<p>It comprises a rotatable and retractable storage lug (50) equipped with a rotatable and slidable weight-cylinder assembly (76 and 64) in coaxial relationship with a pivoted support beam (60). The weight-cylinder assembly (76 and 64) and support beam (60) are connected together by a lockable channel (70 and 70A), groove (68 and 68A) and pin (62 and 62A) arrangement. By rotating the cylinder (64), the support beam (60) will assume either a horizontal or working position or a vertical or stored position. A plurality of the lugs (50) may be affixed, for example, to an indexing fixture (40) to enable the fixture to be stored on a plenum assembly (16) of a nuclear reactor to reduce floor storage space requirements and downtime when the reactor is disassembled for refuelling, internal inspection and/or maintenance.</p> |
