This series which adopts unique magnetic circuit 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. It improves problem like big deflection when lift round steel and thread steel. There are two kinds: normal & high temperature type. Normally multiple units are used in operation, so two or four connection points are used for linking hanging beam. We made an example of two connection-points linking way. Please let us know your specific requirement before you place any order.
