This series which adopts "n" type of magnetic circuit and double wrapping has good advantages in heat dispersion, penetration,(for example it can penetrate air gap through multiple layers) and can lift and transport bar material, flat iron and angle iron in unpacked or simple packed situation. There are two kinds normal & high temperature type. Normally multiple units are used in operation, so two or four connection points are used lo『 linking hanging beam. We made an example of two connection-points linking way in this catalog. Please let us know your specific requirement before you place any order. Since the profiled steel like round iron and thread iron is of big deflection, when its length over 9 meters, we suggested you to use multiple units.
