Washington Iron Works

Washington Iron Works was a company in Seattle, Washington, that built these steam skidders. The company was active from 1882 until the 1980s when its various divisions – manufacturing cranes, logging equipment, and presses – were gradually sold off. The Works closed in 1986.

Washington Iron Works engines revolutionized steam logging in the 1920s and 1930s. The steam-powered winches were mounted on heavy log skid frames which allowed the winch to be transported to new sites. Many Washington skidders can still be seen in North America.

Operation

The Washington Winch operated either a high lead or a skyline system. The high lead system was not often used as it only partially lifted the logs off the ground, which caused the logs to become caught in rocks, and left behind a "snig track", which deepened over time. The skyline system involved two large spars (trees) used to create a "flying fox" to lift logs over the rough ground. Riggers climbed 60m up a large tree and headed the trunk, which would cause the tree to sway violently. They then secured the spar with guy cables and attached the tackle. This operation was dangerous and physically demanding, often taking a full day, with lunch sent up on a rope. The Washington Winch was used to harvest Alpine Ash which would then be used for high-value products such as furniture, flooring and architraves.
