We’ve equipped the eight tower cranes at the Aulnay-sous-Bois site: five Wolff 7534.16 and three Potain MDT 308 cranes, which are working on the construction of the operations center for lines 16 and 17 of the Grand Paris Express.
In Aulnay-sous-Bois (near Paris), for the past few weeks five Wolff 7534.16 as well as three MDT 308 have been erected for the construction of the operating center for subway lines 16 and 17 of the « Grand Paris Express ».
After a year of excavation and servicing of the site's platforms, the tower cranes were installed and equipped with anti-collision and zoning systems, DCS 61-S. In total, 8 tower cranes, including 1 in travelling, will be necessary for the simultaneous construction of 11 buildings on an area of 20 hectares within 32 months. For this large project, up to 400 workers will be mobilized during peak periods.
In order to keep rate of work and deliver the project for 2024, high lifting capacity machines were chosen. The companies involved in this extraordinary project have particularly high requirements in terms of productivity and reliability. Ensuring safety and meeting deadlines are the key words in « Grand Paris »!
To go fast it is therefore necessary to ensure the productivity of the site and consequently of the cranes. DCS 61-S systems meet these needs by detecting in real time the risk of collision of interfering cranes or the risk of entering a predefined prohibited area.
The DCS 61-S intervenes on the crane control mechanisms to slow down and then completely immobilize the crane at a pre-set distance from the obstacle if a risk of collision is detected. In addition, crane operators have access to all the information they need in real time, thanks to the screen placed in their cab. This nerve center of future lines 16 and 17 of the « Grand Paris Express » (GPE) will consist of:
- a centralized command post (PCC), responsible for collecting all the data from lines 16 and 17 in real time, coordinating train traffic, and monitoring and regulating traffic.
- the maintenance and storage site (SMR), where the trains will be received, checked, maintained, repaired and stored.
- the infrastructure maintenance site (SMI), to guarantee the operating condition of metro equipment (rails, engineering structures, energy distribution, etc.).
