AN APPARATUS FOR PULLING UP MULTIPLE STUD TENSIONER

摘要

PURPOSE: A multiple stud tensioner salvaging apparatus is provided to combine all stud bolts and nuts of a nuclear reactor head at the same time through a single lifting operation, thereby reducing time and manpower required for combining the nuclear reactor head. CONSTITUTION: A multiple stud tensioner(200) is used for combining a stud bolt(130) of a nuclear reactor(100). The upper end of a lifting module(410) is combined in a crane(300). The lifting module comprises three arms extended in a radial shape in order to maintain an angle of 120 degrees from each other. One end of a tie rod module(420) is extended to a lower side in the end part of the arm. The other end of the tie rod module is combined with the multiple stud tensioner. A control module(430) automatically or manually controls the tie rod module and lifting module.
