Caldwell RELM - Round Electric Lifting Magnets
All capacities are based on lifting clean, smooth, flat, low-carbon steel plate with the full area of the magnet's lifting surface in contact with the load. Derating is required for plates or other loads with rust or scale. Do no use on material thinner than 1/4".
Note: When lifting 4' x 8' sheets or any sheets over 4' x 8', use two or more lifts on a spreader bar to prevent sheet flexing, sagging, or peel-off. Material less than 3/8" thick is susceptible to magnet bleed through, resulting in two sheets lifted at once.
