Lifter magnets require good surface condition to achieve maximum lifting. Ground or machined surfaces are ideal, but a good clean surface or a forging or casting is acceptable provided sufficient flat area is available for magnet contact with the work piece. Recommended Lifting capacity is for flat, ground, clean ferrous plates derated by a factor of three. The safety factor is required due to such variables as surface condition, contact area, alloy content and material thickness and may need to be increases if these condition are particularly adverse.
