Determination of forest skid trail density in Caspian forests, Iran
timber harvesting winching time study
2016/3/2
Calculation of Skid Trail Spacing (STS) is an important option to minimize the total costs of skidding. Construction of many skid trails increases the construction cost, it also results in more degrad...
Felling and skidding damage to residual trees following selection cutting in Caspian forests of Iran
bole injury logging skidder tree damage uneven-aged stand
2015/4/24
The felling and skidding damage to residual trees was investigated in a selectively cutting operation in the Caspian forest of Iran. The logging operation was performed by chainsaw and cable skidder. ...
Productivity and cost analysis of skidding with Timberjack 450C in forest plantations in Shafaroud watershed, Iran
forest operation wood extraction skidder time study Iran
2015/4/24
We present research results of timber skidding by a Timberjack 450C skidder in the path cutting of pine trees in Shafaroud watershed. Time studies were conducted to quantify the productivity and perat...
Analytical hierarchy process to choose the best earthwork machine in northern forests of Iran
best selection earthwork machine environmental criteria analytical hierarchy process northern forests
2015/4/24
This study attempts to use the analytical hierarchy process to choose the most appropriate earthwork machine for slope classes of 30–50% and 50–70%. Required data were collected by pairwise comparison...
Determination of correction coefficient of average skidding distance according to the existing road network in Alikia Soltan forest of Iran
theoretical average skidding distance real average skidding distance skid trails
2015/4/24
One of the factors in planning forest roads is average skidding distance which is calculated in projects from the map, according to forest road density, however it has a low accuracy. In this study re...
