Abstract The present invention relates to an internal conduit vehicle, also called a pipeline vehicle. The vehicle comprises first (2a) and second wheel assemblies (2b) that are rotated in opposite directions to move the vehicle along the pipeline or mutually independent to perform a more complex movement. Each wheel assembly (2a, 2b) includes a number of wheels (5) at the free end of wheel arms (4), each wheel (5) having a spin axis that is angled in respect of an axis of the chassis (1). Each wheel (5) is shaped as a rotation symmetric body with a big end and a small end, and is unilaterally mounted to a wheel arm (4) by its big end. |
