Efficiency and ergonomic improvements for cable yarding operations in steep terrain

The main aim of the project is the optimization of cable yarding systems in mountainous regions. The application of synthetic ropes in installations (as guy lines for anchoring of tower yarders and intermediate supports, as well as extensions of the skyline) of tower yarders shall provide ergonomic and economic improvements. The rationalization potential by the introduction of radio controlled chokers will be investigated and the ergonomic impact shall be evaluated. An analyses of the technical reliability of the radio controlled choker systems will be carried out collateral. Time studies and heart rate measurements represent the methodical instruments and shall lead to the estimation of work force.
