The technical problem to be solved by the present invention is that of providing an apparatus allowing to overcome the drawbacks hereto mentioned with reference to the known art. The beam supports a movable carriage which is connected to the separable tube bundle and through which force can be exerted upon the tube bundle to extract it from or insert it into its shell. Each element 86 supports a respective transverse pin 88 upon which is pivotally mounted a clevis 90 to which is rigidly afiixed a respective connector pin 2. Thus the forces acting on the long shaft member 5% are always tension forces regardless of the direction of movement of the tube bundle. Since this is often done during a turnaround or shut down it needs to be done quickly and efficiently to minimize the amount of downtime required. Like any mechanical innovation, it has undergone subtle, but significant, improvements in its performance and adaptability over time.
