る。2. Description of the Related Art Generally, a small-diameter long object such as a nuclear fuel rod used in a nuclear reactor (hereinafter simply referred to as a long object) has a length of about 1 cm inside.
It is a long and narrow tube with a length of about 4m and a diameter of about 1.2cm that accommodates a large number of pellets of about 1cm in diameter, and a relatively low rigidity of about 1mm in thickness. It is housed in several dozens at a time.

て受け台等に載置している。Conventionally, a long object of this kind has been taken out from a dedicated tray by a plurality of workers so as not to be damaged, and placed on a receiving stand or the like.

り、作業能率及び信頼性や安全性にも問題がある。However, since a plurality of workers manually handle the long object as described above, each worker grasps both ends of one long object and takes out the cradle. It is expected that this long object will bend in a bow shape and be in contact with the ground and cause damage when placed on the ground, etc., and careful attention will always be required, and the degree of fatigue of each worker will increase. There are also problems with efficiency, reliability and safety.

（特願平４−２３１６６号参照）。Therefore, as shown in FIGS. 11 and 12, a plurality of long objects 2 are horizontally arranged on a plurality of insole members 1 arranged at predetermined intervals, and are stacked in a plurality of stages. By holding the insole members in the tray 3 and holding the above-mentioned insole members with a gripping device and lifting them, the long object is held horizontally without bending, taken out of the tray without being damaged, and placed on the receiving table. Or transfer from a receiving tray to a tray has been proposed (see Japanese Patent Application No. 4-23166).

Since the insole is interposed between the long objects stacked on each other, the amount of storage is reduced by the thickness of the insole, and there is a problem that storage or movement efficiency is deteriorated. In addition, as described above, there is a problem that a dedicated tray for using the insole is required, and a large cost is required for manufacturing the tray and the insole.

用も低減できる等の効果を奏する。As described above, according to the present invention, an end holding jig is attached to the narrow end of the long object having the narrow end at one end, and the end holding jig is attached to the end holding jig. Lift one end of the long object by lifting the tool,
By moving the holding jig for removal inserted below the elongated object whose one end is lifted horizontally along the elongated object, the intermediate portion of the elongated object is sequentially moved upward, and the upward movement is performed. By sequentially inserting a plurality of intermediate support plates below the intermediate portion of the elongated object and moving it upward, the elongated object is held in a horizontal state. There is no need to use an insole between each step, so that the number of storage steps in the tray can be increased, and storage or movement efficiency can be improved. Moreover, there is no need for a dedicated tray for the use of the insole, and the effects of reducing costs for manufacturing the tray and the insole can be achieved.
