ABSTRACT:
A handling tool for selectively removable cruciforms employed in ice baskets of the type employed with nuclear power generator systems. The tool includes clamping means for engaging a compressible central portion of the removable cruciform to retract same inwardly and permit moving same, in a horizontal orientation, throughout the axial height of the interior of the ice basket. When at a desired elevation, selective actuating means moves previously retracted guide means to an extended or projected position for engaging a retaining ring of the ice basket and supporting the tool on the ring. The clamping means is selectively actuated to the disengaged position for releasing the cruciform whereupon the same expands, projecting legs associated therewith radially outwardly and engaging the retaining ring, to support the cruciform on the ring. The tool may thereafter be removed. For removing a cruciform, the tool is lowered and the clamping means actuated to engage and compress the central portion thereof for releasing these from the ring and, in that condition, is raised for removing the cruciform from the ice basket.
