Transport of dry beetle-killed wood may result in hauling inefficiencies because the lower density of this wood may not allow maximum axle weights to be achieved. The Forest Engineering Research Institute of Canada (FERIC) undertook a project to determine if 7- and 8-axle CTL log hauling configurations are able to reach maximum axle weights when hauling dry beetle-killed wood. FERIC calculated the increase in per-tonne-hour hauling costs to the mill and to the log hauling contractor as a result of hauling underweight loads, and investigated options to increase the load carrying envelope with the use of wider bunks and higher loads. FERIC also conducted a loading trial to determine if a fourth bundle of 5.0 m logs can be added onto B-train configurations.
