Electromagnetic crane is to use the principle of electromagnetic steel article handling machine. The main part of the electromagnetic magnet crane. Making current, the electromagnet put steel items firmly suck, lifted onto a designated place. Cut off the current, the magnetic disappear, steel items will come down. Electromagnetic crane is easy to use, but there must be current before you can use that can be applied in the waste recycling sector steel and steelmaking workshop.
Use electromagnets to carry the electromagnetic device called Steel crane. Electromagnetic crane can produce a strong magnetic field strength, dozens of tons of iron, wire, nails, scrap iron and various other materials, without packing no packing strapping do not, you can easily collect and transport, not only operation and effort, and the work simplified. Mounted in a wooden box of steel materials and machinery can be equally handling. Crane work, as long as the current in the electromagnet coil constantly being sucked up heavy objects will not fall, the invisible magnetic force is more reliable than the sturdy chain. If for some reason cut off electricity, it will cause an accident, so some electromagnetic crane is equipped with a steel claw, lift heavy objects to be transported, the sturdy steel claw will automatically fall firmly fastened them. Cranes can not carry hot iron, because the heat of the steel can not be magnetized. Large electromagnetic crane can lift hundreds of tons of heavy objects at once, the figure of the electromagnet diameter of about 1.5 meters, lift 16 tons objects.
February 21, 2008 Administration of Quality Supervision, Inspection and Quarantine promulgated the "Lifting Safety Technology Supervision - bridge crane" Article 66 shall electromagnetic crane lifting electromagnet powered by a dedicated circuit. Electromagnetic crane work due to loss of power, and its lifting objects fall may cause harm, it must be able to guarantee electromagnetic chuck power supply.
