The high-performance 6-inch crawler from Cobra Technologies is designed for pipes from 6 to 24 inches in diameter. Small enough to inspect 6-inch relined pipe, the crawler is available as either a steerable version with eight-wheel drive or as a non-steerable version with six-wheel drive. Machined from naval brass and stainless steel, it offers the same features found on Cobra’s 8-inch crawler, as well as a new PTZ camera (Version 9.0) with optional continuous 360-degree rotate function. Wheels are provided and a remote elevator for larger pipes is being designed. For more information: 800/443-3761; www.cobratec.com; Expo booth 7057A.
