Rama IX Cable Inspection — Redefined.
Today, Span Systems International (Span) carried out an advanced stay-cable inspection on the Rama IX Bridge using the Magnetic Induction Robot developed by DYWIDAG Germany.
This state-of-the-art system generates a magnetic field of 1.9 Tesla
(for comparison: a medical MRI is 2.5 Tesla)—
allowing us to see inside each strand, detect micro-level wire defects, and assess structural integrity without opening the cable.
A world-class technology trusted on major European bridges, now applied in Thailand through the collaboration between Span × DYWIDAG.
Deeper insight. Higher precision. Next-level safety.
Proud of our engineering team and proud to push Thailand’s bridge inspection standards forward.
