ABSTRACT:
An apparatus for inspecting a lateral branch of a main pipeline from within the main pipeline comprises an inspection device adapted to fit within the lateral branch, a semi-rigid rod having a leading end attached to the inspection device, an aligner for aligning the inspection device with a lateral branch, and a rod pusher for advancing the rod and inspection device into the lateral branch. The rod pusher is pneumatic and pushes the inspection device into the lateral branch by repeatedly gripping, advancing, and releasing the rod.
