PIPE SCARIFYING SYSTEM AND METHOD

摘要

The invention disclosed and claimed herein relates to a subterranean pipe tractor for moving and controlling a pipe scarifier. The subterranean pipe tractor comprises a scarifier connector that reversibly connects a scarifier to the pipe tractor; a drive mechanism for propelling the scarifier through the pipe when the scarifier is connected to the pipe tractor; and a power source that powers the drive mechanism. The power source of the pipe tractor may be an on-board power source or an external power source. The pipe tractor may include a hydraulic pump and an on-board electric generator powered by the source. The subterranean pipe tractor may include local controls for controlling local functions and remote controls used to control remote components, such as a high-pressure fluid source. The subterranean pipe tractor may optionally include a scarifier lift mechanism for lifting one end of the scarifier.
