Magnet Spacing - Eddyfi Technologies Magg 310 Manual

Magnet Spacing

The Magg™ 310 vehicle comes equipped with magnet cups to enable the vehicle to maneuver on a
vertical or inverted magnetically attractive surface. The magnet cups utilize rare earth permanent magnets
and cannot be disabled (or turned off).
The inspection surface must be carbon steel or alloy steel that has good magnetic properties. Most
structural steels are strongly magnetic. 300 series stainless steels and some other alloys are not. The
client may be able to identify their metal and look up its properties or test it with a magnet.
It is important to note that the magnet cups lose magnetic adhesion as they move away from the
attractive surface. The operator needs to pay attention to distance between the magnet cups and the
surface. If the magnets are too close to the surface, the Microtracs™ may not be able to overcome the
added friction for skid steering. If the magnets are too far away the vehicle may lose magnetic adhesion.
The distance from the magnet cups to the inspection surface can be adjusted by the operator by adding
or removing the magnet spacers. The thickness of the steel surface also affects the amount of magnetic
adhesion provided by the magnets.
Some considerations when determining magnet spacing:
•
Thickness of stainless, plastic, or concrete cladding over the carbon steel surface.
•
Uneven surfaces such as large welds.
•
Thickness of magnetically attractive surface (0.20in minimum is ideal).
•
Curvature of inspection surface.
