ABSTRACT:
A mobile radiographic device for use in inspecting pipelines and the like, comprising an articulating aerial boom coupled to a mobile carriage vehicle. A pivot mount is rotatably coupled to the distal end of the aerial boom. A platform having a sliding rail is operatively coupled to the pivot mount. A mounting fixture is rotatably mounted to a cradle, which in turn is coupled to the sliding rail of the platform. A radiation source and a radiation detector are mounted on diametrically opposing sides of the fixture in order to illuminate the outer surface of a pipeline or other object with radiation. A first positioning means is provided for coarsely positioning the scanning apparatus relative to the pipeline. A second positioning means is provided for finely positioning the scanning apparatus relative to the pipeline. The second positioning means is operable from a remote location when the radiation source is illuminating the pipeline with radiation. The first and second positioning means provide a plurality of degrees of freedom for positioning the scanning apparatus.
