Describes the use of ultra high density molecular polyethylene (UHMWPE) fiber rope as a replacement for steel wire rope in logging applications. The rope characteristics are compared to wire rope. The research is supported by Oregon Occupational Safety and Health Administration grants to redesign work sites using ergonomic improvements. Potential ergonomic gains are shown as heart rate reductions for logging tasks and improved recovery after exertion. Issues are raised about end- connectors, abrasion, stored energy, spooling, and how to incorporate synthetic rope in logging planning. Some early gains in effectiveness are noted and potentials for improvements identified. Future research is funded to look at important issues in projects with industry cooperators and on synthetic rope properties.
