DescriptionAEC-70-8684 A MECHANICAL GRAB "FISHING" TOOL, conceived and designed by the AEC's Nevada Operations Office staff, has taken some of the tedium out of recovering "lost" equipment from the deep holes drilled for underground nuclear tests. The tool was fabricated for the AEC by Drilco, Inc. (Odessa, Tex.). Weighing 53,000 pounds, the grab is shown being picked up with a crane before being placed into position under the drill rig floor to be lowered into a 120-inch diameter hole. The tool is lowered into the hole on drill pipe and is closed by the screw being rotated by the drill pipe at the surface with the drill rig. Credit: USAEC, Nevada Operations Office
