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.

Large quantities of construction waste

The construction waste that is removed on numerous construction sites, must be transported out of the city. The company Cemex takes care of this with 12 Liebherr mobile material handling machines. The material is transported by truck to several locations within the city where it is loaded onto ships that transport it to quarries or recycling plants.


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.


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.

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.


Specially for this application

Only 30 kilometers away from this construction site are other ENCO workers using Liebherr machinery in operation for Grand Paris. "The sticks and booms of the machines have been specially adapted for this job so we can dig extra-large trenches," says operator Paulo Vieira Lopes, who controls the R 926 crawler excavator expertly.


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.


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.


Utmost precision

Just five minutes from the Arc de Triomphe the RER E train line is being extended as far as the metro station Porte Maillot. On site are an HS 8100 HD duty cycle crawler crane, and an LR 1160 crawler crane. “Two other metro tunnels are located right next to our tunnel – so maximum precision is called for,” says François Gravoille, site manager at VSL Infraror.


Improved safety

On the restricted jobsite, the crawler crane’s adaptive lighting and precise control are an advantage. “That means improved safety,” says crane operator Jacky Dupré.

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.


Up to 55 metres deep

At a construction site outside the center of Paris, ENCO uses several Liebherr machines. Two crawler excavators R 946 and R 944 and a crawler loader LR 634 are in operation to build a new metro station of line 15. Operator Antonio De Sousa raises earth from a depth of 22 meters with the R 946. "The crawler excavator could even grab 55 metres deep and has an enormous flow rate“, says De Sousa. On an eight-hour working day, his machine and he transport around 700 cubic metres of earth to daylight.


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.


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.
