This completed project is the culmination of three projects:

  1. Plans to test the feasibility of using synthetic rope as a replacement for some wire rope applications in logging.
  2. Provide operational testing of synthetic rope used in static lines for logging to assess the wear and damage associated with using these ropes.
  3. Research and develop suitable end connectors for synthetic rope.
