Development of an overhead crane for remote handling tasks at nuclear facility

An overhead crane with telescopic motion was developed to transport servo-manipulator for remote handling tasks in the PyRoprocess Integrated inactive DEmonstration facility (PRIDE). The overhead crane consists of a telescope, trolley system, cabling management system, girder and rotation interface. The telescope of the overhead crane was designed as a cylindrical pipe-based tube type in order to increase the bending and twisting rigidity and it has a long extended length and short retracted length. The cabling management system was designed to be compact in size in order to accommodate the changed cable length according to the telescopic motion. All drive modules were designed to have spare modules in order to prepare for emergencies. As design verification process, structural analysis was performed on some important modules. Currently, the overhead crane is installed at a test bay in KAERI, and it is being tested.
