While drones excel at corridor mapping, track crawler robots provide high-resolution, contact-level inspection for OPGW and ADSS — especially useful for splice enclosures, clamps and earthwire attachments. These crawlers capture close-range video, thermal imaging and sensor readings while traversing conductors under controlled tension.

Benefits:

• Detailed inspection at splice points where aerial imaging is limited.

• Reduced exposure: robots replace risky human climbs for routine checks.

• Data continuity: repeatable inspection missions make trend analysis and predictive maintenance possible.

Operators are combining drone overviews with crawler inspections to deliver full-spectrum OPGW/ADSS health checks.
