Abstract

The present invention relates to relative positioning of land vehicles in relation to a crane, for unloading and loading a load respectively from and onto said vehicles. The invention relates to a method in which a first vehicle is positioned under said crane, characterized in that at least one second vehicle detects the position of the first vehicle in order to position itself in relation thereto.

Claims

1. A method for relative positioning of land vehicles in relation to a crane for loading and unloading a load respectively onto and from said vehicles, in which a first vehicle is positioned under said crane, characterized in that at least one second vehicle detects the position of the first vehicle in order to position itself in relation thereto.

3. The relative positioning method as claimed in claim 1, characterized in that the positioning of said second vehicle is performed while the first vehicle is moving.

4. The relative positioning method as claimed in claim 1, characterized in that the positioning of the first vehicle under the crane is performed in relation to a global coordinate system centered under said crane or through guidance information transmitted from said crane.

5. The relative positioning method as claimed in claim 1, characterized in that it consists in calculating the differentials of coordinates, according to at least two axes, of the positions between the first and the second vehicles, then, according to said differentials, transmitting guidance indications to said second vehicle.

6. The relative positioning method as claimed in claim 5, characterized in that a degree of tolerance is applied to said differentials

2. The relative positioning method as claimed in claim 7, characterized in that the positioning of the vehicles is performed in real time.
