Abstract :

It is necessary to review and evaluate the operation of the system and determine appropriate methods forests due to topographic conditions are significant operational activities, products, transportation, and the road making the destructive activities of the Forest as the most expensive. In this study, Economic Evaluation to be considered LTT-100A skidding system upward. After field operation and time study, using the regression model, the model is proposed to predict skidding time. Among the components of each cycle skidding in Zetor, moving with load and moving empty most of the time per cycle and in the form of delays, technical delays included the most time. The model predicted the skidding time Zetor have meaningful skidding distance and slope. hourly production rate of 12/5 cubic meters per hour and the cost of producing these systems is achieved 119,795 rials per cubic meter. Because of the speed and its efficiency Zetor is low, thus in long intervals and in places where travel time is limited, use of this system is not recommended for skidding operations. But since the power of this machine is its high and rapid stabilization is done, the application of this system, is recommended to be combined with other systems.
