Cable logging equipment is usually used in steep country because it is the most efficient option and it minimises erosion. The equipment consists of a yarder containing a vertical pole from which a skyline cable extends down into the forest to where the trees are being logged. The trees are felled by a person with a chainsaw and are attached to the cable. They are then pulled up to the yarder which has a dump next to it. There, the logs are processed and then loaded onto trucks.
