R.S. Technical Services RST Helix manhole inspection system
R.S. Technical Services’ new RST Helix manhole inspection system can be deployed from a CCTV vehicle, pickup truck or ATV, and is capable of scanning a 10-foot manhole in under one minute. The Helix has six high-resolution cameras that capture panoramic images of every surface as well as six active 3-D sensors that record spatial data points for precision measurements. Once the Helix reaches the bottom of a manhole, it returns and automatically transmits scan data to software where it can be reviewed in the office or in the field. 800/767-1974; www.rstechserv.com.

CUES wireless 3-D SPiDER Scanner
The SPiDER wireless, color manhole scanner from CUES can calculate its position in the manhole shaft by using sensor data to measure its incremental motion. It weighs less than 30 pounds and can be hand-carried to easements or other difficult-to-access sites. The processing computer and battery supply are integrated into the scanner, which allows portability. The SPiDER also provides a live video stream and recorded video that can be used for I&I studies. 800/327-7791; www.cuesinc.com.
