Development of Improved Cable Yarding Productivity in Southern Africa for Small-Sized Trees

摘要

Production rates of cable yarding by fixed skyline in Southern Africa were found to be low, usually between 50 m3 to 60 m3 of timber per day on average. Investigations identified four major sources of lost productivity. Implementation of simple techniques selected to reduce losses resulted in a quadrupling of productivity though only a tripling is expected in the long term.
