A permanent lifting magnet, also called as on/of rare earth permanent magnetic lifter, is a lifting device that has a block with the main body and a rotor. It has two magnets in the main body and rotor each. These two magnets, when positioned in the same direction, produce magnetic flux that reaches the metallic objects to be lifted.

This type of magnetic lifting device can attract, hold and release a flat ferrous part alternatively every time it raises from ground and lands on the ground, without manually turning a lever and without any electrical power supply. It is a necessity for loading and unloading steel plates from burn tables or anywhere that limits operator access, and performing repetitive lifting task.

Advantages

• Cheap
• No need electricity
• Using rare earth magnetic materials, suffice to lift small steel load
