Cable Logging

From Wikipedia, the free encyclopedia

Cable logging is a logging method primarily used on the West Coast of North America with yarder, loaders and grapple yarders.

The cables can be rigged in several configurations.

There are two classes.

1. High Lead, 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.

Into this there are varieties of loading systems.

While skyline logging requires additional setup time, the vertical lift of the skyline allows faster yarding, which can outweigh the additional labor costs, especially on larger harvest units.

Since the 1980's Grapple Yarders have become popular.
