Shape of Skidder Productivity Function for Ground Based Skidding System in Caspian Forests
Cut-to-length (CTL) timber harvesting technology currently accounts for approximately 90% of Caspian forests. The technology involves felling, branching, cross-cutting, and then the skidder carries the logs to a landing, where the timber is temporarily stored, sorted and assembled for transportation to the mill. Cut-to-length systems typically require less labor, less access road construction, ...

متن کاملSoil Compaction and Porosity Changes Caused During the Operation of Timberjack 450C Skidder in Northern Iran
Skidding by means of heavy forestry machinery can affect soil physical properties. We assessed the effects of ground based skidding on soil bulk density and total porosity under the Iranian mountainous forest conditions. Treatments included a combination of four levels of traffic intensity (1, 3, 6, and 15 passes) of a Timberjack 450C rubber skidder and two levels of slope (<20% and >20%). The ...
متن کاملeffects of ground-based skidding using wheeled skidder timberjack 450c on forest soil physical properties (case study: gorazbon disrict, kheyrud forest)
forest harvesting operations for extracting of forest products in these trails, causing extensive damage in a wide range of soil and its productivity every year, therefore it is necessary to research about degradation of soil properties should be down. the aim of this study was investigate changes in the skid trails soil physical characteristics due to wheeled cable skidder traffic by measuring...
