ABSTRACT:
Pipeline inspection apparatus is provided including a camera unit and associated illumination means, preferably a strobe flash unit, for recording on photographic film the images of internal surface portions of a pipe for detection of defects. The camera unit is moved longitudinally within a pipeline by a drive unit which preferably includes electric motors energized from a self-contained battery unit. Important features relate to means for automatically reversing the drive of the apparatus after it has travelled a predetermined distance and to mechanical features for facilitating movement of the device through bends and the like.
