In order to ensure that the weight of the lifted material is evenly distributed to each electromagnet, the following structure is adopted in the whole electromagnetic lifting industry at present. The method comprises the following steps that a plurality of disc springs are uniformly arranged on a cross beam, an electromagnet is arranged below each disc spring, then the cross beam is lifted to the position above an area where a lifted material is located by a crane and then is put down, when the cross beam is completely put down, each disc spring is not stressed to be in a free state, and the lower surface of each electromagnet is in area contact with the sucked and lifted surface of the lifted material as much as possible; when each electromagnet is electrified to lift the material, if the surface of the lifted material is uneven, the electromagnets have different heights, so that the deformation quantity of each disc spring is different, and the gravity born by each electromagnet is different. That is to say, the gravity of the material is not evenly distributed to each electromagnet, the larger the gravity borne by the electromagnet at the lowest position is, so that the electromagnet is most likely to exceed the electromagnetic attraction limit of the electromagnet to be separated from the surface of the material, and after the electromagnet is separated, the gravity borne by other electromagnets is also increased sharply, and in serious cases, a serious accident that the whole material falls off occurs. Sometimes when the material with a smooth surface is hoisted, the material can also deform in the hoisting process, so that the deformation quantity of certain disc springs is different, and the material dropping effect can also occur.
