. Economics and design of a radio-controlled skyline yarding system. Logging, Skyline. Effect of Side Slope Under the Skyline Skylines are frequently set up with the skyline following the contour; thus, the ground slope laterally under the skyline may vary from 0 to 100 percent or more. A steep side slope sharply restricts the distance the skidding line can be pulled uphill, and, although the line can be pulled farther downhill, the total width of the skyline road is markedly less. This, in effect, reduces the area served by each skyline road. For example, in this study the rigging crew was ab

A steep side slope sharply restricts the distance the skidding line can be pulled uphill, and, although the line can be pulled farther downhill, the total width of the skyline road is markedly less. This, in effect, reduces the area served by each skyline road. For example, in this study the rigging crew was able to pull the skidding line only 100 feet slope-distance uphill from the skyline, but could pull it 300 feet downhill on a 70-percent side slope. If a skyline road is 4,500 feet long with no side slope, it would cover acres; a strip with 70-percent side slope would cover acres, a difference of acres (fig. 6)..
