Skyline logging

Skyline logging (or skyline yarding) is a form of cable logging in which harvested logs are transported on a suspended steel cable (a cableway or "highline") from where the trees are felled to a central processing location.

The skyline's cable loop runs around a drive pulley, generally at the central delivery end, and the return pulley at the collection end; the collection-end pulley may be moved radially to other locations within the constraints of the system and may operate over large areas.

A skyline yarder can pull in 5 to 10 logs at a time, using separate chokers.

The pulleys are mounted on towers or cranes, other trees, ridges, or, in rare cases, helium balloons.
