Abstract
The majority of log volume in the western United States is transported as long logs on stinger-steered pole trailers. Opportunities exist to increase value and reduce costs through hauling longer logs. Hauling longer logs often permits increasing gross vehicle weight, reducing the cost of transport and using less fuel per unit of log volume transported. Longer logs also increase the potential to recover value by retaining more bucking options at the mill. On higher-speed routes, hauling longer logs will decrease fuel consumption if vehicle air resistance is reduced. A number of issues associated with hauling longer logs must be considered, including truck performance on horizontal and vertical curves, gradeability, loading and unloading trucks, mill yard layout, method of log measurement, and bridge limits.
