R.O.V. offers several standard Inspection Systems that perform a variety of tasks. All of R.O.V.'s Inspection Systems have been designed with time savings and radiological dose savings in mind. R.O.V. can customize inspection systems based on customer requirements.
Ribbon Lift Crawler
The Ribbon Lift Crawler is designed specifically for PWR At-Power Entries. The technology is from R.O.V.’s INVADER System. Most at-power entries are in response to suspected steam leaks and to search for boron deposits or inconel 600 weld degradation while the plant is on line. The ribbon lift crawler may also be deployed to assist with inspections of any system component, to detect anomalies, for data gathering, or for project repair and/or planning.
Flexibility Through the Extendable Mast
The Ribbon Lift is an extendable mast which is deployed from an approximately one-foot container. The container houses three engineered ribbons that interlock when deployed, creating a rigid triangular mast. The mast can be extended up to twenty-six feet, vertically or horizontally, in water or in open air applications. When the ribbon lift is retracted, the interlocked sections are unlocked and rolled into three sections within the container, positioned for further deployment.
Ease of Maneuverability
Due to its small size, the ribbon lift, outfitted with a radiation tolerant, color, pan, tilt, zoom (PTZ) camera, is easily mounted to the turret of an R.O.V. Scarab I crawler. The crawler’s small but stable platform allows it to maneuver into tight areas and deploy a twenty-six foot mast through piping runs in order to investigate areas such as the reactor coolant pumps, steam generators, pressurizers and associated piping.
Modifications Made to the Standard R.O.V. Scarab I Crawler for the Ribbon Lift Application:
- Body Camera - A fourth camera is added to the Scarab I to monitor the ribbon lift movements.
- Standard Drive - Dual rubber cleated steel belt tracks.
- Lighting - Dual 100 watt, wet or dry, 110 VAC.
- Dimensions – Approximately 29” L, 16” W, 44”H (mast down) and 28’ H (mast up).
- Tip angle (mast full up) - 10° front to rear, 15° side to side – wheelie bar protected.
The Ribbon Lift Crawler is operated using the R.O.V. Standard VOCC.
