Detailed Performance Data; Load Capacity In Kg; Load Capacity In Lbs - Alfra Tmh 50 R Bedienungsanleitung

Detailed performance data for the hand-operated lifting magnet TMH 50
flat material
Values shown for load capacity of the TMH 50
force with 0° deviation from the load axis and additionally under a 90° inclined load. The safety factor corresponds
to at least 3:1 in all cases.

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 gap forms 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
Immediately stop the lifting operation 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 & 3.
