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
Magnet Spacing
The
MaggHD™ vehicle comes with the tracks spaced down from the main chassis plate using four
groups of 8mm and 4.5mm spacers (two groups per track). The vehicle comes with a kit of spacers to
accommodate a wide range of track spacing.
Use the following mounting hardware depending on the track spacers used:
•
When spacing the tracks between 6-12 mm (0.25-0.5 in), use M5x20 SHCS outboard and M5x25
SHCS inboard.
•
For spacing less than 6 mm (0.25 in), use M5x14 SHCS outboard and M5x18 SHCS inboard.
•
When spacing the tracks more than 12 mm (0.50 in), use M5x25 SHCS outboard and M5x30
SHCS inboard.
When remounting the tracks, make sure the whips are securely connected and the locking collars are
fully engaged. Be careful to not pinch the track whips, and route them upwards towards the top of the rear
crossbar.
