Our permanent magnetic lifter can easily hoist 660 lbs/300 kg loads. It is made of strong N42 neodymium magnets, allowing for efficiently lifting kinds of steel materials without any electrical power supply on industry sites. The magnet features a heavy-duty chrome-plated hook and a flexible rotating shaft, making it easier to control the switch. The U-shaped groove is compatible with both flat plates and round steels, boosting a wider range of applications. Please clean the surface of the steel sheet before using the steel magnetic lifter, and do not stand under the lifted plate.
