Practical methodology for operational layout of commercial skyline thinning systems

Creator:

Cornell, Jennie L., Kellogg, L. D. (Loren D.), and Oregon State University. Forest Research Laboratory

Abstract:

On-the-ground harvest unit layout, especially in skyline-thinning operations, is critical to meeting multiple resource objectives of the land manager and maintaining the economic viability of the timber harvesting operator. This phase of an operation can optimize the layout and harvesting of a sale or unit. Detailed layout by a knowledgeable...

Skyline analysis with log drag

Creator:

Tobey, Allen C.

Abstract:

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...

The dynamic behavior of a cable logging skyline and its effects on the tailspar

Creator:

Womack, Kevin C.

Abstract:

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...

Comparison of skyline carriages for smallwood harvesting

Creator:

Balcom, John Charles

Abstract:

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...

Field measurement of cable tensions for skyline logging systems

Creator:

Sessions, John and Oregon State University. Forest Research Laboratory

Abstract:

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...
