2. Follow the safety instructions and clean the workpiece and the lower magnetic plate of the lifting magnet if
necessary.
3. Place the lifting magnet at the centre of gravity of the load. The lifting magnet is pre-tensioned slightly. The
effect differs depending on material thickness, but it avoids unintentional
in a vertical or other forced position.
4. Align the lifting magnet ideally according to the desired application.
5. Press the lever down as far as it will go into the ON position. Check that the safety tab has clicked into place
correctly.
6. Move the load hook to the required position and lift the load by about 10 mm to check its deformation and the
magnetic holding force.
7. Now move your load slowly and evenly, and avoid vibrations or impact.
8. After the load has been set down completely and safely, you can deactivate the lifting magnet. To do this, press
the safety tab using the heel of your hand and move the lever upwards into the OFF position.
Basic information related to the handling of magnetic lifting gear, in particular TML
The magnetic surface is located on the underside of the lifting magnet and has different magnetic poles which
generate the magnetic holding force through magnetic flow when activated. The maximum holding force that can
be achieved depends on different factors which are explained below:
Material thickness
The magnetic flow of the lifting magnet requires a minimum material thickness to be able to flow completely through
the load. If this material thickness is not given, the maximum holding force is reduced in accordance with the
material thickness. Conventional switchable permanent magnets have a deeply penetrating magnetic field similar
to tree tap roots, and require a large material thickness to achieve the maximum holding force. The compact
magnetic field of the TML magnets is similar to a shallow root and achieves maximum holding force even with small
material thicknesses. (See table in this operating manual)
Material
Every material reacts in a different way to penetration of the magnetic field lines. The load-bearing capacity of the
lifting magnets is determined using an S235 material. Steels with a high carbon content or whose structure has
been changed by heat treatment have a low holding force. Foamed or porous cast components also have a lower
holding force, so that the given load-bearing capacity of the lifting magnet can be downgraded on the basis of the
following table.
