3. Selection criteria

The choice of equipment must be the result of a study that takes into account :

• load constraints ;

• environmental constraints ;

• operating procedures ;

• constraints linked to the technology of the various devices.

• Load constraints

  Here are the main parameters to consider:

  • Weight: in order to determine the FEM group of the bridge, the weight of the various loads to be handled by the bridge must be clearly defined, in order to define the load condition;

  • volume: the shape of the part must be carefully examined, as it can have major consequences for the choice of equipment, and may...
