SP-11-31 pre-skidding and skidding of full trees with yarder
Full trees are moved to a landing (roadside landing, landing pad etc.) suspended under a carriage that runs on a cable (skyline). In a limited corridor tress can be pre-skid to the skyline as well before they are extracted. Different types and configurations are available (live, standing, running skyline, self-propelled carriage, swing yarders - carriages with cable or grapple).
