MAgneT TMH 50
Values shown for load capacity of the TMH 50 are based on material S235 JR for the maximum, vertical
tractive force with 0° deviation from the load axis and additionally under a 90° inclined load. The safety
factor corresponds to at least 1:3 in all cases. This manual does not contain any instructions for use on
round material, as the TMH 50 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. This is due to the fact that, in case of bending, an air gapforms under the
magnetic surface resulting in a significant decrease of the load-bearing capacity.During each lift, watch for
any deformation of the work piece that might occur. 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/m
