ABSTRACT:
An elongated cable structure of rigid and flat transverse cross-section for protecting conduits of various types includes interior axial lines of high tensile strength which may be used to suspend equipment from one cable end and to force the equipment axially past obstructions in a well hole. The structure may be raised and lowered in the well hole by means of exterior teeth which are firmly secured to the underlying tensile lines project from the surface of the structure to mesh with traction drives.
