Yarder

[1] It generally consists of an engine, drums, and spar, but has a range of configurations and variations, such as the swing yarder.

Popular brands included Willamette, Skagit, Washington, Tyee, or Lidgerwood and Clyde, built by Clyde Ironworks in Duluth, Minnesota.

The Clyde was capable of retrieving logs from four different points at the same time.

Once the logs were attached and a clearance signal was sent for retrieval, the logs could be skidded at a speed of 1000 feet per minute, which is around 10 mph (1MPH = 88 fpm = 26.8 meter per minute).

[citation needed] Cable logging, used primarily on the North American west coast, uses a yarder, loaders and grapple yarders.
