Abstract

Self-driven vehicle for pipelines comprising: a cylindrically designed vehicle body (1) through which and/or around which the pipeline's (10) medium flows, a drive unit (2) on the vehicle body (1) which resiliently bears against the pipeline's (10) internal surface, a hydraulic system which powers the drive module (2), a power supply system for operation of the hydraulic system, and a controller (22) which at least controls the vehicle's movement in the pipeline (10).
