Abstract
A pivot drive, a pivot, a cutter drive, a cutting head, and a camera are mounted to a base, and a remote control system operates the pivot drive to pivot the cutter drive from a stored to a use position, operates the cutter drive to rotationally drive the cutting head, and operates the camera to provide images of the cutting head used to cut out blockages at lateral connections of relined pipes. The camera and the cutting head are positioned in a spaced apart relationship facing each other, with the base extending beyond the cutting head sufficiently to provide this spacing. Optionally, the camera is mounted to a trailing portion of the base and the cutter drive is mounted to a leading portion, with control lines for the pivot and cutter drives routed back past but retained separated from the cutting head to avoid damage.
