The SPiDER scanner from CUES can calculate its position in the manhole shaft by using its sensor data to measure its incremental motion instead of the payout cable. It weighs less than 30 pounds and can be hand-carried to easements or other previously difficult-to-access sites. This wireless portability is possible because the processing computer and battery supply are built into the scanner. It collects millions of 3-D measurements during each manhole inspection, so the manhole can be measured to better than 5 mm accuracy. The point cloud can be used to evaluate the structural changes in a manhole before and after rehab. It also provides live-video stream and recorded MPG video, making it an ideal wireless tool for I&I studies. 800-327-7791; www.cuesinc.com.
