Rectangular lifting magnet EP
The EP type rectangular lifting magnet (electromagnetic gripper) is designed for handling sheet metal and slabs. The lifting magnet with special shaped pole shoes is adapted to lift sheet metal coils 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.

Principle of operation of the electromagnet
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 of the gripper. The gripper attracts the load until the operator turns off the power. This operating state is called demagnetization of the gripper. 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.
