The gopher crawler is the intermediate member of a family of 3 robust wheeled camera crawlers. Pipe diameters from 6” to 24” pipe are possible with the use of various sizes of solid or pneumatic wheels and spacers. The camera can carry standard or pan and tilt cameras, but dues require a front mounted mini camera when negotiating 6” diameter pipe. For 4” pipe see the Mole wheeled crawler, and for 8” and larger or steerable applications see the Wolverine crawler. This crawler is best suited for lines up to 500’ in length.
