Abstract

A device for use within a large diameter pipe which cannot be physically inspected having drive devices to power its movement, has an extended body suitable for insertion into the pipeline and at least two endless strips or bands which are attached in planes parallel to the apparatus long axis to form loops which pass over motor driven rollers. The loops are fed over several pivotable spring loaded outward directed rollers such that the loop sections of all the strips have approximately the same separation in the peripheral direction along the long axis of the device.
