A permanent magnet lifter is a lifting device that uses permanent magnets to lift and transport heavy ferromagnetic materials such as steel plates, pipes, and other metal objects.

It is primarily used for lifting ferromagnetic materials, including steel, iron, and nickel-based alloys.

Some manual magnetic lifters allow for magnetic force adjustment. By rotating the control switch, operators can modify the magnetic strength to accommodate different weights and sizes of objects.

Manual magnetic lifters are best suited for regularly shaped metal objects. If the object has an irregular shape, the uneven magnetic distribution may affect lifting stability.

When selecting a magnetic lifter, consider lifting capacity, magnet type, safety features, size and design, durability, and structural strength to ensure safe, efficient, and reliable operation.

First, verify that the lifting magnet’s capacity exceeds the weight of the intended load.

Check that the load surface is clean to ensure proper adhesion.

Use a safety shim (a thin metal plate placed between the magnet and the load) to test lifting performance.

During testing, lift the load a few centimeters off the ground with the safety shim in place.

If the load remains securely lifted with the shim, it confirms that the magnet can safely lift the load without the shim, ensuring safe operation.
