FEASIBILITY OF DEVELOPING A TRIDEM AXLE TRACTOR FOR LOG HAULING APPLICATIONS

As the distances between the timber resource and the processing mills have increased, log-hauling vehicle operators in the interior of B.C. have increased the payload capacity of their tractor/trailer combinations by adding more axles to the trailers to minimize transportation costs. This report describes a study on the feasibility of building a tractor truck with a tridem group of axles for log-hauling applications. The study evaluated the stability, traction, and operational productivity of the tridem axle group; investigated a means of improving the braking safety of such vehicles operating on public highways; examined the possibility of developing a log-hauling vehicle that would be less damaging to the pavement on public highways; investigated the possibility of improving the off-highway tractive ability of log-hauling vehicles; and demonstrated and evaluated new technology for log-hauling industry. The first phase of the research, reported here and conducted in 1988-89, included a literature search, a hardware search, a traction and gradeability study, and a vehicle dynamics analysis.
