ABSTRACT:
A yoke-like attachment assembly for connecting a lifting hook with a lid portion of a nuclear reactor pressure vessel or the like, comprising a plurality of separate coupling assemblies extending parallel to each other between the lifting hook and lid, wherein each coupling assembly is capable of supporting the entire weight of the lid in the event of the failure of the remaining coupling assembly. Each coupling assembly includes a pair of spaced sheet-metal lugs, each mounted on a support plate assembly, with at least one bolt interconnecting the spaced lugs with the lifting hook positioned therebetween. Each support plate assembly is attached to a separate beam which, in turn, is attached to the lid.
