Mobile gantry crane at the Guiana Space Center

As part of the Ariane 6 program, CNES was looking for a strong industrial partner to manufacture a mobile gantry crane for the launch base at the Guiana Space Center (CSG), in line with technical operational requirements.  

The mobile gantry enables : 

  • verticalization and positioning of the launcher on its launch pad 
  • hoisting the satellite fairing 
  • configuration of the launcher prior to lift-off
