ABSTRACT:
Tube bundles of heat exchangers are pulled and replaced by an apparatus that butts against the shell of the heat exchanger and draws out the tube bundles lengthwise. The device may be moved by a crane, and for this purpose has a single suspension point which can be moved lengthwise according to the altered position of the center of gravity depending on whether a tube bundle is supported thereon. A fixed support with a vertically movable cradle is provided adjacent the heat exchange casing and a horizontally movable support with a vertically movable cradle is provided remote from the casing, for supporting the tube bundle.
