PROJECT TOPICConstruction, Infrastructure & Maintenance
Bridge Cable Inspection Climber
An infrastructure health monitoring concept examining split-ring circumferential clamping frames, motorized urethane drive rollers, and magnetic flux leakage (MFL) sensors to detect broken interior steel wires.
Non-Destructive Structural Infrastructure Auditing
- ✓Inspects high-tension bridge stay cables without erecting massive temporary scaffolding.
- ✓Detects internal broken wires through protective HDPE outer cable jackets.
- ✓Features a quick-latch split frame for rapid installation around cables in under 15 minutes.
The Engineering Challenge
Problem / Objective
Corrosion and fatigue wire breaks occur deep inside wrapped suspension bridge cables, invisible to standard visual audits.
