DETAILED PERFORMANCE DATA FOR THE TML 1000 LIFTING MAGNET
Values shown for 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. This manual does not
contain any instructions for use on round material, as the TML 1000 is designed for flat material and round
material or arched objects may not be lifted.

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, if necessary, check for any air gap developing at the edges of the TiN-coated
magnetic surface (e.g. with a sheet of paper; 80g/m2). Spreader bars with additional magnets may be
required to safely lift large or flexible loads.
