The main part of the electromagnetic overhead crane is magnet and it carries steel items through electromagnetic principle. Making current, the electromagnet will catch up the steel material tightly and carry them to the pointed place; Breaking current, the electromagnet will disappear and then put the steel material down. The electromagnetic crane can produce powerful magnetic field force, it can carry dozens of tons of sheet iron, iron wire, iron nails, waste iron and other different kinds of iron material easily, all of them need not packaging and can be collected and carrying easily. It not only easy operating, but also simplify the work. It can also carry steel material and Roberts packaged in boxes. As long as there is current in magnet coil, the catching items would not down, the invisible magnetic force is much stronger than strong chains. If the current stooped, the steel talons on the crane will catch theses items tightly to avoid accident. The electromagnetic overhead crane cannot carry hot iron because the hot iron cannot be magnetized. The electromagnetic overhead crane can be used in wasted steel recycling sector and steel shop.
