TesTex’s Line Crawler
TesTex developed the Line Crawler to be able to provide video and LFET scans of Penstock lines.
Line Crawler features:
- Contains 8 modified LFET Pods, a modified Mux Box and Falcon Electronics
- The Viper drive is modified for better traction and has a flexible coupling so it can be manually adjusted to fit a range of pipe sizes
- Has Three IR cameras mounted to the assembly for forward and backward vision while remote steering
- The third camera provides a downward view of the penstock surface being scanned. The image from this camera shows the distance traveled while recording
- Each LFET pod is mounted to a specially designed sled that can be pulled or pushed through the penstock by the Viper
- Provides a scan width of 16” across the bottom of the penstock
- With 300’ of cabling it is able to scan 250’ lengths while also being able to traverse inside diameter transitions
