<P>PROBLEM TO BE SOLVED: To provide an electromagnetic lifting device that can facilitate maintenance at low cost and can stably be attracted. <P>SOLUTION: The electromagnetic lifting device includes: an electromagnet 1 where coils 3 are arranged around an outer circumference edge and that generates magnetic fields different in inner circumferences and outer circumferences of the coils 3; a metal protrusion 5 detachably attached to an attraction surface of the electromagnet 1 and functioning as a magnetic flux collecting body of a magnet of the electromagnet 1; a rotation/tilt axis 7 attached to a surface opposite to the attraction surface of the electromagnet 1 and suspending the electromagnet 1 rotatably so as to be tiltable; and a rotation/tilt restriction member 8 that restricts the range of the rotation/tilt of the rotation/tilt axis 7 and is connected and fixed to a driving device 9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
