  • Patent number: 8261514
    Abstract: An apparatus and method for loading drums into a drum container, in which a function of gripping a lid of the drum container is added to a gripper used when a drum filled with radioactive waste is loaded into the drum container, thereby considerably reducing loading time of the drums, risk of dropping the drum, and preventing a radiation exposure risk. The apparatus includes a drum feeder transferring a drum, a drum container into which the drums transferred through the drum feeder are sequentially loaded, a support frame on which a lid of the drum container is placed when the drums are being loaded, and a crane having a gripper that selectively grips and transfers the drum or the drum container lid. The gripper includes radial gripper arms, an arm hydraulic unit reciprocating the gripper arms, jaws on inner sides of the gripper arms and gripping an outer surface of the drum, and latches for latching the drum container lid.

  • Patent number: 8250836
    Abstract: An apparatus and method for automatically loading drums into a drum container, in which, when the drums filled with radioactive waste are loaded into the drum container, the drums are fed to a designated position, and placed at a fixed position, reducing loading time and manpower as well as minimizing radiation exposure risk associated with radioactive waste treatment. The apparatus includes a drum feeder having conveyor modules transferring the drums and a turntable rotating a drum transferred to an orientation where the drum can be gripped, for sequentially loading the drums, a support frame on which a lid of the drum container is placed when the drums are being loaded, and a crane that grips and transfers the drum or the drum container lid.
