Detailed Performance Data for Use on Flat Material

Values shown for the TML 400R's load capacity are based on material S235 JR (comparable to AISI 1020 Cold
Rolled Steel) with the maximum, vertical breakaway force at 0° deviation from the load axis and additionally under
a 6° inclined load in accordance with EN13155, in each case with a 3:1 safety factor.

The maximum dimensions of the loads to be lifted depend to a large extent on the geometry and flexural stiffness
of the work pieces. If the material bends, an air gap will form under the magnetic surface which will decrease the
load-bearing capacity significantly.
During each lift, watch for any deformation of the work piece that might occur and check for any air gap developing
at the edges of the magnetic surface contact area. You can use for instance a sheet of paper (80g/m
this. Spreader bars with additional magnets may be required to safely lift large or flexible loads.
Immediately stop the lift if there is any excessive deformation of the work piece or an air gap.
Never exceed load-bearing capacity given in the table 2.
