Maximizing the Standing Skyline Log Load Using a Variable Length Tagline

The standing skyline continues to be a common cable logging configuration. In payload analysis it is usually assumed that the tagline (line connecting logs carriage) length held constant while yarding turn up corridor. We show this assumption severely limits load-carrying capacity for skylines operating with partial suspension. suggest smart carriage technology could markedly increase log load through use of variable tagline, and thus productivity. A methodology estimating presented. illustrate increases 30–40 percent in are possible tagline.
