Forestry operations in the 1990's challenges and solutions, Proceedings of the 14th annual meeting of the Council of Forest Engineers, July 22-25, 1991: Nanaimo, British Columbia, CA. Productivity and cost estimators for conventional ground-based skidding on steep terrain using preplanned skid roads. Although estimated skidding costs were higher when the designated skid roads were used, the increased costs may be offset by a reduction in adverse stand and site impacts, and a reduction in the safety hazards often associated with ground-based skidding on steep terrain.Įrickson, Michael D. Productivity levels decreased while costs increased as the amount of winch line cable needed to be pulled to choke logs increased. Comparisons of productivity and costs were analyzed for an overland random access skidding method, verses a skidding method utilizing a network of preplanned designated bladed skid roads. Continuous time and motion study techniques were used to develop productivity and cost estimators for the skidding component of ground-based logging systems, operating on steep terrain using preplanned skid roads.
