The biggest construction site in Europe

Congested roads and metro lines: the “Grand Paris” project aims to prevent gridlock in the French capital. On construction sites across the city, Liebherr construction machines are helping pave the way to a modern Greater Paris Metropolitan Area.

A workplace with a view

From the cab of the 630 EC-H Litronic 70 metres up in the air, he enjoys a unique panoramic view. Crane driver Thomas Brun sees not only the Eiffel tower but his own neighbourhood. When the metro line that he is currently working on is finished, he plans to leave his car at home more often. “It’s great that I can play a part in modernizing my own neighbourhood,” says Brun.

A maximum of skill and experience

On the hook of his 630 EC-H 40 Litronic, with millimetre accuracy, Thomas Brun manoeuvres three arch bricks over the shaft, before lowering the 21 metric ton concrete load. His colleagues then load the components for the tunnel walls onto a train that rolls them into the tunnel shaft.

Everything gets used

The Grand Paris Express is expected to generate as much as 43 million metric tons of demolition waste. Part of this waste ends up at Paprec, a recycling company situated on a dock on the Seine, north-west of Paris. A mobile handling machine LH 24 M Industry Litronic is in use here.

Versatile in sustainability

“A lot is happening. The Grand Paris construction project is in full swing and all the demolition waste comes to us,” says Mouadni cheerfully, who operates the mobile material handling machine. But because the spoil heaps at Paprec are getting wider and higher by the day, they limit the space for manoeuvring. “This is where the new agile material handling machine really comes into its own”, says Mouadni.

Tours Duo

Not only the new metro lines but also new business centres will improve links between Paris and its suburbs. In the 13th district, for example, two skyscraper towers – “Tours Duo” – are being built. They will create a link between Paris and the commune Ivry-sur-Seine, and make the Greater Paris region even more attractive. On site is a HS 8050 HD duty cycle crawler crane, owned by construction firm Capocci.

A partner for Grand Paris

The “Tours Duo” construction site is typical for Grand Paris with confined spaces, a tight schedule, working restrictions and work running parallel. “To meet these challenges over the coming years, we are counting on our partner Liebherr,” says Asmâa Senhadji, Commercial Development Manager at Capocci.

Producing construction materials

A large project like Grand Paris requires enormous amounts of construction materials. Some of these materials are extracted in a limestone quarry by A2C granulat, using an R 970 SME Litronic crawler excavator. “The shovel of the R 970 SME is dimensioned to be able to accompany us throughout the development of the quarry”, says Romain Delhaye, Operations Manager at A2C Granulat.

Expert for loading

The material mined in the limestone quarry of A2C Granulat is loaded onto trucks and semi-trailers, which come by daily for new building material, with the L 586 XPower wheel loader.

25 metres below ground

Like a mole, the Liebherr LR 636 crawler loader is working relentlessly on the new metro line 15. “An underground project like this is a special challenge, even for us,” says Julien Wiame, construction supervisor at contracting firm Wiame TP. In the future, more than one million people from 22 districts will use the new metro line 15.

Working on the future

In a few years, thousands of people will pass by the place where this R 926 crawler excavator currently stands, on their way to work each day. “It makes us proud,” say construction supervisor Julien Wiame and site manager Jean-Paul Frade.

Living and working in the tightest spaces

In the east of Paris, surrounded by residential buildings, the new “Place Carnot” metro station is being constructed. Crane operator Ben Haddou and his colleagues work from 7 am to 11 pm. “We are considerate of our neighbours: the HS 8130 HD has very low noise emissions. Otherwise it would not be possible to work so late at night,” Haddou says.

Little space, lots of power

Ben Haddou and his colleagues are using the duty cycle crawler crane with slurry wall grab to construct the walls of the future metro station. These will extend to depths of up to 42 metres below ground. The benefits of the HS 8130 HD on this site are its compact dimensions, its 35-tonne winches and its lifting capacity of up to 130 tonnes, says Haddou.

A typical task

The individual components of a tunnel boring machine each weigh 295 metric tons. Here they are being lifted by an ?LG 1750 lattice boom mobile crane out of an excavation pit to the north of Paris. It is a routine task for the crane operator and the machine: “Assembling and dismantling tunnel boring machines will be one of the main uses for our Liebherr mobile cranes in the Greater Paris region over the next few years,” predicts Patrick Meublat, technical director of the crane business at Mediaco.
