NOTE: Lifting Values for the DynamicLift™ Magnets are stated at 33% of the actual value. We recommend when lifting sheets over 8’, use 2 or more lifts on a spreader bar to prevent sheet fl exing, sagging or peel-off. Thin material is susceptible
to magnetic bleed through, resulting in two sheets being lifted at once. Round Item Lifting Values are based on ideal conditions. Pipe length, wall thickness, diameter and surface condition can all affect the magnet’s performance. Please
consult the factory before specifying these magnets for use on round materials. *These maximum sheet lengths are selected due to the sag characteristics of the specifi ed sheet. The item to be lifted must cover the entire length and width of
the magnetic poles to properly engage and release the part.
Even though a magnet works through non-magnetic bodies such as dirt and non-
ferrous materials in general the best effi ciency of any magnetic lift is achieved when
the poles (the areas or surfaces of the magnetic lift which make contact with the load)
make complete contact with the load. It is therefore recommended to:
1. Never stand under load being lifted or lift over any people. Always use extra caution.
Only use on thick material that does not fl ex or bend.
2. Clear any foreign material from the load as much as possible before setting the
magnetic lift on it. Avoid, as much as possible, setting down the lifter in places on the
load that are very dirty or deformed.
3. Check the surface condition of the magnetic poles to make sure they are fl at and not
damaged or corroded during its time in use.
4. Thin or large sheets that sag may cause the sheet to peel off the face of the magnet.
(See chart below)
5. Keep the surface of the DynamicLift™ and materials clean and free of chips, oil, slag,
welding-beads, dirt, etc. This can be done by wiping the surface of the magnet off
frequently with a wire brush, or shop rag.
6. After a period of time the pole faces may become somewhat rounded, reducing the
magnets effectiveness. Poles can be resurfaced up to 0.80” maximum.
EFFECTS OF UNBALANCED LOADS
Maximum lift force achieved by a magnet is when the direction of force is perpendicular
(90º) to the metal surface. If a load is tipped at an angle shear forces, slide forces, friction,
peeling forces associated with moments, cantilevers, impact forces associated with
bumping the load as it is conveyed can cause the lift to fail.
• Check magnet/load balance by raising the load off the ground by a few 2” - 3” only.
• Never lift a load at an angle in excess of 5º from horizontal.
• If unbalanced: Lower load, reposition magnet and test the magnet/load again.

Annual Calibration, Repair and Recertifi cation Services
To ensure that your DynamicLift™ Rare Earth Lift Magnet is performing to its optimal
level, an annual calibration check at our facility is recommended. Under an “Ideal
Conditions” environment, our state of the art equipment will perform a series of tests
to determine the current “de-rated” holding value of your magnet. This holding value
must meet or exceed the value stated on your DynamicLift™ Rare Earth Lift Magnet.
If the stated holding value is met, and you do not require any additional maintenance,
we will return the magnet to you along with written documentation of the test results.
If the stated holding value is not met, we will contact you with the results of the test
and our recommendations for returning the magnet to its original condition. Options
may include; the resurfacing of the magnet’s poles or the repair of any broken
components.
INSTRUCTIONS: Please contact our customer service department at [phone]
to obtain your Customer Supplied Material (CSM) number. At this time, you will be
required to supply a P.O.# for the test procedure described under “Annual Calibration”.
Current fees for this procedure can be obtained by contacting the number listed above.
