Double girder electromagnetic overhead crane is a crane that uses magnet to carry steel products. Turn on the current, absorb the magnet steel items, and transport them to the designated location. When the current is cut off, the magne force disappears and the steel product falls. Magnetc cranes are very convenient to use, but must be used with electric current. It can be used in metallurgical plants or steel plants.
Double girder electromagnetic overhead crane with magnet is composed of beams, walking mechanism, lifting trolley, electrical parts and magnet spreaders. After the power is off, the magnet suction of the bridge crane can last for a minimum of 20 minutes. If you have requirements for the magnet retention time of the electromagnet, you can tell us in advance.
The shape of the magnet spreader can be customized according to the size of the material to be lifted, such as round, square, and rectangular. There are two types of magnet double girder overhead cranes: magnet chuck and magnet beam. Magnet beams can also be divided into two types: non-rotating beams (vertical or parallel to the main beam) and rotating beams (upper beam or suspended beam).
Double girder electromagnetic overhead crane can generate strong magnetic field force. Steel billets, steel coils, steel bars, scrap iron and various other iron materials weighing tens of tons are very convenient for handling and storage. It not only saves labor, but also improves work efficiency. When the crane is working, as long as the current in the solenoid coil keeps on, the lifted heavy objects will not fall. If the power is cut off for some reason, the magnet suction can last for at least 20 minutes. If the temperature of the iron material you hoist is high, please explain to us in advance the temperature of the iron material that the magnet needs to hoist.

How to select the suitable Electromagnet crane
1) lifting Capacity. It is the maximum weight of the lifting goods.
2）Lifting height: The lifting height of the goods expeact the height of the electromagnet .
3）The size of the lifting goods, such as length,wide , height , diameter or others.
4）Do you need trolley rotation or electromagnet rotation?
5）The temperature of the lifting goods. If the temperature of the lifting goods is not the ambient temperature, In order to send the crane fully meet your use, please share the maximun temperature of the lifting goods.
