ヤンネルボツクス取扱具では、貯蔵ラツク９が障
害となり取扱えないという欠点がある。 However, as the number of used channel boxes is increasing due to the active operation of nuclear power plants, it is not desirable to use adapters to store channel boxes. Therefore,
As shown in FIG. 6, a method of storing without using an adapter is being adopted, but in this case, there is a drawback that the storage rack 9 becomes an obstacle and cannot be handled with conventional channel box handling tools.
本発明は、上述の事情に鑑みてなされたもの

とができる。 The channel box handling tool 12 lifted by the fuel exchanger auxiliary hoist etc. is attached to the main body frame 1.
The stopper 18 of No. 3 hits the clip 8 of the channel box 7, and the wire rope 19 is inserted downward until it becomes slack. From this state, the cylinder 14 is operated to push the actuator 15 downward. The actuator 15 is provided with a groove 20 inclined to the axis in which a guide 19 fixed to the pawl 16 slides, and the pawl 16 slides to the position indicated by the two-dot chain line using the pin 21 as a fulcrum. The hoist is then hoisted so that the claws 16 can grip the clip 8 and lift it for handling.
