ABSTRACT:
A crane for use in a nuclear waste handling facility is disclosed. The crane includes a bridge of sufficient transverse dimension to span the width of the area being serviced, a bridge drive for moving the bridge along spaced rails extending longitudinally along opposite sides of the area being serviced, and a crane control cabinet depending from a cantilevered support extending from one end of the bridge. The nuclear waste handling facility includes a stationary radiation barrier extending longitudinally in spaced relationship to one of the rails supporting the crane. The barrier is positioned between the bridge and the crane control cabinet. The disclosure also covers a crane that includes a bridge of sufficient transverse dimension to span the width of the area being serviced, the bridge including at least one horizontally elongated girder with an enclosed interior space having a cross-section of sufficient dimension to permit access to the interior space by operating personnel, the girder including a modular radiation barrier within its interior and a crane control facility within its interior. In a preferred embodiment, the crane has a trolley mounted on the bridge which is adapted for horizontal travel along the bridge and has a hoisting mechanism mounted on it. Advantageously, the bridge drive includes separate primary, secondary and teritiary drive mechanisms. The bridge and trolley are constructed to minimize the height of the trolley above the bridge and the width of the bridge.
