Resumen
In the Southern U.S., timber is transported from harvest sites to mills by many small trucking companies. Few studies have examined the structure and challenges facing these businesses. This study involved interviews with 18 log truck owners operating in the state of Georgia, USA. Participants operated in all forested regions of Georgia and included wood dealers, contract haulers, logging businesses, logging and trucking businesses, and large, diversified trucking businesses. Fleet sizes ranged from zero trucks (recently ceased hauling) to more than 50 log trucks. Log trucks were driven an average of 127,324 km year−1 and delivered an average of 17,410 t year−1. Participants averaged 48% loaded km. Analysis suggests the current combination of average payload, percent-loaded km, and published haul rates make it difficult for log trucking companies to be profitable. The most important challenges faced by log truck owners were a shortage of qualified drivers and rising truck insurance premiums, which were identified as the greatest challenge by 44% and 39% of participants, respectively. Increasing percent-loaded km, reducing turn times at mills and harvest sites, providing driver training, and adopting technologies, such as global positioning system tracking and onboard cameras, could improve transportation efficiency and safety.
