A transport device for transport a container element for receiving and transferring articles, characterised in that it comprises: a support element fixable to the container element, and predisposed to be constrained to a movement organ for moving the container element, at least a carriage, fixed to the support element, a pair of internal wheels and a pair of external wheels predisposed on the carriage so that between the pair of internal wheels and the pair of external wheels there is space necessary for them to be able to engage with a guide rail and roll slidingly on the guide rail, for guided transport of the container element when it is set in motion by the relative movement organ, and in that: the pair of internal wheels are rotatably mounted on relative pins which are predisposed on the carriage by means of an elastic coupling so that the position of the relative axes can be elastically yielding so that the interaxis between the pins can vary as a consequence of stresses to which the pair of internal wheels can be subjected during running thereof along the guide rail, caused by a change of direction of the guide rail, the pair of external wheels are rotatably mounted on relative pins which are predisposed on the carriage by means of an elastic coupling so that the position of the relative axes can be elastically yielding so that the interaxis between the pins can vary as a consequence of stresses to which the pair of external wheels can be subjected during running thereof along the guide rail caused by a change of direction of the guide rail. a support element fixable to the container element, and predisposed to be constrained to a movement organ for moving the container element, at least a carriage, fixed to the support element, a pair of internal wheels and a pair of external wheels predisposed on the carriage so that between the pair of internal wheels and the pair of external wheels there is space necessary for them to be able to engage with a guide rail and roll slidingly on the guide rail, for guided transport of the container element when it is set in motion by the relative movement organ, and in that: the pair of internal wheels are rotatably mounted on relative pins which are predisposed on the carriage by means of an elastic coupling so that the position of the relative axes can be elastically yielding so that the interaxis between the pins can vary as a consequence of stresses to which the pair of internal wheels can be subjected during running thereof along the guide rail, caused by a change of direction of the guide rail, the pair of external wheels are rotatably mounted on relative pins which are predisposed on the carriage by means of an elastic coupling so that the position of the relative axes can be elastically yielding so that the interaxis between the pins can vary as a consequence of stresses to which the pair of external wheels can be subjected during running thereof along the guide rail caused by a change of direction of the guide rail. the pair of internal wheels are rotatably mounted on relative pins which are predisposed on the carriage by means of an elastic coupling so that the position of the relative axes can be elastically yielding so that the interaxis between the pins can vary as a consequence of stresses to which the pair of internal wheels can be subjected during running thereof along the guide rail, caused by a change of direction of the guide rail, the pair of external wheels are rotatably mounted on relative pins which are predisposed on the carriage by means of an elastic coupling so that the position of the relative axes can be elastically yielding so that the interaxis between the pins can vary as a consequence of stresses to which the pair of external wheels can be subjected during running thereof along the guide rail caused by a change of direction of the guide rail.
