Book excerpt: Excerpt from Mechanics of Running Skylines The problem of determining tensions in the lines due to load can be solved by analysis of the system with weightless lines. Figure shows a free body diagram of the running skyline carriage with weightless lines. This diagram represents both the single main line systems and those employing a main line plus a line for pulling slack or opening grapples. Since only the main line supports the load, the slack-pulling or opening line is ignored in the analysis. Figure -free body diagram of running skyline carriage. TI and T2 are tension in the upper lines and tension in the lower lines due to load, and W is the weight of the carriage and the logs.
