Rectangular lifting magnet EP
The EP type rectangular lifting magnet (electromagnetic gripper) is designed for handling castings and slabs. The lifting magnet with special shaped pole shoes is adapted to lift sheet metal coils and wire with winding axis horizontal. The EP electromagnet improves internal transport in steelworks, shipyards and foundries. The use of the EP electromagnet shortens loading times in ports, railway terminals and steel warehouses.
The EP electromagnetic gripper is reliable, very robust and designed for S3 75% intermittent periodic duty. The electromagnetic gripper is characterized by high attractive force, high lifting capacity and high handling efficiency. The EP electromagnet has a high-quality winding made of aluminum tape with the highest class of insulation. This makes it resistant to high temperatures and very durable.

Working principle of the lifting magnet
The electromagnetic gripper in a non-magnetized state (disconnected from the power supply) is lowered onto the load by the crane operator. After applying the supply voltage from the control cabinet, direct current flows through the electromagnet winding. A strong magnetic field is generated at the magnetic poles of the gripper. This operating state is called magnetization. The gripper attracts the load until the operator turns off the power. This operating state is called demagnetization. The digital AC/DC converter installed in the control cabinet is responsible for the quick discharge function of the circuit and regulation of the electromagnet power. The Tipping function enables quick completion of an individual customer order, e.g. by lifting only one sheet of metal from the entire package and delivering it to the desired loading location.
Why choose our rectangular lifting magnets?
EP rectangular electromagnetic grippers are designed mainly for lifting and transporting longer elements, such as sheets, slabs, slabs and sections. In the version with pole pieces, they are reliable when transporting sheet metal and wire coils with a horizontal axis. Depending on the material being lifted, we produce single-, double- and three-pole electromagnetic grippers. This design allows for optimal field coverage and lifting force for the handled assortment. We use materials with the highest magnetic permeability and windings with the highest insulation class. We also provide electromagnetic grippers for working with material at temperatures up to 650°C. Thanks to the use of four-quadrant control, we have reduced the magnetization and demagnetization time of the grippers to a minimum, which significantly shortens the reloading time.
Price of the rectangular lifting magnet and delivery date
Based on the type of material being lifted and the required lifting capacity, the appropriate type of lifting magnet is selected and its price is determined, which depends primarily on the power of the installed electromagnet. Depending on the ambient temperature and the transported material, electromagnets are offered in a standard version or equipped with a thermal shield (HT version).
The delivery date of the device on order is usually 6 - 8 weeks. We also fulfill orders with an accelerated deadline. Magnetix also has a large warehouse of electromagnetic grippers available immediately.
Magnetix also carries out comprehensive deliveries of electromagnetic grippers including a crane modernization project, power supply systems, control systems and mechanical and electrical assembly. The price of a comprehensive lifting electromagnet delivery with assembly is calculated individually and depends on the complexity of the installation and the scope of work.
