Visual for NBI Inspections and Magnetic Flux Leakage (MFL) To Peer Through the High-Density Polyethylene (HDPE) Cable and Locate Inside the Steel HDPE Sheathing.
CableScan® is a patented robotic cable-stay inspection service that consists of two inspection services. The first utilizes high-definition video technology. CableScan® visual does not require lane closures, man-lifts, bucket trucks, or night-time inspections. It is a self-propelled robotic system controlled by a base station that receives HD video and MFL transmissions from the robotic crawler.
By utilizing Infraspect’s robotic CableScan® any imperfections along the cable stay are recorded as well as the length traveled along with the stay, and the corresponding length traveled along the deck. We can provide the length and size of cracks and other abnormalities on the cable stay. The internal technology in CableScan® utilizes MFL to locate section loss and corrosion through the HDPE sheathing on the exterior strands of steel inside of the steel cables.

Multiple Views, Angles & Detail Recorded
CableScan® inspections take into account all of the required parameters of Federal Highways (FHWA) for bridge cable inspections. The location of any abnormalities along the cable stay are recorded so follow up maintenance and reviews can be performed. In addition the the location on the cable as well as the location on the ground are recorded so that maintenance crews can park their truck directly under the affected area. This makes is easier to instantly access the correct location for repair work.
By maintaining a historical record of the inspection, any inconsistencies however slight can be reviewed over multiple inspection cycles to quickly determine if there has been any increase in deterioration so that further repair action can be taken if needed.
Updating 50-Year-Old Manual and Subjective Inspections With Modern Technology and Robotics
CableScan® MFL robotic inspection unit can locate and quantify inside an HDPE cable on the outside steel layer and be used as a screening tool to know when further action may be needed. This advancement for NBI and interim inspections provides more quantitative data than ever viewed before.
Steel Bridge Cable Visual Inspection and HDPE Cable MFL Inspection
Through the use of Infraspect’s new patented and proprietary testing equipment and procedures, our inspectors can perform cable condition assessments of bridge cables identifying loss of section and broken wires through the HDPE sheathing in the top layer of steel strands inside the cables. Our inspectors do not need cranes or bucket trucks.
In addition, they do not require lane closures. CableScan® is a self-propelled robotic inspection system that attaches to the cable and travels along the full length of the cable transmitting data to the inspector’s laptop.
CableScan® can identify corrosion, loss of section, and broken wires on-site on the outside steel layer as well as cracks, holes, and other anomalies on a cable. Infraspect delivers a comprehensive report identifying individual strand conditions as well as overall condition assessments of the cable system for the bridge.
In addition, Infraspect can take a high-definition video of the entire Cable Stay and locate the length of a crack or anomaly on the exterior of the cable as well as its position on the structure. With each inspection cycle, a comparative analysis of any anomalies over time can help with early repairs and more efficient asset management potentially saving lives. Safer for the inspector and safer for the traveling public.
