Do’s and Don’ts When Positioning the Lifting Magnets

Posted on June 6, 2019

Ferrous plates come in wide variations of dimensions. But how should you properly place your lifting magnet(s) in order to achieve its greatest safety factor. Let’s take a look at 3 common scenarios.

When load is wider than the length of the magnet (the most common case):
Do:
Place the permanent lifting magnet across the plate’s length to increase holding at possible point of peel.
Load Wider than Magnet Length, Do's
Don't: Placing the permanent lifting magnet parallel the plate’s length does not maximize its magnetic attraction.
Load Wider than Magnet Length, Don'ts

For narrow plates (Width of load is less than the length of magnet):
Do's:
Placing the permanent lifting magnet parallel to the plate’s length can maximize their contacting area.
Narrow Plate, Do's
Don't: Only a portion of lifting magnet’s poles are in contact with the narrow steel plate.

For loads longer than maximum recommended length:
Do:
Multiple magnets need to be connected by a spreader bar and springs, and positioned to evenly distribute load’s weight on each unit. Each case may vary depending on the steel plate’s dimensions.
