Apparatus for moving a tube bundle out of or into a heat exchanger shell consists of an elongated frame structure including a pair of parallel spaced beams, a mobile carriage to support the tube bundle and mounted on the parallel beams for movement along them, clamps to connect and lock the elongated frame structure to the shell of the heat exchanger, a mobile sub-frame carrying a hydraulically-operated force-exerting mechanism to be connected to the tube bundle to move it out of the shell, and laterally positioned stops along the length of the frame structure to provide opposing thrust surfaces to the thrust exerted by the force-exerting mechanism so as to effect movement of the tube bundle along the frame structure. |
