Productivity Assessment of A Loader By Using Drone Captured Images

The loading operation has an important function in the smooth execution of forest operation as it is a transition activity between timber extraction and long-distance timber hauling. Thus, it is crucial to estimate productivity of loading operation and determine the main factors effecting the productivity. The time study analysis is commonly used in productivity estimation of forest operations. Traditional time study analysis, usually done by utilizing time watch, requires two or more personnel who closely observe the logging operation and measure the logs at the landing. However, this field work can be dangerous since several equipment work and move around the operation site. In this study, the productivity of a loader was estimated based on video images which were taken with an "DJI Mavic Pro" model Unmanned Aerial Vehicle (UAV). The study was conducted in a Brutian pine stand located in Muğla Forest Enterprise Chief in the city of Muğla in Turkiye. It was found that the productivity of the loading operation was 25.52 m3/hour. The results indicated that there was a positive significant relationship between productivity and product diameter and volume.
