Assessment of alternative log debarking methods by considering productivity

Assessment of alternative log debarking methods by considering productivity Abstract:  In Turkey, timber debarking stages are generally carried out by using axes. However, this method takes a lot of time and requires more work forces. Besides, the use of axe may cause wounds on trees during debarking activities. In recent years, chainsaw mounted debarking tools have been widely used in debarking stages due to performing jobs quicker with less labor force. In this study, two different debarking methods including using axes and debarking tool were analyzed by considering productivity. The field studies were conducted in Brutian Pine (Pinus brutia Ten.) stand located in Bahce Forest Enterprise Chief of Osmaniye Forest Enterprise Directorate in Adana Regional Forestry Directorate. As a result of study, the productivity of chainsaw mounted debarking tool was found to be five times higher than that of using axes for debarking. Keywords:  Debarking, chainsaw mounted debarking tool, axe, productivity Alternatif kabuk soyma yontemlerinin verim acisindan incelenmesi Ozet:  Ulkemizde odun hammaddesinin kabuklarinin soyulmasi asamasi genellikle balta kullanilarak gerceklestirilmektedir. Ancak, bu yontem cok fazla zaman almakta ve daha fazla isci gucu gerektirmektedir. Ayrica ormanda kabuklari soyulmadan kalan urunler boceklenme riski ile karsi karsiya kaldigindan, zaman kaybetmeden kabuk soyma islerinin bitirilmesi gerekmektedir. Son yillarda, motorlu testereye monte edilebilen kabuk soyma aparatlari, islerin daha kisa surede tamamlanmasi ve daha az is gucu gerektirmesi gibi faktorler nedeniyle ulkemizde daha yaygin kullanilmaya baslanmistir. Bu calismada, balta ve kabuk soyma aparati kullanilarak gerceklestirilen iki farkli kabuk soyma calismasi verim acisindan incelenmistir. Arazi calismalari Adana Orman Bolge Mudurlugu, Osmaniye Orman Isletme Mudurlugu, Bahce Orman Isletme Şefligi sinirlarinda kizilcam ( Pinus brutia  Ten.) mesceresinde uygulanmistir. Sonuc olarak kabuk soyma aparatinin kullanilmasi durumunda balta ile kabuk soymaya oranla saatlik verim yaklasik bes misli daha yuksek bulunmustur.
