Abstract

Describes a delay-free-cycle time equation for the Koller K300 skyline yarder operating on steep slopes in the Northeast. Using the equation, the average delay-free-cycle time was 5.72 minutes. This means that about 420 cubic feet of material per hour can be produced. The important variables used in the equation were slope yarding distance, lateral yarding distance, volume per turn, and stem volume. Cable yarding has an advantage of minimizing the impact on environmentally sensitive areas, especially when complying with Best Management Practices (BMP's) and other forest practices regulations.
