Motor Truck Logging Methods / Engineering Experiment Station Series, Bulletin No. 12

A practical technical guide addressing use of motor trucks and trailers for hauling logs in the Pacific Northwest. It surveys early adoption and development of heavy-duty trailers, compares motor trucks with railroad hauling, and provides detailed chapters on operating costs, equipment design, insurance, trailers and braking, depreciation, road and bridge construction, yarding, loading and unloading methods, inclines and snubbing, turning devices, telephone use, and time studies. It emphasizes careful site-by-site economic analysis, road-building practices, and operational procedures to determine when motor-truck methods are appropriate.
