Electromagnet for moving iron objects. It is formed with opposing magnetic heads (M<u1>u, M<u2>u), mounted at the ends of a carrying shaft (1), to which is also attached a steel cable (9). The electromagnet (M<u1>u, M<u2>u) can be raised and lowered with the help of the cable (9). By the magnetic heads (M<u1>u, M<u2>u) being attached to the shaft (1) by ball joints, a vertical line from a suspension point in a suspension means for the cable (9) carrying the electromagnet goes practically straight through the centre of gravity for the magnetic heads and the iron object to be lifted. A very safe lift is therefore obtained when lifting with the electromagnet. |
