Cross-beam lifting magnets
The cross-beam lifting magnets (electromagnets or electromagnetic grippers) are designed for handling long sheets, bundles of bars, pipes and other steel profiles up to 18 m long. The lifting magnets mounted on the common cross-beam enable the handling of low-rigid materials with a high deflection coefficient, such as thin sheets, reinforcing bars, etc. Electromagnets improve internal transport and shorten loading time in steelworks, shipyards, ports, railway terminals and steel warehouses.
The cross-beam lifting magnets are reliable, very robust and designed for S3 75% intermittent operation. They have high attractive force, high lifting capacity and high handling efficiency. The electromagnets have high-quality windings made of aluminum tape with the highest class of insulation. This makes them resistant to high temperatures and very durable.
