Surface Condition: Magnet face and load surface must be clean and smooth. Capacity ratings are on flat, clean and polished steel plate with magnet face in full contact with the load surface. Paint, coatings, scale or other materials between the load surface and the magnet will adversely affect the holding power of the magnet.

Material Thickness: Lifting capacity is lower on thinner materials. Contact dealer for more capacity information.

Material Composition: Magnet capacity is for lifting low carbon steel. Other materials may reduce lifting capacity.

Load Size and Position: Consider thin sheets, rough and irregular surfaces, odd shapes and scale all affect holding power adversely when establishing a safety factor. Position the magnet on the load center of gravity. Loads that tilt or are not in balance and significantly affect the holding power of the magnet.

Capacity: Maximum attractive force is approximately twice the lifting capacity. Capacity ratings are on flat, clean and shiny steel plate with magnet face in full contact with the load surface. The above factors should be taken into account when determining appropriate safety factors for a given load. A minimum of 3 to 1 safety factor must apply, given the actual breakaway force for a given load.

Refer to ASME Standard B30.20 for inspection and operating procedures of Close Proximity Operational Lifting Magnets and read Manufacturer’s Operating Manual before using magnet.
