ABSTRACT:
A self-propelled lateral inspection apparatus includes a propulsion motor that drives friction members to propel the apparatus along an inside surface of a main sewer pipe. The apparatus also includes a main camera and a lateral camera. The main camera is used to view the relative positions of the lateral camera and an opening to a lateral sewer pipe to be inspected. The lateral camera is interconnected to a push rod cable having a flexible core and lateral camera wiring encased in a resilient shell. A rotate motor and a tilt motor act on a launch chute assembly to properly align the lateral inspection camera with the lateral sewer pipe opening. A drive assembly, including a drive motor, at least one drive gear, and at least one pressure roller, inserts and retracts the push rod cable and lateral camera into and from the lateral sewer pipe.
