Swing yarder

However, if the ground is too steep for the operation of such machinery, it is common practice to rig some sort of a cable system for moving the wood.

This machine is most suitable for steep ground where it is difficult to access the logs with other machinery.

While there are various rigging options, the most common one uses a grapple that can be lowered onto a logs and closed via the cable system.

This bearing permits the boom and cable system to be 'swung' across a setting without relocating the machine.

An experienced operator uses timing and cable tension to swing the grapple to the desired location.
