METHOD AND APPARATUS FOR EXTRACTING AND INSTALLING HEAT EXCHANGER BUNDLES

WIPO Patent Application WO2004010069

A3

An apparatus (50) and a method to remove and install heat exchanger bundles (195). The apparatus (50) comprises a main frame (12) supporting wheel assemblies (32). A lifting system (18) is provided which elevates the entire unit so that the wheel assemblies (32) are off the ground a minimal distance to ensure stability and then the second frame (28) is elevated the remaining amount to the final elevation of the heat exchanger bundle to be removed or installed. The preferred embodiment includes a horizontally displaceable portion (80) of the second frame (28) for supporting the heat exchanger as it is extracted from the shell side assembly (300). The unit is self-contained including power means (78) to horizontally displace the frame (12) to affect the displacement of the heat exchanger, lower the second frame (28) relative to the main frame (12), and then lower the entire unit to the ground. The unit is also powered so that the wheel assemblies (32) which are individually steerable can maneuver the unit into a restricted area.
