PIPE INTERNAL TOWING CARRIAGE

摘要

PIPE INTERNAL TOWING CARRIAGE A pipe internal towing carriage comprises friction rollers intended for engagement with the internal periphery of the pipe, the friction rollers being mounted successively on a drive shaft such that their axes of rotation are mutually parallel and intersect the axis of rotation of the shaft. The shaft has a stepped configuration, each of the steps carrying one of the rollers, the steps being axially offset relative to each other lengthwise of the shaft.
