Excerpt from Planning Single-Span Skylines In recent years there has been a grow ing demand for a yarding system that can economically transport logs from steep terrain without a dense access road net work. Such a system must also be able to transport logs without disturbing sensitive soils or damaging watersheds. And in many areas, the public demands that the logged area be esthetically pleasing to the eye. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This paper describes four computer programs for the logging engineer's use in planning log harvesting by skyline systems. One program prepares terrain profile plots from maps mounted on a digitizer; the other programs prepare load-carrying capability and other information for single and multispan standing skylines and single span running skylines. In general, the three skyline programs prepare load paths, forces, and cable tension information from inputs of equipment specifications and anchoring geometry. Listings and explanations for all programs are included.
