Heat exchanger bundle extractor

A heat exchanger bundle extractor apparatus (1), comprises:

• a supporting base (2,29,40), onto which a hoisting column (6) is rotatably mounted, said supporting base comprising means (16) for rotating said hoisting column (6) on its own vertical axis;
• a guide frame (7), mounted onto supports (8) on the hoisting column (6), and controlled hoisting and lowering means (9) for the moving of said supports (8) and said guide frame (7) along said hoisting column (6);
• a push/pull device (14) suitable for coupling to a respective front flange of a bundle, mounted on said guide frame (7);
• longitudinal translation means (15) apt to longitudinally moving said guide frame (7) with respect to said supports (8), said guide frame (7) being provided with sliding supporting surfaces (25) for said bundle;
• and
• transversal translation means (19) mounted at said supports (8) and apt to transversally move said guide frame (7) with respect to said supports (8) and to the hoisting column (6),
• wherein said supporting base (2,29,40) comprises a multiplicity of hydraulic jacks (5, 5′) mounted onto telescopic supports (50) horizontally movable with respect to the plane of said base (2,29,40), and wherein at least a part of said multiplicity of hydraulic jacks (5′) comprises powered wheels (51) for the moving of said base.
