Abstract: A vehicle for transporting boxes in a loading volume, the boxes being stacked on at least one trolley with wheels, engaging with at least one guide rail attached to the floor to guide the movement of said trolley. The vehicle has at least one device exerting a horizontal force on a row of boxes placed on at least one trolley to move them towards an opening of the vehicle. The vehicle furthermore has at least one roof bar holding, at the upper portion, at least one stack of boxes placed on a trolley. The presence of a roof bar ensures that the boxes are properly held in the loading volume, thus preventing breakage during transportation.
