  • Fabricated electric lifting magnet
    Patent number: 5748062
    Abstract: An electric lifting magnet includes a casing that is fabricated entirely from components such as, for example, structural steel that are welded together. In particular, the lifting magnet includes a flat top plate that is stiffened and supported by a frame that is welded to the top plate. The frame includes a plurality of stiffeners that extend from the center of the top plate to the radially outer edges of the top plate, the stiffeners being welded together at the center of the top plate. The stiffeners are shaped and arranged on the top plate so that the frame that they form can bear the entire load that the lifting magnet is designed to withstand.
