Abstract
A crawler is disclosed for traveling through a workpiece such as a pipeline and inspecting the same for defects. The crawler is a completely self-contained, self-propelled and self-operated vehicle adapted to travel through a pipeline, stop at particular locations such as a girth weld between adjoining sections of pipe, inspect the weld, for example by X-raying it and then proceed onto the next location to be inspected.
