Abstract
An hydraulically inflatable anchoring device for use in pipelines. A woven fabric of braided steel cable is employed as the outer cover of the device, being expanded and maintained against the inside of a pipeline by inflation of an elastomeric bladder within. The anchoring device is configured in the shape of a dumbbell, with a center section of lesser diameter than the ends, in order to facilitate movement through curved sections of pipe. The woven fabric is wrapped around the ends of the anchoring device and clamped in the interior thereof, so as to provide a greater length of fabric for frictional engagement with the wall of the pipe.
