Abstract: Apparatus for hydraulically extracting tubes from the tube sheets in condensers, heat exchangers and the like. The apparatus engages the interior wall of the tube being extracted with two complementary grabbing members. By relative translational motion, these grabbing members engage the entire circumference of the interior wall of the tube. The grabbing members are attached to a floating yoke that provides mechanical compensation for any misalignment between the grabbing members and the axis of the tube being pulled. The yoke also permits the grabbing members to be translationally adjusted by rotation with respect to the tube pulling apparatus. The yoke and the grabbing members are operatively connected to a friction carrier that limits the amount of relative translational motion between the members and thereby limits the lateral force exerted on the tube wall. The grabbing members, the yoke, and the friction carrier are connected to the operating shaft of a hydraulic cylinder that powers the apparatus.
