Section: summary

The guiding masts grippers of core reactor charging machines have heretofore been designed as grate constructions or as round tubular masts or posts. Designs of this type have the drawback that the guiding means for the grippers which guiding means are arranged within the interior of the guiding mast can be post-set only under difficulties by means of special tools. Therefore, a post-setting of the production means is frequently omitted. Furthermore, the design of such guiding masts in the form of grate constructions requires many parts and is expensive. As to the round pipe construction, the procurement of the pipes, which necessarily have to consist of special steel, with the respective required pipe diameters is rather difficult because the required pipe diameters frequently deviate from the listed diameters of the commercially available special steel pipes. Moreover, with round pipes, the introduction of the guiding means is possible only by means of expensive auxiliary constructions which additionally are not easily accessible and can hardly be controlled optically. It is, therefore, an object of the present invention to provide guiding masts for grippers of core reactor charging devices which can be so designed that they can be economically manufactured and that the manufacturing means for the grippers can easily be post-adjusted and checked.
