METHOD OF FASTENING HOISTING MAGNETS TO CROSSPIECE IN REMOVABLE GRIPPER DEVICE Russian patent published in 2016 - IPC B66C1/06 

FIELD: instrument making.

SUBSTANCE: invention relates to removable lifting devices and can be used as part of any lifting means for lifting freight tonnage lengthy ferromagnetic, for example, for lifting and moving metal sheets 12,300 mm long, 4,500 mm wide and 27 mm thick, i.e. goods which, by virtue of those or other reasons, can not be moved with use of conventional flexible lines. Technical result of present utility model is to improve reliability of retention by providing a uniform load on lifting magnets. Removable load handling device which realises proposed method is designed as a yoke 1 (fig. 3 shows only part of traverse, which is fastened to spring) and lifting magnets 2, 3, 4, 5 and 6 attached to cross member 1 through respective springs (spring blocks) 7, 8, 9, 10 and 11.

EFFECT: use of springs (spring blocks) 7-11 ensures redistribution (alignment) of loads on lifting magnets 2-6, which enhances reliability of retention.
