Abstract: | Tower yarders have recently been introduced to forestry in Turkey. Clarification of the productivity and cost of logging using
the tower yarder is often requested because the cost for machinery is a significant factor in all calculations concerning
mechanized operations. Machines are often extremely expensive compared with the low cost of labor in developing regions. In
this study, a new logging system using a tower yarder was compared with a conventional system using a stationary yarder in
terms of productivity and cost. The research was conducted in the northeast of Turkey, in 1989 and 1992. The productivity
of the tower yarder and the stationary yarder was found to be 5.655 m3/h and 5.002 m3/h, respectively. Harvesting cost was analyzed based on observed productivity. The harvesting costs of the tower yarder and
the stationary yarder were found to be 47,410 TL/m3 and 17,553 TL/m3, respectively. With the tower yarder, the machine cost reached 93.1 % of the harvesting cost while the machine cost using
the stationary yarder reached 71.1%.
A part of this paper was orally presented at the 3rd Annual Meeting of the Japan Forest Engineering Society (1996). |
