Title:
METHOD AND APPARATUS FOR EXTRACTING AND INSTALLING HEAT EXCHANGER BUNDLES
Document Type and Number:
WIPO Patent Application WO2002027253
Kind Code:
A3
Abstract:
An apparatus and a method to remove and install horizontal heat exchanger bundles. A continuous track (32) and a main frame (12) having a carriage frame (28) with vertical hydraulic cylinders (26) are used and achieve the stability necessary to support and level heat exchanger bundle during removal from its shell at various vertical heights. The preferred configuration allows the main frame (12), hydraulic cylinders (26), pads (20) and tracks (32) which provide a large surface area on the ground, to remain on the ground as the hydraulic cylinders (26) raise the carriage frame (28) to the height of the bundle shell to increase stability of the apparatus (10). Moreover, the tracks (32) allow the self-propelled extractor (10) to move over gravel, asphalt, and/or soft uneven surfaces without becoming embedded into the surface. Alternatively, the carriage frame (28) may be raised or moved using a crane or helicopter by removing the carriage frame (28)from the main frame (12).
