Detailed performance data for the TML 1000lb 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 EN 13155, in each case with a 3:1 safety factor. This manual does not contain any instructions for
use on round material, as the TML 1000lb 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
2
sheet of paper; 80g/m
). 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 or an air gap.
Never exceed the dimensions and/or the load-bearing capacity of the material thickness given
in table 2.
