Özet

Harvesting operations in steep terrain are particularly challenging, especially in environmentally sensitive areas and in very dense forests that are prone to more damage when using mechanized equipment. A possible approach to limit the damage is that of integrating animal and mechanical equipment. A study was carried out to see what operational variables and to what extent are they affecting the time consumption of yarding pre-bunched stems in thinning operations applied to coniferous stands. Following a time and motion study of yarding operations it was found that the extraction distance and lateral yarding distance affected the variation of yarding cycle time. Within a work cycle, load attachment and detachment accounted for almost 65%, the rest being shared by other typical cable yarding functions. The statistics and models presented in this study may be of help in production planning, research and optimization.
