Motor Truck Logging Methods

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

In this paper an attempt has been made to bring together some useful facts concerning the application of the motor truck to the logging industry. The term motor truck as here used is applied to the ordinary truck type of motor vehicle with trailer adapted to carrying logs, and does not include the tractor and the caterpillar tractor. These latter types present special problems of their own. In the following pages the discussion of motor truck logging is premised upon conditions as they exist in the forests of the Pacific Northwest. Motor trucks in the logging industry are a comparatively recent development. As nearly as can be determined, the first use of a truck in a logging operation was made in this region by Palms and Shields near Covington, Washington, in the spring of 1913. Since that time various types of road construction suitable for heavy trucks have been devised and the use of the motor truck for logging has steadily increased until at the present time there are about six hundred trucks operating in the woods in the Northwest. The first real progress in the use of the motor truck for logging purposes came with the development of the trailer. Although the motor truck has been brought to its present high state of perfection in eastern factories the problem of adapting it to the hauling of massive logs was solved in Seattle, Washington, with the perfecting of a trailer which could carry unprecedented loads and stand up under the speed attained by a motor truck. In the early attempts to design a trailer, it was found that too great tractive effort on the part of the truck was required if the trailer was patterned after older types with simply increased dimensions in all of its parts. Through successive improvements the modern form of heavy duty trailer was finally evolved. It has solved a serious problem by permitting the hauling of heavier weights with the aid of the trailer than is possible with the use of the truck alone. With the help of the trailer and an adjustable reach, the motor truck has successfully entered the logging field. ......Buy Now (To Read More)
