QP type grab electromagnetic double-girder bridge crane has both a grab and an electromagnetic sucker. The electromagnetic sucker mainly uses the electromagnetic principle to transport steel objects, and the main part is a magnet. When the current is turned on, the electromagnet will firmly attract the steel object and lift it to the designated place. Cut off the current, the magnetism disappears, and the steel item is put down. Electromagnetic cranes are very convenient to use, but they can only be used when there is current. They can be used in scrap steel recycling departments and steel making workshops.
The electromagnetic crane can generate a strong magnetic force, and dozens of tons of iron sheets, iron wires, iron nails, scrap iron and other iron materials can be easily collected and transported without packing, packing or bundling. The operation is labor-saving and the work is simplified. Steel materials and machines in wooden crates can be handled similarly. When the crane is working, as long as the current in the electromagnet coil does not stop, the heavy objects that are sucked up will not fall, and the invisible magnetic force is more reliable than a solid chain. If the power is cut off for some reason, the crane generally has a safety protection device and a battery, which can generally be maintained for about half an hour after the power failure, so as to avoid accidents such as power failures that cause the objects attached to the disk to fall and cause accidents. Cranes cannot handle hot iron, because hot steel cannot be magnetized.
The grab electromagnetic bridge crane is also equipped with a grab, which can be used to grab scraps and other objects. Therefore, this type of crane can meet the two work occasions of grabbing and adsorbing steel waste, and has a wide range of applications.
