Technical and economical analyses of short distance koller K 300 yarder for the studies on transport of compartment in Artvin region

The method used in transportation of raw forest products can be performed in two phases. The first phase is called " the minor transportation" which is the extraction and hauling of the logs from the felling areas to the landings and intermediate depots. The second phase is "the major transportation". This phase covers the hauling operation from landings and intermediate depots to the log yards or the mill yards. The forestry transportation of harvested woods from compartments is the most difficult and the most expensive operation. Since forests are generally located on high and steep slopes of mountainous area in Artvin province extraction from compartment is extremely difficult procedure. The studies were carried out in the harvesting areas of Salelet Tepe and Kuvabt in forest District of Taşlıca, Beşağıl in Forest District of Saçinka and Hamamlı in Forest District of Ortaköy. It was determined that the productivity values were 4.997 m3/hour, 4.755 m3/hour 6.60 ster/hour (4.620 m3/saat) in transportation of softwood, hardwood and firewood respectively. Furthermore cost of transportation from compartment was calculated 6.642 $/m3 in transportation of softwood. The same values are 6.860 $/ m3 in transportation of hardwood and 5.321 $/ ster (7.048$/m3) in transportation of firewood. In conclusion hard woods which transported from compartment by the short distance Roller K 300 with mobile winch skyline system would be considered more productive and economic than soft woods in thinning areas for the Artvin region.Key Words: Short distance Roller K 300 yarder, Artvin region, transport of compartment, maintains area, productivity vn
