with the assembly of an air transport
system with cables to pour large amounts
of concrete during the construction of the
dams. The unusual cable crane system is
known as a blondin in honour of Charles
Blondin, a famous French tightrope walker
of the 19th Century.
Next to the upstream station, an LC5211
5 tonne tower crane is helping construct an
administration building, while two 5 tonne
capacity 5LC5010s are working as service
