660 lbs Lifting Capacity: Built with N42 neodymium magnets, this permanent magnetic lifter can lift 660 lbs/300 kg loads. With an upgraded 2.5 safety factor, it is solid and reliable enough to lift steel sheets, blocks, rods, cylindrical, and other magnetic materials. Security Handle Design: The magnet for hoist is designed with a chrome-plated anti-collision handle. Press the safety switch to rotate the handle, avoiding the risk of accidental startup and ensuring security. The handle is rubber-wrapped for slip resistance and a comfortable grip. Heavy-Duty Chrome-Plated Hook: The hook of our hoist magnet is made from high-strength steel with a chrome finish. You don't have to worry about it breaking or deforming when lifting. Its chrome-plated surface is smoother, more rust-proof, and easier to clean. Operate Without Sweat: Our permanent magnet crane features a flexible rotating shaft, making it easier to control the switch. Just turn left to turn on the suction and right to turn off the suction. For added security, the limit bolt is designed to fix the handle. U-Shaped Groove: The U-shaped bottom groove is compatible with both flat plates and round steels, boosting a wider range of applications. This permanent lift magnet is an excellent sheet metal lifting tool for the electricity, engineering, transportation, and mining industries.
