Shields’ lifting magnets carry the highest safety ratings in the industry. With a 3x safety rating, the lifting magnets meet and exceed capacity thresholds. In layman’s terms, lifting magnets have maximum rated capacities, all different depending on the size of the magnet. If a magnet has a 660 pound capacity on flat steel and has a 3x safety rating, this is telling the user that the suggested load capacity is 660 lbs; however in ideal conditions under ideal circumstances, this lifting magnet will lift 1980 pounds. While this is never recommended, it’s serves as a guideline for safety and frame of reference.
