Example mm:
You would like to lift a plate which is 6 mm thick and made of S235. The plate stands vertically, i.e.
at an angle of 90°, in your shelf rack and your magnet is ideally positioned, as shown in figure 1.
Material thickness:
Material:
Alignment of the load: 90° tilted; load hook facing upwards
Example INCH:
You would like to lift a plateof mild Cold Rolled Steel (CRS) which is 1/4 inch thick. The plate
stands vertically, i.e. at an angle of 90°, in your shelf rack and your magnet is ideally positioned,
as shown in figure 1.
Material thickness:
Material:
Alignment of the load: 90° tilted; load hook facing upwards
Maximum load weight with 3:1 safety factor = 360 kg x 100 % x 30 % = 108 kg
Maximum load weight with 3:1 safety factor = 800 lbs x 100 % x 30 % = 240 lbs
ADJUSTABLE SHOCK ABSORBER
An oil filled shock absorber is incorporated on the backside of the magnet in order to absorb any recoil
energy of the lever. The thinner the material to be lifted the higher the recoil energy to be absorbed.
The set screw on the backside of the magnet makes it possible to adjust the shock absorber variably,
so that the upward movement of the lever is controlled and operates smoothly. This adjustment should
be made by using a flat-blade screwdriver.

6 mm max. load-bearing capacity at 0° = 360 kg (see table 2)
S235 holding force, subject to material = 100 % (see table 1)
Load-figure corresponding to direction = 30 %
1/4 inch max. load-bearing capacity at 0° = 800 lbs (see table 2)
mild steel holding force, subject to material = 100% (see table 1)
load-figure corresponding to direction = 30%
