Abstract: A device includes an assembly of conveying modules (3). Each of the conveying modules (3) is made up of a frame (1), a continuous handling conveyor, height and inclination adjusting element (18) and (2), and mechanical and electrical linking element (8) and (13) enabling the different modules to be linked so as to form a route capable of causing the transported loads to follow straight and/or curved trajectories with adjustable inclination.
