Abstract
Detailed time-and-motion studies were conducted on a harvesting system that included roll-off bins and bunks used in conjunction with a Timbco harwarder at two study sites in western Montana. Data from these studies were used in multiple regression analysis to develop production equations for total cycle time for each of the seven processes involved in harvesting round- wood products and woody biomass. Independent variables used to create these production equations included distance traveled, piece size, number of pieces, and a site term. Comparisons were made between developed equations from this study and other published equations. Using standardized variables, production rates (tons/hour) of the observed processes were developed. Forest managers can apply these equations to determine the cycle time for a process and, when paired with tons per cycle, the production rate of the roll-off and hook-lift system can be determined and compared to other roundwood and biomass harvesting and treatment options.
