This Standard covers underhung cranes, top-running bridge and gantry cranes with underhung trolleys, traveling wall cranes, jib cranes, monorail systems, overhead hoists, and hoists with integral trolleys used in nuclear facilities. Nuclear facilities can include nuclear power plants (NPP), small modular reactors (SMR), and advanced reactors. All of the above cranes, whether single or multiple girder, are covered by this Standard with the exception of multiple girder cranes with both top-running bridge and trolley, which are covered by ASME NOG-1.
