Application of hook-lift trucks in centralized logging slash grinding operations

Background: Chip vans are large trucks commonly used for transporting comminuted woody biomass from forests, provided the roads are suitable for the truck. Smaller trucks can effectively negotiate adverse road conditions such as sharp curves and steep grades and improve access to forest residues (i.e., logging slash). Discussion: This study evaluated the operational performance and costs of a forest biomass harvesting system, utilizing a hook-lift truck in centralized grinding operations in northern California. Conclusion: A centralized grinding operation utilizing a hook-lift truck was cost effective in collecting previously inaccessible forest residues for energy production. The total system production cost (woods landing-to-chip van) was estimated at US$32.98/bone dry ton (BDT) with an hourly production of 10-37 BDT and a total production of 267.5 BDT.
