- Abstract:
- Cable yarding is a widespread method for wood extraction in mountainous regions in most parts of the world. Especially in Austria, extraction by cable is relevant at 57% of the forest covered land since it has terrain slopes of more than 30%. Since it is an elaborate and expensive extraction method, the productivity of cable yarding systems is of great interest for decision makers. Work- and time studies are a comprehensive domain in the scientific field of forest engineering to create productivity models for cost estimation, simulation and other decision support systems or simply to compare different harvesting systems. The present work investigates work studies on cable operations published in the scientific literature, in regards of assessment methods and to establish a knowledge base on cable yarding productivity models. A comprehensive literature research is performed to identify relevant studies in a first step. Information about the investigated extraction campaigns in matters of site specifics, stock specifics, the employed equipment alongside the work study-methods as well as the statistical approaches for model creation are collected. In a next step, the gained data and models were systematically analyzed to compare different harvesting systems in regards of productivity and their influencing factors.
