Recently, QHMAG successfully won the bid for a steel plate lifting project of a top 500 Chinese machinery industry enterprise and a leading state-owned enterprise in the domestic lifting and transportation machinery field, thanks to its independently developed 20 ton electric permanent magnet lifting system. In this cooperation, Qianhao Magnetoelectric solved the problem of single lifting of ultra wide and ultra thick steel plates with excellent technical solutions, once again confirming its core advantages and industry benchmark position in the field of electro permanent magnet technology.

      Precise Tackling: Cracking the Pain Points of Oversized Steel Plate Lifting Industry

As a leading enterprise in the field of domestic lifting and transportation machinery, this state-owned enterprise has extremely strict requirements for the accuracy and safety of steel plate lifting equipment: it needs to achieve precise lifting of steel plates with a length of 4.5-20 meters, a width of 1.3-4.2 meters, and a thickness of 6-95 millimeters, especially in extreme working conditions with significant differences in length to thickness ratios. Traditional electromagnetic lifting equipment is prone to multi-layer adsorption due to uneven magnetic distribution, while permanent magnet lifting equipment is difficult to flexibly adjust the magnetic strength, and the industry has long faced the technical bottleneck of "large and difficult to refine".

      The QHMAG Team has innovatively proposed a combination scheme of "circular+elongated" electric permanent magnets through deep customized design

72 high-density circular electric permanent magnets: as the main adsorption unit, evenly distributed on the contact surface of the lifting device to ensure stable grasping of thin and small-sized steel plates;

28 group long strip electric permanent magnets: Specially optimized magnetic coverage of steel plates with excessive aspect ratios, achieved precise projection of magnetic lines through independent magnetic control technology, and eliminated the risk of multiple adsorption;

      More than 40 mechanical simulation verifications: Equipped with independently developed 20 ton high-strength crossbeams, after multiple rounds of structural optimization and fatigue testing, it perfectly matches the load curve of the crane and achieves industry-leading safety factors and dynamic response speed.
