Abstract

An apparatus for transporting and inverting core frame parts of a nuclear reactor includes a cross beam. A horizontal shaft is supported on the cross beam. A flexion and torsion-resistant basket is disposed below the cross beam for receiving a core frame part. A bearing pivotably supports the basket on the horizontal shaft. Pulleys are attached to opposite sides of the basket at right angles relative to the shaft. Positioning drives are seated at the cross beam and deflection rollers are adjustably attached to the positioning drives. Flexible tension members each lead from a respective one of the pulleys to a respective one of the positioning drives and to a respective one of the deflection rollers. The tension members are prestressed relative to the bearing for the basket.
