Development of the small yarder system (AcarMHH300) for logging from forest stands

Abstract

Extraction process of wood raw materials, from forest stand to the nearest forest road, is very difficult and expensive stage having highest environmental damages. Forestry activities where limited to the use of technology have great importance in terms of technical, economical, ergonomic and environmental in mountainous terrain especially. The aim of this study is to develop an economic and ergonomic system to ensure the transport of logs to the nearest forest path by cable line and also to provide an alternative skyline system to existing costly methods in air transportation. In our country, the only method used to transport of logs in the air is the forest airlines. Differences of the proposed system from other airlines (expensive and imported) are more simple, ergonomic and economic. Thus, possible damages in both logs and environment will be minimized during the transportation and an ergonomic work will be done. In this system, drummed forest tractor was used for the power supply and 10-12 mm thickness steel cable as main cable was used. Locking wagon on the main cable was produced in special mechanic industry and it was integrated to the system. This wagon has 6-8 mm thicknesses ground cable and process of pulling the timber up to the forest road by cable wrapped to drum was completed. Ring system is used in the pulling of logs to uphill direction. Installation procedures of this system in the field can be performed in a very short period as a few hours in a simple manner. This research was tested in Mountainous Eastern Black Sea Region at the field condition formed conifer forest in the spring 2016. Controlled pulling to upward by using engine power was taken essential. Based on this study, drawing speed and efficiency on the motor system were found 1,05 m/s and 3,057 m3/h, respectively.  Average skidding distance was 140 meter in both cases. Previously imported heavy forest airlines are not being profitable due to high depreciation price and inappropriate for the magnitude work. This system to be developed will be the first in our country. According to the forest airlines used in this world, the advantages are as follows: The tower is not required, practical, cheaper and portable, and it does not need a big drum.
