Cable logging or skyline logging is a logging method primarily used on the West Coast of North America with yarder, loaders and grapple yarders, but also in Europe (Austria, Switzerland, Czech Republic, France, Italy). The cables can be rigged in several configurations. There are two classes. 1. * High lead logging, in which a simple loop of cable runs from the yarder out through pulley blocks anchored to stumps at the far end of the cut. 2. * Skyline, in which a carriage, pulled by hauling cables, runs along a skyline cable, providing vertical lift to the logs.
