Abstract: A method of preparing load spectrum of non-stationary random load with sectional operating characteristics has been studied by analyzing the random load in loader and ferk lift truck. Two new concepts of operating sectional drawing and shoveling by shoveling spectrum have been advanced for loaders. The method in this paper can also be used to prepare the load spectrum in other construction machinery with sectional operating characteristics.
