Development of a bridge transport system with telescopic motion

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