Newt segment and pigging

Scraper segment for the active propulsion of a pig in particular elongate hollow bodies, preferably in gas and oil pipelines, with a drive, the at least one motor (21), at least one support element (1), via which the scraper segment on an inner side (5) of the can support the hollow body (10), and at least one supporting element (2), which is movable by the motor along a longitudinal axis (6) of the scraper segment, wherein the support element (1) to assume a supporting position pivoted to the supporting element (2) arranged and a supporting force exerted in response to a longitudinally on the supporting element (2) force is produced in the supporting position. Furthermore, the invention relates to a scraper with a corresponding scraper segment.
