Abstract:Load data from modified and conventional timber haul trucks were compared to determine if weight-related changes to truck and trailer components affect truck load characteristics. Resulting estimates of load weight were used to measure the economic potential of these modifications. Statistical analysis indicates that gross, net, and tare mean weights for the modified vehicles differed significantly from mean weights for the conventional haul vehicles. Separate comparisons of net weights for pulpwood and chip'n'saw loads suggest that weight-related modifications can significantly improve net load weight, regardless of the type of load being carried. An economic analysis was made to determine the incremental value of investing in a modified haul vehicle for a contract hauler in the South. The incremental internal rate of return for a modified truck-trailer configuration was estimated at 242.7% annually. The incremental net present value for the investment at a 10% hurdle rate was estimated at $16,442 over a 5-year operating life. South. J. Appl. For. 14(3):133-136.
