Abstract
A life line support for the traveler of a safety harness includes an elongate flexible tensioned cable and a square tube loosely surrounding the cable defining an outside surface for receiving the traveler for movement along the tube. The traveler includes rollers and is formed in two parts which can open to engage around the tube from one side and held closed by the attachment of the life line. The tube is tensioned between wall mountings and the cable is tensioned relative to the wall mountings by additional springs pulling on the cable separately from the tube. The cable thus provides the support strength while the tube provides the rolling surface.
