る。In the meantime, steel materials such as steel pipes and steel bars may be shipped in a plurality of bundles or a plurality of bundles at one time, or may be bundled into a single bundle and bundled for shipment. In other words, when loading these trucks, storing them on the sorting shelf of the warehouse, or taking them out, sometimes you want to suspend multiple or multiple bundles at once, if you want to select and suspend the number of bundles or the number of bundles, In some cases, it is desired to suspend one or a bundle from the middle of a group of steel materials in which steel materials are closely arranged.
However, a conventional lifting electromagnet having a plurality of excitation sections, as described above, exhibits an excellent function when suspending a plurality of bundles at a time or arbitrarily suspending the number of bundles or the number of bundles. Since the number of magnetic poles related to the excitation section is determined and the size is determined under the setting, the following defects existed when hanging a single pole or a single bundle. FIG. 6 shows an operation process when one or a bundle is suspended using the conventional lifting electromagnet 3. FIG. 5A shows a procedure in which when the steel material 4a located at the end of the arrangement of the steel materials is lifted, the steel material 4a is attracted to the magnetic pole at the end of the lifting electromagnet 3 and suspended. In addition, FIG.
Shows a procedure in which the steel material 4a is once drawn horizontally and then suspended by the magnetic poles of the appropriate excitation section of the electromagnet 3.

In addition, the magnetic pole on the unloading side of the lifting electromagnet may approach the adjacent piled steel material that is not to be handled and attract this steel material.Therefore, there is a problem that workers must be kept on site to avoid this. Was. In order to prevent this, it is conceivable to increase the clearance of the lifting electromagnet and widen the interval between the bundles of steel materials. However, in such a case, the storage efficiency of a warehouse or the like deteriorates. In addition, there is a problem that it is impossible to suspend an intermediate bundle from a group of steel materials in which various types of steel materials are mixed.
