Abstract
In parallel with the increase in the population in Turkey, there has been a significant increase in the amount of wood production in recent years. This increase, which occurs in the amount of wood production, makes it imperative to innovate in production of forest products. Especially in wood production, the use of portable and low-cost new technologies and machines has become important. Among these machines, portable winches have been used in forest operations in the world and in Turkey as well in recent years. These winches are very useful machines in terms of installation and uninstallation. In this study, the use of portable winch in the Sahilçamı plantation areas within the boundaries of Sarıyer Forest Operation Directorate affiliated to the Istanbul Forest Regional Directorate has been examined. As a result of the studies, the hourly yield of the portable winch at an average skid distance of 50 meters was found as 1.110 m3/hr and the daily yield was found as 8.800 m3/day. Hourly fuel consumption of the hand winch was determined as 1.4 lt/h.
