CUES, a leading manufacturer of CCTV pipeline inspection equipment, has introduced an innovative new wireless manhole scanning technology: the SPiDER 3D manhole scanner.

The SPiDER scanner is the only truly wireless, color manhole inspection technology in such a lightweight and compact form, says Pierre Mikhail, director of CUES’ manhole inspection division. 

“The SPiDER scanner provides a new outlook on how manhole data is collected and applied,” Mikhail says. “While other cameras and inspection devices use a payout reel to determine how deep the camera is in a manhole, the 13 kg, tetherless, self-contained SPiDER typically is deployed using a telescopic mast or tripod for stability.

“It is operated with a tablet computer that controls the scanners and lights. This technology frees manhole scanning from problems associated with inaccurate, poorly calibrated cable counters and poorly managed cables. SPiDER does not require a truck or data/power cable for operational use. Scanning data is recorded on the unit.”

SPiDER collects millions of 3D points during each manhole scan that provides engineering and survey quality information about manhole geometry and condition. Information gathered can be used for structural assessment, pre- and post- rehabilitation analysis, hydrological surveys and for general condition assessment.

SPiDER produces textured point cloud renderings of manhole geometry to provide three-dimensional visualization that can be imported into a wide range of 3D viewers and can be delivered in these file formats:

  • 3D MPEG video
  • Point Cloud (.PLY) which can be converted to Surface Model (.STL), CAD Model (.DXF) and Virtual Model (.OBJ)
  • Manhole Report, using your preferred manhole inspection software

SPiDER provides a 190-degree field-of-view live video stream, an ideal tool for I&I studies that depend on live video to detect moving water.
