QA electromagnetic double beam bridge crane

       QA type universal bridge crane, crane, driving, (electromagnetic) overhead crane, driving, with removable electric disk, especially suitable for metallurgical factories in indoor or open-air fixed spans Black metal products and materials. In machinery factories, warehouses are also commonly used to transport steel, iron scrap and other materials.

       This machine is composed of five parts: a box bridge, a vehicle running mechanism, a trolley, a grab, and an electrical equipment. All the mechanisms are operated in the control room. When using in the open air, it must be equipped with rainproof equipment.

       A machine that uses electromagnetic principles to move steel objects. The main part of an electromagnetic crane is a magnet. When the current is turned on, the electromagnet holds the steel objects and lifts them to the designated place. When the current is cut off, the magnetism disappears and the steel items are put down. The use of electromagnetic cranes is very convenient, but the current can be used only when it is used. It can be applied to the scrap steel recovery department and the steel-making workshop.

       A device that uses an electromagnet to transport steel materials is called an electromagnetic crane. Electromagnetic cranes can produce powerful magnetic force, dozens of tons of iron pieces, iron wires, nails, scrap iron and other kinds of iron materials. They can be easily collected and transported without packing, packing or bundling. Operation is labor-saving and work is simplified. The steel materials and machines installed in the wooden box can be handled in the same way. When the crane is working, as long as the current in the coil of the electromagnet does not stop, the sucked up weight will not fall, and the invisible magnetic force is more reliable than the firm chain. If the electricity is cut off for some reason, it will cause an accident. Therefore, some of the electromagnetic cranes are equipped with steel claws. After the heavy objects to be transported are lifted, the solid steel claws will automatically fall and tightly buckle them. Cranes cannot carry hot iron because high temperature steel cannot be magnetized. The large electromagnetic crane can lift nearly 100 tons of weights at once. The electromagnet in the figure is about 1.5 meters in diameter and can lift 16 tons of objects.

       On February 21st, 2008, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China promulgated Article 66 of the "Safety Supervision Regulations for Hoisting Machinery - Bridge Cranes". The lifting electromagnets of electromagnetic cranes should be powered by dedicated circuits. When electromagnetic cranes are working, they may be able to ensure the power supply of the electromagnetic chuck when they fall down and may cause harm.
