A reusable up-ending device for loading or unloading nuclear fuel assembly shipping packages. The device has a translating base mounted to a fixed beam structure and two stabilizing arms affixed to a mounting fixture on the base that is secured to the operating floor. The stabilizing arms include a spring dampener and have a simple elbow joint that straightens after the package is up righted. Translation is achieved by means of a hand adjustable lead screw and enables the base to be most advantageously positioned. The shipping package is inserted into pivot mount blocks located at the front of the base and the package is secured at the pivot mount blocks by means of a trunnion and at the support arms by means of a locking pin. Once the package is up-righted the elbows on the support arms are locked in place.
