Abstract
This study was conducted to evaluate the productivity and the operational costs of the Chuncheon Tower-yarder, a skyline yarding system used in Korea. Detailed time study data were collected from 4 thinning sites in Japanese larch (Larix leptolepis) stands; one site for uphill yarding and three sites for downhill yarding. This study derived regression models to estimate the average cycle time (sec.) for uphill and downhill yarding. The average yarding cost was $12,844won/m^3$ for uphill yarding, while downhill yarding cost was $13,221won/m^3$. The average yarding time was 239 sec/cycle for uphill yarding, while downhill average yarding time was 274 sec/cycle. We found that uphill yarding productivity was higher when the operation system was examined under the same work conditions (i.e. standardized comparison) except yarding directions for both uphill yarding and downhill yarding.
