This paper describes a mathematical formulation and a computer program
in basic language for analyzing the load carrying capacity of skyline
systems using the effects of log drag. The actual log and ground geometry
are used in the analysis of the payload capacities for standing, live and
running skylines. The...

Initially, a small experimental study was undertaken to examine the influence of incline on the frequency of taut cables. The experiments consisted of exciting a short cable at angles of incline from zero to 90 degrees and at various tensions. The results from these experiments shows a small effect due...
Three skyline carriage types are analyzed on the basis of their operating characteristics and limitations. Their effect on productivity
is expressed as cubic feet per hour yarded to the landing. These carriage types, tested as part of Oregon State University's School of Forestry Smallwood Harvesting Research Program represent those which...
In recent years, a great deal of research in North America has been directed toward refining methods of assessing the load-carrying capability of skyline systems. Little effort has been directed, however, toward field measurement of cable tensions for skyline logging systems to facilitate initial tensioning of unloaded skylines or to...
