Hoisting Ropes

Millau Viaduct

Manitowoc use Notor HP for the Millau Viaduct

The Millau Viaduct is a cable-stayed bridge that spans the gorge valley of the Tarn near Millau in southern France. It is one of the tallest bridges in the world, with one mast’s summit at 343 metres above the base of the structure. In a French-British partnership, it was designed by the English architect Sir Norman Foster and French structural engineer Michel Virlogeux, and as of May 2017 it is the twenty-second highest bridge deck in the world, being 270 metres between the road deck and the ground below.

The bridge was constructed using 7 Manitowoc K5/50 C cranes (one crane per pile) with a hook height of 95.5 to 264.4 metres. More than 1000 metres of Notor HP were used for the construction.

 

Nuclear power station construction, Turkey

Nuclear power station construction, Turkey

The high anchor crane used for the construction of this nuclear power station in Turkey was installed in the centre of where the chimney was to be built. With a requirement for the crane boom to turn through 360° throughout the construction process, it was necessary to stabilise the crane with COMPLAST 9 Ø26mm linking the crane tower to the chimney structure. As the built structure increased in height, the stabilising ropes were raised through a system of pneumatics.

NOTOR HP Ø16mm was used for main hoist up to 160 metres.

 

Hoisting ropes for Sagrada Família, Barcelona, Spain

Sagrada Família, Barcelona, Spain

The Basílica i Temple Expiatori de la Sagrada Família is the renowned unfinished Roman Catholic Church in Barcelona, designed by Catalan architect Antoni Gaudí.

First started in 1883, Gaudí’s work on the building is part of a UNESCO World Heritage Site. Relying solely on private donations, the completion of the Sagrada Familía is a long and slow process.

Manitowoc MD560B cranes, used in the ongoing construction of the church, were equipped with NRHD 24 Ø20mm.

Some of the project’s greatest challenges remain, including the construction of further spires. It is anticipated that the building will be completed by 2026 - the centenary of Antoni Gaudí’s death.
