Evaluation of productivity, machine rate, and costs on TAF skidder (case study: In Kheyroudkenar Forest)
Abstract
Transportation of wood from the cutting areas to the roadside imposes highest expenses in the whole logging operations. This research deals with this matter and studies the production and cost rates of TAF Skidder in cut-to-length system. The study was carried out in Kheyroudkenar Educational and Research Forest Station at Nowshahr, Iran. Using continuous time studies, the effective factors of skidding including winching distances, volume, slope, number of logs and tree species were identified and recorded. Overall, 46 turns were recorded on TAF, and the collected data were analyzed and skidding models were developed. The results showed that the production rates for TAF were 5.93 m³/hr (including delay times) and 8.33 m³/hr (no delays). Production costs were 74,861 and 53,279 Rials/m³, respectively. Studying the changes in each variable while the other variables kept fixed showed that, except the annual utilization of the cost of machinery produces a parablic function, factors have a positive linear relation with cost.
